Released/updated on: 2017-06-16

Geographic coverage: Canada, Quebec (province)

Time period: 1999-01-01--2009-12-31, 2007-06-01--2008-06-30

In this study, researchers used capture-recapture sampling and multiple data sources to gauge the impact of drug trafficking in Quebec, Canada on the United States drug market. The main analyses were based on arrest data that were obtained for Quebec. In addition, analysis of the chemical composition and price assessments of the Quebec synthetic drugs was done.

The study includes one SPSS data file (Quebec Arrest Data (Synthetic Drugs Cases, September 2014; n=20261)-ICPSR.sav ; n=20,261 ; 13 variables) and one Excel data file (Chemical composition of seized synthetic drugs.xls ; n=365 ; 14 variables).

Spatial analyses of border seizure data was performed by the researchers, but these data are not available at this time. The data used for these analyses concerned synthetic drug seizures at Canadian borders from 2007 to 2012. The dataset was provided by the Canadian Border Services Agency (CBSA). For each seizure, the specific border crossing where the seizure was made was provided, as well as the value of the seizure (except for precursors), the country of origin and the type of drug seized. The types of drugs were classified into five types: (1) Precursors, (2) MDMA, (3) Amphetamine, (4) Methamphetamine and (5) Others. Most of the seizures (86.6 percent) were classified in this last category. The country of origin of the seizure was also provided.

Time period: 2013-01-01--2013-01-31, 2011-12-01--2011-12-31, 2011-05-01--2011-05-31, 2007-01-01--2012-12-31, 2011-12-01--2011-12-31, 2013-01-01--2013-01-31, 2011-05-01--2011-05-31, 2007-01-01--2012-12-31, 2012-01-01--2012-01-31, 2011-10-01--2012-04-30, 2007-01-01--2012-12-31, 2013-01-01--2013-01-31

The study involved a three-year evaluation of two efforts to target crime stemming from the Southern Border of the United States - one which funded greater participation by local officers on four FBI-led multi-jurisdictional task forces (MJTFs) and another that created a new multi-jurisdictional team. As part of this evaluation, researchers documented the level of inter-agency collaboration and communication when the project began, gathered information regarding the benefits and challenges of MJTF participation, measured the level of communication and collaboration, and tracked a variety of outcomes specific to the funded MJTFs, as well as three comparison MJTFs. Multiple methodologies were used to achieve these goals including surveys of task forces, law enforcement stakeholders, and community residents; law enforcement focus groups; program observations; and analysis of archival data related to staffing costs; task force activities; task force target criminal history; and prosecution outcomes.

The study is comprised of several data files in SPSS format:

Imperial County Law Enforcement Stakeholder Survey Data (35 cases and 199 variables)
Imperial County Resident Survey (402 cases and 70 variables)
Imperial Task Force Survey (6 cases and 84 variables)
Prosecution Outcome Data (1,973 cases and 115 variables)
San Diego County Resident Survey (402 cases and 69 variables)
San Diego Law Enforcement Stakeholder Survey (460 cases and 353 variables)
San Diego Task Force Survey (18 cases and 101 variables)

Evaluation of the Bureau of Justice Assistance's Indian Alcohol and Substance Abuse Demonstration Programs, 2002-2006 (ICPSR 25741)

Released/updated on: 2015-01-20

Geographic coverage: United States, Washington

Time period: 2002-01-01--2006-12-31

The purpose of this study was to determine whether the Lummi Nation's Community Mobilization Against Drugs (CMAD) Initiative successfully achieved its four stated goals, which were to reduce illicit drug trafficking, reduce rates of substance use disorder and addiction, prevent drug abuse and underage drinking among youth, and mobilize the community in all aspects of prevention, intervention, and suppression of alcohol and drug use, drug abuse, and drug trafficking. The study also aimed to evaluate whether the outcomes of the demonstration project had application for other tribal communities confronting similar public safety issues related to substance abuse. Qualitative information from focus group interviews was collected. Six focus groups were held with individuals representing the following populations: service providers, policy makers, adult clients and family members, youth, traditional tribal healers, and community members. In addition to the focus groups, the evaluation team conducted an interview session with two traditional providers who preferred this format. All focus groups were conducted on-site at Lummi by two trained moderators from the evaluation team. There were six different sets of questions, one for each group. Each set included 9 to 10 open-ended questions, which addressed knowledge and impact of the Community Mobilized Against Drugs (CMAD) Initiative; issues or problems with the Initiative; how the community viewed its actions; the importance and inclusion of a cultural perspective (traditional healers and others) in implementing various aspects of the CMAD Initiative; and how the Initiative had affected work and networking capabilities, policy making decisions, and/or treatment. Participants were also asked to think about what they would like CMAD to address and about their perceptions and definitions of some of the service barriers they may be experiencing (clients, community, and/or youth). All of the focus groups were openly audio taped with full knowledge and agreement of the participants.

Geographic coverage: Mindanao, Philippines, Luzon, Manila, Visayas, Global

Time period: 2003-01-01--2003-12-31

Social Weather Stations Surveys are SWS-initiated national surveys of the general Filipino public. Dating from 1986, initially semi-annual, and quarterly since 1992, these surveys are meant to supplement, not duplicate, existing government statistics. They include both core indicators monitored regularly and items on contemporary issues. A standard Social Weather Survey has two questionnaires, one for the household head and one for a random adult. The Third Quarter 2003 Social Weather Survey was fielded August 30 to September 14, 2003, throughout the country. It used face-to-face interviews of 1,200 respondents divided into random samples of 300 each in Metro Manila, Balance Luzon, Visayas, and Mindanao. Adults, aged 18 years and older, were asked their views on issues concerning the general topics of economics, governance, politics, diplomacy, and society, as well as issues of current public interest in the Philippines. The survey also gathers information from household heads about the members of the household and household characteristics. Demographic variables include sex, age, religion, education, marital status, household composition, language use, and occupation.

