Released/updated on: 2007-09-27
Geographic coverage: North Carolina, Vermont, United States, Tennessee, Arkansas, Utah, West Virginia, Colorado, Missouri, Virgin Islands of the United States, Phoenix, Arizona, Las Vegas, Nevada, District of Columbia, Montana, Sacramento, Seattle, Hawaii, Minnesota, California, Florida, Delaware, New York (state), New Jersey, Michigan, Pennsylvania, Mississippi, Iowa, Illinois, Connecticut, Maryland
Time period: 2002-10-01--2004-04-01
This trends and best practices evaluation geared toward motor vehicle theft prevention with a particular focus on the Watch Your Car (WYC) program was conducted between October 2002 and March 2004. On-site and telephone interviews were conducted with administrators from 11 of 13 WYC member states. Surveys were mailed to the administrators of auto theft prevention programs in 36 non-WYC states and the 10 cities with the highest motor vehicle theft rates. Completed surveys were returned from 16 non-WYC states and five of the high auto theft rate cities. Part 1, the survey for Watch Your Car (WYC) program members, includes questions about how respondents learned about the WYC program, their WYC related program activities, the outcomes of their program, ways in which they might have done things differently if given the opportunity, and summary questions that asked WYC program administrators for their opinions about various aspects of the overall WYC program. The survey for the nonmember states, Part 2, and cities, Part 3, collected information about motor vehicle theft prevention within the respondent's state or city and asked questions about the respondent's knowledge of, and opinions about, the Watch Your Car program.

Developing a Problem-Oriented Policing Model in Ada County, Idaho, 1997-1998 (ICPSR 2654)

Released/updated on: 2005-11-04
Geographic coverage: United States, Idaho
Time period: 1997-01-01--1998-01-01
To explore the idea of community policing and to get an understanding of citizens' policing needs, representatives from the Ada County Sheriff's Office and Boise State University formed a research partnership and conducted surveys of county residents and sheriff's deputies. The county-wide survey of residents (Part 1) was designed to enhance the sheriff's current community policing program and to assist in the deployment of community policing officers by measuring citizens' perceptions and fear of crime, perceptions of deputies, knowledge of sheriff's services, and support for community policing. Questions in the citizen survey focused on feelings of safety in Ada County, such as perception of drugs, gangs, safety of youth, and safety at night, satisfaction with the Sheriff's Office, including ratings of the friendliness and fairness of the department and how well deputies and citizens worked together, attitudes regarding community-oriented policing, such as whether this type of policing would be a good use of resources and would reduce crime, and neighborhood problems, including how problematic auto theft, vandalism, physical decay, and excessive noise were for citizens. Other questions were asked regarding the sheriff's deputy website, including whether citizens would like the site to post current crime reports, and whether the site should have more information about the jail. Respondents were also queried about their encounters with police, including their ratings of recent services they received for traffic violations, requests for service, and visits to the jail, and familiarity with several programs, such as the inmate substance abuse program and the employee robbery prevention program. Demographic variables in the citizen survey include ethnicity, gender, level of schooling, occupation, income, age, and length of time residing in Ada County. The second survey (Part 2), created for the sheriff's deputies, used questions from the citizen survey about the Sheriff's Office service needs. Deputies were asked to respond to questions in the way they thought that citizens would answer these same questions in the citizen survey. The purpose was to investigate the extent to which sheriff's deputies' attitudes mirrored citizens' attitudes about the quality of service.

Empirical Investigation of "Going to Scale" in Drug Interventions in the United States, 1990, 2003 (ICPSR 26101)

Released/updated on: 2009-08-26
Geographic coverage: United States
Despite a growing consensus among scholars that substance abuse treatment is effective in reducing offending, strict eligibility rules have limited the impact of current models of therapeutic jurisprudence on public safety. This research effort was aimed at providing policy makers some guidance on whether expanding this model to more drug-involved offenders is cost-beneficial. Since data needed for providing evidence-based analysis of this issue were not readily available, micro-level data from three nationally representative sources were used to construct a 40,320 case synthetic dataset -- defined using population profiles rather than sampled observation -- that was used to estimate the benefits of going to scale in treating drug involved offenders. The principal investigators combined information from the NATIONAL SURVEY ON DRUG USE AND HEALTH, 2003 (ICPSR 4138) and the ARRESTEE DRUG ABUSE MONITORING (ADAM) PROGRAM IN THE UNITED STATES, 2003 (ICPSR 4020) to estimate the likelihood of drug addiction or dependence problems and develop nationally representative prevalence estimates. They used information in the DRUG ABUSE TREATMENT OUTCOME STUDY (DATOS), 1991-1994 (ICPSR 2258) to compute expected crime reducing benefits of treating various types of drug involved offenders under four different treatment modalities. The project computed expected crime reducing benefits that were conditional on treatment modality as well as arrestee attributes and risk of drug dependence or abuse. Moreover, the principal investigators obtained estimates of crime reducing benefits for all crimes as well as select sub-types. Variables include age, race, gender, offense, history of violence, history of treatment, co-occurring alcohol problem, criminal justice system status, geographic location, arrest history, and a total of 134 prevalence and treatment effect estimates and variances.

Enhancing the Research Partnership Between the Albany Police Department and the Finn Institute, 2005-2016 (ICPSR 37820)

Released/updated on: 2020-12-16
Geographic coverage: United States, New York (state), Albany (New York)
Time period: 2005-01-01--2016-01-01

The Finn Institute is an independent, not-for-profit corporation that conducts research on matters of public safety and security. The project provided for steps that would strengthen and enhance an existing police-researcher partnership, focused around analyses of proactive policing. As part of a research partnership with the Albany Police Department (APD) and the Finn Institute, this study was oriented around a basic research question: can proactive policing be conducted more efficiently, in the sense that a better ratio of high-value to lower-value stops is achieved, such that the trade-off between crime reduction and police community relations is mitigated.

Albany Resident Survey Dataset (DS1) unit of analysis was individuals. Variables include neighborhood crime and disorder, legitimacy and satisfaction with police service, and direct and vicarious experience with stop and perceptions of stops as a problem. Demographic variables include age, race, education, employment, marital status, and household count.

Management of "Smart Stops" Dataset (DS2) unit of analysis was investigatory stops; variables include records of individual stops, the month and year of the stop, whether the location of the stop was a high-crime location, whether the person stopped (or any of the persons stopped, if multiple people were stopped at one time) were high-risk, and whether the stop resulted in an arrest.

Trends in Proactive Policing Dataset (DS3) unit of analysis was APD officers. Variables include number of stops per quarter; variables include demographics such as officer characteristics such as their assignments, length of service, and gender.

Evaluation of CeaseFire, a Chicago-based Violence Prevention Program, 1991-2007 (ICPSR 23880)

Released/updated on: 2015-02-25
Geographic coverage: United States, Chicago, Illinois
Time period: 1991-01-01--2006-12-01, 1998-02-01--2006-04-01, 2006-05-01--2007-08-01, 2006-09-01--2007-02-01, 2007-04-05--2007-07-19

This study evaluated CeaseFire, a program of the Chicago Project for Violence Prevention. The evaluation had both outcome and process components.

The outcome evaluation assessed the program's impact on shootings and killings in selected CeaseFire sites. Two types of crime data were compiled by the research team: Time Series Data (Dataset 1) and Shooting Incident Data (Dataset 2). Dataset 1 is comprised of aggregate month/year data on all shooting, gun murder, and persons shot incidents reported to Chicago police for CeaseFire's target beats and matched sets of comparison beats between January 1991 and December 2006, resulting in 1,332 observations. Dataset 2 consists of data on 4,828 shootings that were reported in CeaseFire's targeted police beats and in a matched set of comparison beats for two-year periods before and after the implementation of the program (February 1998 to April 2006).

The process evaluation involved assessing the program's operations and effectiveness. Researchers surveyed three groups of CeaseFire program stakeholders: employees, representatives of collaborating organizations, and clients.

The three sets of employee survey data examine such topics as their level of involvement with clients and CeaseFire activities, their assessments of their clients' problems, and their satisfaction with training and management practices. A total of 154 employees were surveyed: 23 outreach supervisors (Dataset 3), 78 outreach workers (Dataset 4), and 53 violence interrupters (Dataset 5).