Released/updated on: 2012-08-22

Geographic coverage: New York City, Oregon, District of Columbia, San Diego, San Antonio, United States, Chicago, Illinois, Texas, Portland (Oregon), California, New York (state)

Time period: 1995-01-01--1996-12-31

This study was designed to address the practical and policy implications of various drug market participation patterns. In 1995, the Office of National Drug Control Policy (ONDCP) and the National Institute of Justice (NIJ) collaborated on a project called the Procurement Study. This study was executed as an addendum to NIJ's Drug Use Forecasting (DUF) program (DRUG USE FORECASTING IN 24 CITIES IN THE UNITED STATES, 1987-1997 [ICPSR 9477]) with the goal of extending previous research in which heroin users were interviewed on various aspects of drug market activity. The present study sought to explore additional features of drug market participation and use, both within and across drug types and cities, and included two additional drugs -- powder cocaine and crack cocaine. Data were collected from recently arrested users of powder cocaine, crack cocaine, and heroin in six DUF cities (Chicago, New York, Portland, San Diego, San Antonio, and Washington, DC). Each of the three files in this collection, Crack Data (Part 1), Heroin Data (Part 2), and Powder Cocaine Data (Part 3), is comprised of data from a procurement interview, urine test variables, and a DUF interview. During the procurement interview, information was collected on purchase and use patterns for specific drugs. Variables from the procurement interview include the respondent's method of using the drug, the term used to refer to the drug, whether the respondent bought the drug in the neighborhood, the number of different dealers the respondent bought the drug from, how the respondent made the connection with the dealer (i.e., street, house, phone, beeper, business/store, or friends), their main drug source, whether the respondent went to someone else if the source was not available, how the respondent coped with not being able to find drugs to buy, whether the respondent got the drug for free, the means by which the respondent obtained money, the quantity and packaging of the drug, and the number of minutes spent searching for, traveling to, and waiting for their last purchase. Urine tests screened for the presence of ten drugs, including marijuana, opiates, cocaine, PCP, methadone, benzodiazepines (Valium), methaqualone, propoxyphene (Darvon), barbiturates, and amphetamines (positive test results for amphetamines were confirmed by gas chromatography). Data from the DUF interview provide detailed information about each arrestee's self-reported use of 15 drugs. For each drug type, arrestees were asked whether they had ever used the drug, the age at which they first used the drug, whether they had used the drug within the past three days, how many days they had used the drug within the past month, whether they had ever needed or felt dependent on the drug, and whether they were dependent on the drug at the time of the interview. Data from the DUF interview instrument also included alcohol/drug treatment history, information about whether arrestees had ever injected drugs, and whether they were influenced by drugs when the crime that they were charged with was committed. The data also include information about whether the arrestee had been to an emergency room for drug-related incidents and whether he or she had had prior arrests in the past 12 months. Demographic data include the age, race, sex, educational attainment, marital status, employment status, and living circumstances of each respondent.

Geographic coverage: United States

Time period: 1992-04-20--1992-04-23

This poll is part of a continuing series of monthly surveys that solicit public opinion on the presidency and on a range of other political and social issues. Respondents were asked to comment on what they thought was the most important problem facing the country, and to give their approval rating of George Bush with respect to his handling of the presidency, foreign policy, and the economy. Questions were posed regarding respondents' vote intentions for the 1992 presidential election, their opinions of potential 1992 presidential candidates, the likelihood of their voting in either a Republican or Democratic presidential primary or caucus, their candidate preferences for the Democratic and Republican presidential nominations, and issues presidential candidates should emphasize. Those surveyed were asked whether most members of Congress deserved reelection, whether particular representatives deserved reelection, and whether Bill Clinton had told the truth when answering charges about his personal life. Questions on the Bush administration evaluated its performance in dealing with illegal drugs, education, the economy, and the development of policies. Respondents were asked whether Bush, Clinton, and Ross Perot were liberal, moderate, or conservative, whether they had strong qualities of leadership, and who had more honesty and integrity. The poll also posed a series of questions about the media including whether the names of people accused of crimes and those who were victims of crimes should be made public, whether the media had gone too far in disclosing details of presidential candidates' private lives, and whether the media had been harder on Bush and Clinton than on the other presidential candidates. Respondents were also asked whether the government was in such bad shape that it needed a strong leader who would take charge, whether the federal government should run like a business with one person in charge, and whether it was better for people to take the law into their own hands rather than wait for the government to act. Those surveyed were asked if there was a connection between what a politician says and what he or she does after being elected, whether who was elected made any difference, whether the government would work better if all new people were elected, and whether a politician's methods mattered as long as he or she managed to get the right thing done. Additional questions dealt with the state of the economy, drug testing in the workplace, the respondent's financial situation, organized labor, the national economy, big business, the First Lady's working outside the White House, television news coverage of the presidential campaign, the most important quality the next president should have, call-in polls and programs on radio and television, and the amount of attention the government and Congress pay to what people think. Background information on respondents includes involvement in a labor union, sex, race, age, education, religious preference, family income, political orientation, and party preference.

United Nations Surveys of Crime Trends and Operations of Criminal Justice Systems Series, Waves 1-10, 1970-2006 (ICPSR 26462)

Released/updated on: 2010-07-22

Geographic coverage: South America, Asia, Europe, Africa, North America, Global, Latin America

Time period: 1970-01-01--2006-12-31

The major goal of the United Nations Surveys on Crime Trends and the Operations of Criminal Justice Systems was to collect data on the incidence of reported crime and the operations of criminal justice systems with a view to improving the analysis and dissemination of that information globally. Surveys were distributed to officials in every member country of the United Nations. Designated officials completed the surveys to the best of their abilities given the country's available data. The survey questionnaire consisted of a series of questions which asked for data, primarily statistical, on the main components of the country's criminal justice system, for the given time period of the wave of data collection. To date, there have been ten waves of data collection. Crime variables include counts of recorded crime for homicide, assault, rape, robbery, theft, burglary, fraud, embezzlement, drug trafficking, drug possession, bribery, and corruption. There are also counts of suspects, persons prosecuted, persons convicted, and prison admissions by crime, gender, and adult or juvenile status. Other variables include the population of the country and largest city, budgets and salaries for police, courts, and prisons, and types of sanctions, including imprisonment, corporal punishment, deprivation of liberty, control of freedom, warning, fine, and community sentence. The countries participating in the survey and the variables available vary across the ten waves. There are two versions of the Wave 2 data (Part 2: Wave 2a , 1975-1980; Part 3: Wave 2b, 1975-1980) because, for various reasons, the variables from Wave 1 and some variables from Wave 2 were combined into one dataset. Similarly, some variables from Wave 2 were combined into one dataset with the variables from Wave 3. For this study, the combined Wave 1 and Wave 2 dataset was separated into Parts 1 and 2 (Wave 1, 1970-1975, and Wave 2a, 1976-1980, respectively) and the combined Wave 2 and Wave 3 dataset was separated into Parts 3 and 4 (Wave 2b, 1975-1980, and Wave 3, 1980-1986, respectively).

Reducing Violent Crime and Firearms Violence in Indianapolis, Indiana, 2003-2005 (ICPSR 20357)

Released/updated on: 2009-01-30

Geographic coverage: Indiana, United States, Indianapolis

Time period: 2003-06-01--2005-03-31

The lever-pulling model was first developed as part of a broad-based, problem-solving effort implemented in Boston in the mid-1990s. The lever-pulling strategy was a foundational element of many collaborative partnerships across the country and it was a central element of the strategic plans of many Project Safe Neighborhoods (PSN) jurisdictions. This effort attempted to deter the future violent behavior of chronic offenders by first communicating directly to them about the impact that violence had on the community and the implementation of new efforts to respond to it, and then giving credibility to this communication effort by using all available legal sanctions (i.e., levers) against these offenders when violence occurred. The purpose of the study was to perform an experimental evaluation of a lever-pulling strategy implemented in Indianapolis, Indiana. Probationers were randomly assigned to the law enforcement focused lever-pulling group, the community leader lever-pulling group, or a regular probation control group during six months between June 2003 and March 2004. There were a total of 540 probationers in the study--180 probationers in each group. Probationers in the law enforcement focused lever-pulling group had face-to-face meetings with federal and local law enforcement officials and primarily received a deterrence-based message, but community officials also discussed various types of job and treatment opportunities. In contrast, probationers in the community leader lever-pulling group attended meetings with community leaders and service providers who exclusively focused on the impact of violence on the community and available services. Three types of data were collected to assess perceptions about the meeting: offending behavior, program participation behavior, and the levers pulled. First, data were collected using a self-report survey instrument (Part 1). Second, the complete criminal history for probationers (Part 2) was collected one-year after their meeting date. Third, all available probation data (Part 3) were collected 365 days after the meeting date. Part 1, Self-Report Survey Data, includes a total of 316 variables related to the following three types of data: Section I: meeting evaluation and perception of risk, Section II: Self-reported offense and gun use behavior, and Section III: Demographics. Part 2, Criminal History Data, includes a total of 94 variables collected about the probationer's complete offending history as well as their criminal activities after the treatment for one year. Part 3, Probation Data, includes a total of 249 variables related to probation history and other outcome data.

This data collection is part of a continuing series of monthly surveys that evaluate the Bush presidency and solicit opinions on a variety of political and social issues. Topics covered include the state of the economy, foreign affairs, the federal budget deficit, and relations with the Soviet Union. Respondents were asked if they trusted the Democrats or the Republicans to do a better job in coping with the main problems facing this country, if they thought that Bush should drop his "no new taxes" policy and consider raising taxes in order to reduce the federal budget deficit, and if they felt federal civil rights laws needed to be strengthened. Respondents also were asked a detailed series of questions regarding the Soviet Union and the Eastern Bloc countries. They were asked about American and Soviet influences in world affairs, impressions of Mikhail Gorbachev and George Bush, whether they thought changes that had occurred recently in the Soviet Union and Eastern Bloc countries would result in a peaceful world, and whether these changes would provide the United States with major economic opportunities. In addition, respondents were asked to identify the greatest threat to the United States from among the following: the military power of the Soviet Union, Middle Eastern terrorism, the economic strength of Japan, and South American drug traffickers. Respondents were also queried about how important it was to the United States that Gorbachev remain in power and whether they thought the United States should officially recognize Lithuania, Latvia, and Estonia as independent counties. Other topics covered include cuts in military spending, cuts in nuclear arms, sending food, clothing, and consumer goods to the Soviet Union, Soviet emigration to the United States, the upcoming summit meeting between Bush and Gorbachev, voting preference if the House of Representatives election were held that day, and whether a candidate's stand on taxes would influence the respondent's vote. Background information on respondents includes political alignment, 1988 presidential vote choice, education, age, religion, social class, marital status, number of people in household, labor union membership, employment status, race, income, sex and state/region of residence.

Those polled identified the most important problem facing Prince William County, whether they would like to live in Prince William County in five years, and whether they would move if housing was not less expensive there relative to other areas around Washington. Respondents were asked to assess the treatment of residents of the east and west sides of the county by government officials, how well their local government was providing public services, as well as the availability of cultural activities, entertainment, and retail stores and restaurants in Prince William County. Residents were also asked for their opinion on problems facing their local public schools, such as overcrowding, gang violence, and poor school facilities, and whether they would be willing to sacrifice city services or pay more taxes to provide more money to public schools. Other topics covered the growth rate in Prince William County, and whether limits should be placed on residential and commercial development. Additional questions asked respondents how long they had lived in the Prince William County area, the location of their previous residence, and whether they had any children living in and attending school in Prince William County. Demographic variables include sex, age, race, education level, marital status, political party affiliation, and household income.

The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. The Self Report of Offending was a self-report questionnaire focused on a participant's involvement in antisocial behavior and the legal consequences of that behavior. It was administered to Cohorts 6, 9, 12, 15, and 18.

Impact of Gang Migration: Effective Responses by Law Enforcement Agencies in the United States, 1992 (ICPSR 2570)

Released/updated on: 2006-03-30

Geographic coverage: United States

Time period: 1992-01-01--1992-12-31

This study was the first attempt to investigate gang migration systematically and on a national level. The primary objectives of the study were (1) to identify the scope of gang migration nationally, (2) to describe the nature of gang migration, (3) to assess the impact of gang migration on destination cities, and (4) to describe the current law enforcement responses to the migration of gangs and identify those that appeared to be most effective for various types of migration. Two phases of data collection were used. The major objective of the initial phase was to identify cities that had experienced gang migration (Part 1). This was accomplished by distributing a brief mail questionnaire in 1992 to law enforcement agencies in cities identified as potential gang or gang migration sites. The second major phase of data collection involved in-depth telephone interviews with law enforcement officers in cities that had experienced gang migration in order to develop descriptions of the nature of migration and police responses to it (Part 2). For Part 1, information was collected on the year migration started, number of migrants in the past year, factors that deter gang migration, number of gang members, names of gangs, ethnic distribution of gang members and their drug market involvement, number of gang homicides, number of 1991 gang "drive-bys", and if gangs or narcotics were specified in the respondent's assignment. For Part 2, information was collected on the demographics of gang members, the ethnic percentage of drug gang members and their involvement in distributing specific drugs, and the influence of gang migrants on local gang and crime situations in terms of types and methods of crime, drug distribution activities, technology/equipment used, and targets of crime. Information on patterns of gang migration, including motivations to migrate, drug gang migration, and volume of migration, was also collected. Local responses to gang migration covered information sources, department policies relative to migration, gang specialization in department, approaches taken by the department, and information exchanges and coordination among local, state, and federal agencies.

Criminal Behavior of Gangs in Aurora and Denver, Colorado, and Broward County, Florida: 1993-1994 (ICPSR 2626)

Released/updated on: 2006-03-30

Geographic coverage: Aurora, United States, Colorado, Denver, Florida

Time period: 1993-01-01--1994-12-31

This study was undertaken to measure the criminal behavior of gangs, including their involvement in delinquent behavior such as drug use and drug trafficking activities, and to compare gang behavior with that of youth who were at risk, but who had not yet become active in gangs. The project assessed the role that gangs play in the lives of youth whose living conditions are otherwise comparable. In order to study the criminal behavior of gangs, investigators sought to interview 50 gang members and 50 non-gang, at-risk youth at two sites in Colorado and one site in Florida. A large portion of the interview questions asked in both the gang member interview and the at-risk youth interview were parallel. The following variables appear in both the gang member and at-risk youth files (Parts 1 and 2 respectively) created for this data collection: gang popularity variables (respondents' perceptions of the positive and negative attributes of a gang, and why gangs endure over time), drug involvement variables (whether respondents or fellow members/friends sold various types of drugs, why selling drugs increases a person's "juice", the drug source organization, and where they traveled to get the drugs), criminal history variables (the reasons why respondents believed they were able to get away with crimes, their first arrest age, and their most serious arrest charge), personal activity variables (whether respondents or fellow members/friends participated in dances, sporting events, fighting, drug use or selling, shoplifting, assaulting people, or burglarizing homes), variables concerning the future (whether respondents would join a gang again/join a gang today, why some gangs survive and others don't, and how respondents see their future), and demographic variables (respondents' age, sex, race, city, neighborhood, school, school status, type of work, marital status, and relationship with parent(s)). In addition, Part 1, the Gang Member Data, contains gang status variables (gang symbols, gang nickname, gang turf, and how members define a gang) and gang membership variables (roles of the respondents within the gang, why members join a gang, what the most important gang rule is, and what happens to those who refuse the gang). Part 2, At-Risk Youth Data, contains additional variables on gang contact (the names of gangs who had approached the respondents, methods used to try to get the youths to join, how the youths refused the gang, and what happened as a result of refusing) and prevention (how at-risk youth would advise a young person to react if approached by a gang, and what the youths felt was the best way to prepare children to deal with gangs).

Gang Involvement in "Rock" Cocaine Trafficking in Los Angeles, 1984-1985 (ICPSR 9398)

Released/updated on: 2006-03-30

Geographic coverage: United States, Los Angeles, California

Time period: 1984-01-01--1985-12-31

The purpose of this data collection was to investigate the possible increase in gang involvement within cocaine and "rock" cocaine trafficking. Investigators also examined the relationships among gangs, cocaine trafficking, and increasing levels of violence. They attempted to determine the effects of increased gang involvement in cocaine distribution in terms of the location of an incident, the demographic profiles of suspects, and the level of firearm use. They also looked at issues such as whether the connection between gangs and cocaine trafficking yielded more drug-related violence, how the connection between gangs and cocaine trafficking affected police investigative processes such as intra-organizational communication and the use of special enforcement technologies, what kinds of working relationships were established between narcotics units and gang control units, and what the characteristics were of the rock trafficking and rock house technologies of the dealers. Part 1 (Sales Arrest Incident Data File) contains data for the cocaine sales arrest incidents. Part 2 (Single Incident Participant Data File) contains data for participants of the cocaine sales arrest incidents. Part 3 (Single Incident Participant Prior Arrest Data File) contains data for the prior arrests of the participants in the cocaine arrest incidents. Part 4 (Multiple Event Incident Data File) contains data for multiple event incidents. Part 5 (Multiple Event Arrest Incident Data File) contains data for arrest events in the multiple event incidents. Part 6 (Multiple Event Incident Participant Data File) contains data for the participants of the arrest events. Part 7 (Multiple Event Incident Prior Arrest Data File) contains data for the prior arrest history of the multiple event participants. Part 8 (Homicide Incident Data File) contains data for homicide incidents. Part 9 (Homicide Incident Suspect/Victim Data File) contains data for the suspects and victims of the homicide incidents. Major variables characterizing the various units of observation include evidence of gang involvement, presence of drugs, presence of a rock house, presence of firearms or other weapons, presence of violence, amount of cash taken as evidence, prior arrests, and law enforcement techniques.

In undertaking this data collection, the principal investigators sought to determine (1) whether police enforcement against drug crimes, specifically heroin crimes, had any influence on the rates of nondrug crimes, and (2) what effect intensive law enforcement programs against drug dealers had on residents where those programs were operating. To achieve these objectives, data on crime rates for seven successive years were collected from police records of 30 cities in Massachusetts. Data were collected for the following offenses: murder, rape, robbery, assault, larceny, and automobile theft. The investigators also interviewed a sample of residents from 3 of those 30 cities. Residents were queried about their opinions of the most serious problem facing people today, their degree of concern about being victims of crime, and their opinions of the effectiveness of law enforcement agencies in handling drug problems.

Time period: 1970-01-01--1994-12-31

The United Nations International Crime Prevention and Criminal Justice Branch began the Surveys of Crime Trends and Operations of Criminal Justice Systems (formerly known as the World Crime Surveys) in 1978. The goal of the data collection effort was to conduct a more focused inquiry into the incidence of crime worldwide. To date, there have been five quinquennial surveys, covering the years 1970-1975, 1975-1980, 1980-1986, 1986-1990, and 1990-1994, respectively. Starting with the 1980 data, the waves overlap by one year to allow for reliability and validity checks of the data. For this data collection, the original United Nations data were restructured into a standard contemporary file structure, with each file consisting of all data for one year. Naming conventions were standardized, and each country and each variable was given a unique identifying number. Crime variables include counts of recorded crime for homicide, assault, rape, robbery, theft, burglary, fraud, embezzlement, drug trafficking, drug possession, bribery, and corruption. There are also counts of suspects, persons prosecuted, persons convicted, and prison admissions by crime, gender, and adult or juvenile status. Other variables include the population of the country and largest city, budgets and salaries for police, courts, and prisons, and types of sanctions, including imprisonment, corporal punishment, deprivation of liberty, control of freedom, warning, fine, and community sentence. The countries participating in the survey and the variables available vary by year.

Geographic coverage: Mexico, Global

Time period: 2004-01-01--2004-12-31

The 2004 Mexico Global Views Survey is the first ever comprehensive study of Mexican public and leadership opinion on international affairs. The study is designed to measure general attitudes and values concerning Mexico's relationship with the world rather than opinions on specific foreign policies or issues. This year's survey was conducted in cooperation with the Chicago Council on Foreign Relations' (CCFR) study GLOBAL VIEWS 2004: AMERICAN PUBLIC OPINION AND FOREIGN POLICY (ICPSR 4137). Approximately one-third of the questions on the Mexican and American surveys were asked of the general public in both countries. The thematic emphases of the surveys are the rules and norms of foreign policy interaction between nations and within international organizations and the bilateral relationship between Mexico and the United States. The Mexico survey also emphasizes Mexico's foreign policy decision-making processes as well as its relations with other countries and regions. Part 1 contains data pertaining to a survey conducted to interview members of Consejo Mexicano de Asuntos Internacionales, A.C. (The Mexican Council on Foreign Relations - COMEXI). Part 2 is a survey of the general public. In particular, this study covers (1) Mexicans, Mexican identity, and the world, (2) Mexico's role in the world, (3) global governance, the use of force, and international institutions, (4) foreign relations, and (5) relations with the United States. Regarding Mexicans, Mexican identity, and the world, respondents were asked the importance they placed on various government activities, their interest in the news, their contact with the world, their sense of self-identity, and whether Mexico should have its own foreign policy or follow the United States' lead. On the topic of Mexico's role in the world, respondents were asked their views on the direction of the world, critical threats to Mexico's vital interests, and Mexico's role against terrorism and in world affairs. Concerning global governance, the use of force, and international institutions, respondents rated several international organizations, and commented on the impact of globalization, and foreign investment. On the subject of foreign relations, respondents provided their views on why it was important for Mexico to diversify its relations with the countries of Europe, Latin America, and Asia, the importance of other regions in the world, how to handle disputes in Latin American countries, and their feelings on several individual countries. Regarding relations with the United States, respondents were asked how they felt toward the United States, how much cooperation they favored between the United States and Mexico, who was more responsible for handling common United States-Mexico problems, and their feeling on the North American Free Trade Agreement. A set of influential policy leaders was asked their attitudes in order to assess whether the attitudes of the leaders aligned with those of the general public. Background information on respondents includes gender, age, education, employment status, income, religion, and political party affiliation.

Estimating the Elasticities of Demand for Cocaine and Heroin with Data from 21 Cities from the Drug Use Forecasting (DUF) Program, 1987-1991 (ICPSR 6567)

Released/updated on: 2006-03-30

Geographic coverage: United States

Time period: 1987-01-01--1991-12-31

The objective of this research was to estimate the elasticity of the demand for cocaine and heroin with respect to the price. Price elasticity is the percentage of change in the dependent quantity corresponding to a one-percent change in price. The project involved the development of an econometric model to determine price elasticity, given that national- and city-level data on the consumption of cocaine and heroin are insufficient or nonexistent. The researchers circumvented this lack of data by partitioning the desired elasticity into the product of two elasticities, involving a measurable intermediate quantity whose relationship to the quantity of consumption could be modeled and estimated by measurable techniques. The intermediate quantity used for this project was the fraction of arrestees testing positive for cocaine or heroin as measured by the Drug Use Forecasting (DUF) System. From the Drug Enforcement Administration's (DEA's) System to Retrieve Information from Drug Evidence (STRIDE) data, expected purity was computed by regressing on log quantity and dummy variables for location and quarter. Price series were produced by finding the median standardized price per expected pure gram for each location and quarter. Variables for Part 1, National Data, include year, quarter, standardized prices for a gram of cocaine and a gram of heroin, and expected purity of cocaine and heroin. The Cities Data, Part 2, cover city, year, quarter, number of observations used to compute the median price of cocaine and heroin, standardized prices, and expected purity.

Geographic coverage: United States

Time period: 1992-01-01--1992-12-31

This program evaluation study is intended to capture fully the universe of drug enforcement tactics available in the United States and to assess trends in drug enforcement. The primary objective of the study was to learn more about the application of anti-drug tactics by police: What tactics are used by police to address drug use problems? How widely are these tactics used? What new and innovative tactics are being developed and applied by police? What anti-drug tactics are most effective or show some promise of effectiveness? To answer these questions, state and local law enforcement agencies serving populations of 50,000 or more were mailed surveys. The survey was administered to both patrol and investigation units in the law enforcement agencies. This dual pattern of administration was intended to capture the extent to which the techniques of one unit had been applied by another. The questionnaire consisted primarily of dichotomous survey questions on anti-drug tactics that could be answered "yes" or "no". In each of the 14 categories of tactics, respondents were encouraged to add other previously unidentified or unspecified tactics in use in their agencies. These open-ended questions were designed to insure that a final list of anti-drug tactics would be truly comprehensive and capture the universe of drug tactics in use. In addition to questions regarding structural dimensions of anti-drug tactics, the survey also collected standardized information about the law enforcement agency, including agency size, demographic characteristics and size of the agency's service population, and a description of the relative size and nature of the jurisdiction's drug problems.

Evaluation of the Maricopa County [Arizona] Demand Reduction Program, 1989-1991 (ICPSR 9977)

Released/updated on: 2006-01-12

Geographic coverage: United States, Arizona

Time period: 1989-03-01--1991-05-31

These data were collected to evaluate the Demand Reduction Program, a program initiated in Maricopa County, Arizona, in 1989 to combat drug abuse. A consortium of municipal, county, state, and federal law enforcement agencies developed the program, which stressed user accountability. The Demand Reduction Program had two objectives: (1) to create community-wide awareness of the severity of the drug problem and to alert drug users to the increased risk of legal sanctions, and (2) to adopt a zero-tolerance position of user accountability through an emphasis on increased and coordinated law enforcement activities directed against individual offenders and special treatment programs in lieu of prosecution. Part 1 of the collection, Demand Reduction Program Data, provides information on prosecutor's disposition, arrest date, submitted charges, filed charges, prior charges, disposition of charges, drugs offender used in last three months, information on prior drug treatment, type of attorney, and arrestee's age at arrest, sex, marital status, income, and living arrangement. Part 2 is a Citizen Survey conducted in January 1990, ten months after the implementation of the Demand Reduction Program. Adult residents of Maricopa County were asked in telephone interviews about their attitudes toward drug use, tax support for drug treatment, education, and punishment, their knowledge of the Demand Reduction Program, and demographic information. Parts 3 and 4 supply data from surveys of Maricopa County police officers, conducted in March 1990 and April 1991, to measure attitudes regarding the Demand Reduction Program with respect to (1) police effort, (2) inter-agency cooperation, (3) the harm involved in drug use, and (4) support for diversion to treatment. The two police surveys contained identically-worded questions, with only a small number of different questions asked the second year. Variables include officer's rank, years at rank, years in department, shift worked, age, sex, ethnicity, education, marital status, if officer was the primary or secondary wage earner, officer's perception of and training for the Demand Reduction Program, and personal attitudes toward drug use. Part 5 provides arrest data from the Maricopa County Task Force, which arrested drug users through two methods: (1) sweeps of public and semi-public places, and (2) "reversals," where drug sellers were arrested and replaced by police officers posing as drug sellers, who then arrested the drug buyers. Task Force data include arrest date, operation number, operation beginning and ending date, operation type, region where operation was conducted, charge resulting from arrest, Demand Reduction Program identification number, and arrestee's sex, race, and date of birth.

Evaluation of the Weed and Seed Initiative in the United States, 1994 (ICPSR 6789)

Released/updated on: 2005-11-04

Geographic coverage: United States

Time period: 1994-01-01--1994-12-31

The Department of Justice launched Operation Weed and Seed in 1991 as a means of mobilizing a large and varied array of resources in a comprehensive, coordinated effort to control crime and drug problems and improve the quality of life in targeted high-crime neighborhoods. In the long term, Weed and Seed programs are intended to reduce levels of crime, violence, drug trafficking, and fear of crime, and to create new jobs, improve housing, enhance the quality of neighborhood life, and reduce alcohol and drug use. This baseline data collection effort is the initial step toward assessing the achievement of the long-term objectives. The evaluation was conducted using a quasi-experimental design, matching households in comparison neighborhoods with the Weed and Seed target neighborhoods. Comparison neighborhoods were chosen to match Weed and Seed target neighborhoods on the basis of crime rates, population demographics, housing characteristics, and size and density. Neighborhoods in eight sites were selected: Akron, OH, Bradenton (North Manatee), FL, Hartford, CT, Las Vegas, NV, Pittsburgh, PA, Salt Lake City, UT, Seattle, WA, and Shreveport, LA. The "neighborhood" in Hartford, CT, was actually a public housing development, which is part of the reason for the smaller number of interviews at this site. Baseline data collection tasks included the completion of in-person surveys with residents in the target and matched comparison neighborhoods, and the provision of guidance to the sites in the collection of important process data on a routine uniform basis. The survey questions can be broadly divided into these areas: (1) respondent demographics, (2) household size and income, (3) perceptions of the neighborhood, and (4) perceptions of city services. Questions addressed in the course of gathering the baseline data include: Are the target and comparison areas sufficiently well-matched that analytic contrasts between the areas over time are valid? Is there evidence that the survey measures are accurate and valid measures of the dependent variables of interest -- fear of crime, victimization, etc.? Are the sample sizes and response rates sufficient to provide ample statistical power for later analyses? Variables cover respondents' perceptions of the neighborhood, safety and observed security measures, police effectiveness, and city services, as well as their ratings of neighborhood crime, disorder, and other problems. Other items included respondents' experiences with victimization, calls/contacts with police and satisfaction with police response, and involvement in community meetings and events. Demographic information on respondents includes year of birth, gender, ethnicity, household income, and employment status.

Firearms, Violence, and Youth in California, Illinois, Louisiana, and New Jersey, 1991 (ICPSR 6484)

Released/updated on: 2005-11-04

Geographic coverage: United States, Illinois, Louisiana, California, New Jersey

Time period: 1991-01-01--1991-04-30

Violence committed by and against juveniles was the focus of this study. Two groups were examined: incarcerated (criminally active) juveniles and students in inner-city high schools, since these youths are popularly considered to engage in and experience violence (especially gun-related violence), to belong to urban street gangs, and to participate in the drug trafficking thought to lead to excessive gun violence. Self-administered questionnaires were completed by 835 male inmates in six correctional facilities and 1,663 male and female students from ten inner-city high schools in California, Illinois, Louisiana, and New Jersey. Data collection took place during January through April of 1991. To maximize response rates, inducements of five dollars were offered to the inmates, Spanish-language versions of the questionnaire were provided to inmates who preferred them, and personal interviews were conducted with inmates whose reading skills were less than sufficient to complete the questionnaire on their own. In four schools, principals permitted the inducements to be offered to students to participate in the study. As with the inmate survey, a Spanish-language version of the questionnaire was provided to students who preferred it. The questionnaires covered roughly the same core topics for both inmates and students. Items included questions on sociodemographic characteristics, school experiences, gun ownership, gun use for several types of firearms, gun acquisition patterns, gun-carrying habits, use of other weapons, gang membership and gang activities, self-reported criminal histories, victimization patterns, drug use, alcohol use, and attitudes concerning guns, crime, and violence. In both questionnaires, the majority of the items covered firearms knowledge, acquisition, and use. The remaining items in the inmate survey primarily covered criminal behavior and, secondarily, victimization histories. In the student survey, these priorities were reversed.

Modern Policing and the Control of Illegal Drugs: Testing New Strategies in Oakland, California, and Birmingham, Alabama, 1987-1989 (ICPSR 9962)

Released/updated on: 2005-11-04

Geographic coverage: California, Alabama, Oakland, Birmingham

Time period: 1987-01-01--1989-12-31

These data were collected in Oakland, California, and Birmingham, Alabama, to examine the effectiveness of alternative drug enforcement strategies. A further objective was to compare the relative effectiveness of strategies drawn from professional- versus community-oriented models of policing. The professional model emphasizes police responsibility for crime control, whereas the community model stresses the importance of a police-citizen partnership in crime control. At each site, experimental treatments were applied to selected police beats. The Oakland Police Department implemented a high-visibility enforcement effort consisting of undercover buy-bust operations, aggressive patrols, and motor vehicle stops, while the Birmingham Police Department engaged in somewhat less visible buy-busts and sting operations. Both departments attempted a community-oriented approach involving door-to-door contacts with residents. In Oakland, four beats were studied: one beat used a special drug enforcement unit, another used a door-to-door community policing strategy, a third used a combination of these approaches, and the fourth beat served as a control group. In Birmingham, three beats were chosen: Drug enforcement was conducted by the narcotics unit in one beat, door-to-door policing, as in Oakland, was used in another beat, and a police substation was established in the third beat. To evaluate the effectiveness of these alternative strategies, data were collected from three sources. First, a panel survey was administered in two waves on a pre-test/post-test basis. The panel survey data addressed the ways in which citizens' perceptions of drug activity, crime problems, neighborhood safety, and police service were affected by the various policing strategies. Second, structured observations of police and citizen encounters were made in Oakland during the periods the treatments were in effect. Observers trained by the researchers recorded information regarding the roles and behaviors of police and citizens as well as police compliance with the experiment's procedures. And third, to assess the impact of the alternative strategies on crime rates, reported crime data were collected for time periods before and during the experimental treatment periods, both in the targeted beats and city-wide.

Measuring Crime Rates of Prisoners in Colorado, 1988-1989 (ICPSR 9989)

Released/updated on: 2005-11-04

Geographic coverage: United States, Colorado

Time period: 1988-07-01--1989-12-31

In the late 1970s, the Rand Corporation pioneered a method of collecting crime rate statistics. They obtained reports of offending behavior--types and frequencies of crimes committed--directly from offenders serving prison sentences. The current study extends this research by exploring the extent to which variation in the methodological approach affects prisoners' self-reports of criminal activity. If the crime rates reported in this survey remained constant across methods, perhaps one of the new techniques developed would be easier and/or less expensive to administer. Also, the self-reported offending rate data for female offenders in this collection represents the first time such data has been collected for females. Male and female prisoners recently admitted to the Diagnostic Unit of the Colorado Department of Corrections were selected for participation in the study. Prisoners were given one of two different survey instruments, referred to as the long form and short form. Both questionnaires dealt with the number of times respondents committed each of eight types of crimes during a 12-month measurement period. The crimes of interest were burglary, robbery, assault, theft, auto theft, forgery/credit card and check-writing crimes, fraud, and drug dealing. The long form of the instrument focused on juvenile and adult criminal activity and covered the offender's childhood and family. It also contained questions about the offender's rap sheet as one of the bases for validating the self-reported data. The crime count sections of the long form contained questions about motivation, initiative, whether the offender usually acted alone or with others, and if the crimes recorded included crimes against people he or she knew. Long-form data are given in Part 1. The short form of the survey had fewer or no questions compared with the long form on areas such as the respondent's rap sheet, the number of crimes committed as a juvenile, the number of times the respondent was on probation or parole, the respondent's childhood experiences, and the respondent's perception of his criminal career. These data are contained in Part 2. In addition, the surveys were administered under different conditions of confidentiality. Prisoners given what were called "confidential" interviews had their names identified with the survey. Those interviewed under conditions of anonymity did not have their names associated with the survey. The short forms were all administered anonymously, while the long forms were either anonymous or confidential. In addition to the surveys, data were collected from official records, which are presented in Part 3. The official record data collection form was designed to collect detailed criminal history information, particularly during the measurement period identified in the questionnaires, plus a number of demographic and drug-use items. This information, when compared with the self-reported offense data from the measurement period in both the short and long forms, allows a validity analysis to be performed.

Drug Offending in Cleveland, Ohio Neighborhoods, 1990-1997 and 1999-2001 (ICPSR 3929)

Released/updated on: 2004-06-17

Geographic coverage: United States, Ohio, Cleveland

This study investigated changes in the geographic concentration of drug crimes in Cleveland from 1990 to 2001. The study looked at both the locations of drug incidents and where drug offenders lived in order to explore factors that bring residents from one neighborhood into other neighborhoods to engage in drug-related activities. This study was based on data collected for the 224 census tracts in Cleveland, Ohio, in the 1990 decennial Census for the years 1990 to 1997 and 1999 to 2001. Data on drug crimes for 1990 to 1997 and 1999 to 2001 were obtained from Cleveland Police Department (CPD) arrest records and used to produce counts of the number of drug offenses that occurred in each tract in each year and the number of arrestees for drug offenses who lived in each tract. Other variables include counts and rates of other crimes committed in each census tract in each year, the social characteristics and housing conditions of each census tract, and net migration for each census tract.

Assessment of a Multiagency Approach to Drug-Involved Gang Members in San Diego County, California, 1988-1992 (ICPSR 2022)

Released/updated on: 2002-03-05

Geographic coverage: United States, California

Time period: 1988-01-01--1992-12-31

In 1988, with funds from the Bureau of Justice Assistance (BJA) via the Anti-Drug Abuse Act of 1987, a multiagency task force, Jurisdictions Unified for Drug Gang Enforcement (JUDGE), was created. Spearheaded by the San Diego County District Attorney's Office and representing a unique blend of police officers, probation officers, and deputy district attorneys working together, the JUDGE program targeted documented gang members also involved in drug use and sales. The task force incorporated an intensive supervision approach that enforced conditions of probation and drug laws and provided vertical prosecution for probation violations and new offenses involving targeted offenders. This research project sought to address the following research objectives: (1) to determine if the JUDGE program objectives were met during the grant period, (2) to assess the results of program activities, such as surveillance, special enforcement, and vertical prosecution, in terms of probation violations, arrests, pretrial custody, probation revocations, convictions, and sentences, (3) to evaluate the impact of the program on offenders as measured by recidivism and the need for probation intervention, (4) to assess the cost of JUDGE probation compared to regular probation caseloads, and (5) to provide recommendations regarding the implementation of similar programs in other jurisdictions. This research project consisted of a process evaluation and an impact assessment that focused on the first two years of the JUDGE program, when youthful offenders were the targets (1988 and 1989). The research effort focused only on new targets for whom adequate records were maintained, yielding a study size of 279. The tracking period for targets ended in 1992. For the impact assessment, the research was structured as a within-subjects design, with the comparison focusing on target youths two years before the implementation of JUDGE and the same group two years after being targeted by JUDGE. Data were compiled on the juveniles' age at target, race, sex, gang affiliation, type of target (gang member, drug history, and/or ward), status when targeted, and referrals to other agencies. Variables providing data on criminal histories include age at first contact/arrest, instant offense and disposition, highest charges for each subsequent arrest that resulted in probation supervision, drug charges, highest conviction charges, probation conditions before selection date and after JUDGE target, number of contacts by probation and JUDGE staff, number of violations for each probation condition and action taken, and new offenses during probation. For the process evaluation, case outcome data were compared to project objectives to measure compliance in terms of program implementation and results. Variables include number of violations for each probation condition and action taken, and number of failed drug tests. The consequences of increased probation supervision, including revocation, sentences, custody time, and use of vertical prosecution, were addressed by comparing the processing of cases prior to the implementation of JUDGE to case processing after JUDGE targeting.

Foreign Policy Leadership Project, 1976-1996 (ICPSR 2614)

Released/updated on: 1999-02-03

Geographic coverage: United States, Global

Time period: 1976-01-01--1996-12-31

The Foreign Policy Leadership Project (FPLP) has conducted extensive quadrennial mail surveys of elite civilian and military opinion since 1976. The cohort varies from year to year, and is drawn from organizations such as Who's Who, labor leadership, the Department of Defense, foreign service officers, the National War College, the press corps, politicians, and clergy leaders. Survey topics focus on United States foreign policy and foreign affairs. Specific issues vary from year to year, although a series of topics are repeated throughout the years. These topics include the importance of foreign policy goals such as containing communism, improving the global standard of living, defending United States allies, protecting United States interests abroad, strengthening the United Nations, combating world hunger, protecting the environment, controlling world population, and ending the illegal drug trade. Respondents are also asked to rate United States effectiveness in those areas. Additional recurring topics include the causes of war, approaches to world peace, threats to national security, and contemporary domestic issues. The theme of Part 1, 1976 Data, was the effect that the Vietnam War has had on United States foreign policy. Those queried were asked to assess America's role in world policy, such as providing economic aid to poorer nations and preventing the destruction of Israel. Given a list of foreign policy questions, respondents were asked to indicate their position and how it was shaped by the Vietnam experience. Questions covered the "domino theory", the Angolan civil war, and the use of United States military power. Those queried were asked to assess possible consequences of the Vietnam War, including policies toward the Third World, and damage to the United States economy. Respondents were also asked to rate the significance of factors that may have prevented the United States from achieving its goal in Vietnam, such as Watergate, the media, and the role of the Soviets and the Chinese. Those queried were asked to assess the role political events and policies such as the Truman Doctrine, the Marshall Plan, the Berlin Airlift, and the 1962 blockade of Cuba played as steps leading to United States involvement in Vietnam. Part 2, 1980 Data, introduced the 1979 Iran hostage crisis and the situation in Afghanistan. Respondents' views were sought on implications of the Afghanistan situation for United States farmers, the 1980 Moscow Olympic Games, foreign military bases, and Soviet foreign policy. Respondents' opinions were sought on current issues in United States foreign relations, such as the Strategic Arms Limitation Talks (SALT), human rights, the United States defense budget, the policy of detente, and policy in the Middle East. Those queried were asked to examine the lessons learned from the Iran hostage crisis, including the role of patience in foreign policy, the overthrow of the shah's regime, and dependence on oil from the Middle East. Part 3, 1984 Data, addressed political undertakings in Lebanon, El Salvador, Grenada, and Nicaragua. Respondents were asked about the implications of events related to the Middle East, including the 1983 truck bombing of United States Marines in Beruit, oil embargoes, and Soviet intentions in the region. Those queried were also asked for their opinions on current issues in American foreign relations, including Soviet-United States arms control negotiations and the defense of Western Europe, including the North Atlantic Treaty Organization (NATO) and the Warsaw Treaty. Views were also sought on recent United States foreign policies, such as opposition to a "nuclear freeze", failure to impose economic sanctions on South Africa for its policy of apartheid, and support of Great Britain after the Argentinian invasion of the Falkland Islands. Part 4, 1988 Data, covered the topics of escorting Kuwait's oil tankers into the Persian Gulf, United States support of the Aquino government in the Philippines, aiding "contra" rebels in Nicaragua, and supporting rebels fighting the government in Afghanistan. Respondents were also asked about the Strategic Defense Initiative (SDI) and the 1987 Intermediate Nuclear Forces (INF) Treaty. Their views were sought on cooperative efforts among nations to end terrorism, famine, the drug trade, and Third World debts. Those queried were asked what influenced their orientations toward foreign affairs, and the reliability of such information. Their views were sought on recent United States foreign policies, including the sale of arms to Iran and Saudi Arabia, the 1986 bombing of Libya, and refusal to invoke the War Powers Act. Other topics included the negative trade balance and Soviet foreign policy goals. Part 5, 1992 Data, focused on the effects of the Persian Gulf War and the collapse of the Soviet Union on United States foreign policy. Respondents were asked for their opinions on the political, economic, and social implications of the end of the Cold War for the United States and its foreign policies. Those queried were asked to evaluate possible reasons for the changes in the Soviet Union and Eastern Europe, including the influence of western media, the failure of communism to provide a satisfactory standard of living, the United States military build-up, and the election of a Polish Pope in 1978. Their views were sought on recent United States foreign policies, including the removal of President Manuel Noriega from power in Panama, the withholding of diplomatic recognition from Croatia and Slovenia, the preservation of NATO, promoting a peace conference to bring Israel and its Arab neighbors to the negotiating table, and creating a trade-free zone with Canada. Part 6, 1996 Data, covered the November 1995 decision by President Bill Clinton to send American troops to Bosnia, and whether vital American interests were at stake. Respondents were asked for their opinions on the possible use of American military forces abroad under a variety of situations. Such scenarios included a Russian invasion of Western Europe, an Iraqi invasion of Saudi Arabia, a Cuban attempt to overthrow Fidel Castro, a North Korean invasion of South Korea, and a civil war in Mexico. Those queried were asked for their opinions on the United States role in the leadership of UN and NATO troops, the values that the United States government should promote, which world problems the United States should contribute to monetarily, and the role of the government in promoting the interests of the disadvantaged. Respondents' views were also sought on recent United States foreign policies, including providing humanitarian aid to Somalia, granting "most favored nation" trade status to China, sending peacekeeping forces to Haiti, supporting NATO expansion, and establishing diplomatic relations with Vietnam. For all parts, background information on respondents includes sex, education, occupation, frequency of world travel, military service record, political party, political orientation, and political involvement.