The six sets of collaborating organization representatives data examine such topics as their level of familiarity and contact with the CeaseFire program, their opinions of CeaseFire clients, and their assessments of the costs and benefits of being involved with CeaseFire. A total of 230 representatives were surveyed: 20 business representatives (Dataset 6), 45 clergy representatives (Dataset 7), 26 community representatives (Dataset 8), 35 police representatives (Dataset 9), 36 school representatives (Dataset 10), and 68 service organization representatives (Dataset 11).

The Client Survey Data (Dataset 12) examine such topics as clients' involvement in the CeaseFire program, their satisfaction with aspects of life, and their opinions regarding the role of guns in neighborhood life. A total of 297 clients were interviewed.

Evaluation of the Agriculture Crime Technology Information and Operation Network (ACTION) in Nine Counties in California, 2004-2005 (ICPSR 4686)

Released/updated on: 2009-05-01
Geographic coverage: United States, California
Time period: 2004-01-01--2005-01-01
The Urban Institute and Florida State University multidisciplinary research team employed a multimethod approach to evaluate the Agricultural Crime, Technology, Information, and Operations Network (ACTION) project. The goal of the research was to provide policymakers, practitioners, program developers, and funders with empirically-based information about whether ACTION works. Two paper-and-pencil, self-administered surveys -- one in fall 2004 and the second in fall 2005 -- were sent to samples of farmers in the nine ACTION counties in California. The researchers identified farms using lists provided by Agricultural Commissioners in each county. The survey instruments asked farmers about experiences with agricultural crime victimization during the 12 months prior to the survey. It also asked questions about characteristics of their farm operations and the activities that they take to prevent agricultural crime. Advance notice of the study was given to farmers through the use of postcards, then surveys were sent to farmers in three waves at one-month intervals, with the second and third waves targeting nonrespondents. The Fall 2004 Agricultural Crime Survey (Part 1) contains data on 823 respondents (farms) and the Fall 2005 Agricultural Crime Survey (Part 2) contains data on 818 respondents (farms).

Evaluation of the Tribal Strategies Against Violence (TSAV) Initiative in Four Tribal Sites in the United States, 1995-1999 (ICPSR 4080)

Released/updated on: 2005-03-15
Geographic coverage: Montana, United States, Oklahoma, North Dakota, Michigan
Time period: 1995-01-01--1999-01-01
This study evaluated the Tribal Strategies Against Violence (TSAV) Initiative. The TSAV was a federal-tribal partnership, lasting from 1995 to 1999, designed to develop comprehensive strategies in tribal communities to reduce crime, violence, and substance abuse. This study involved four of the seven TSAV sites: the Chickasaw Nation in Oklahoma, Fort Peck Assiniboine and Sioux Tribes in Montana, the Grand Traverse Band of Ottawa and Chippewa Indians in Michigan, and the Turtle Mountain Band of Chippewa Indians in North Dakota. A survey of TSAV stakeholders at the four sites was conducted in the summer and fall of 1999. The objectives of the survey were to gauge TSAV stakeholders' perceptions about the following: (1) the serious crime, violence, and quality of life issues in each community and the extent to which the local TSAV initiative had addressed those issues, (2) the intent and ultimate outcomes of the TSAV program, (3) obstacles to successful implementation of TSAV activities, and (4) decision-making processes used in planning and implementing TSAV locally. Offense data were also gathered at the Fort Peck site for 1995 to 1998 and at the Grand Traverse Band site for 1997 to 1999.

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

Released/updated on: 2005-11-04
Geographic coverage: United States
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.

Examination of South Carolina's Sex Offender Registration and Notification (SORN) Policy in Reducing Sexual Violence, 1990-2005 (ICPSR 31502)

Released/updated on: 2015-07-30
Geographic coverage: United States, South Carolina
Time period: 1990-01-01--2005-01-01

This study examined the effects of comprehensive registration and community notification policies on rates of sexual violence in South Carolina. Specifically, it proposed to (1) evaluate whether broad sex offender registration and notification policies have reduced recidivism or deterred new sexual offenses, (2) examine whether unintended effects of broad registration and notification policies occurred, and (3) focus on the effects of registration and notification as it pertained to offenses committed by adults. The study examined whether the introduction of sex offender registration and notification laws in South Carolina were associated with reductions in sexual crimes and, if so, whether this reduction could be attributed to an actual reduction in sexual violence and/or recidivism (i.e., an intended effect) or to changes in criminal judicial processing of individuals for registry crimes (i.e., an unintended effect).

Specific study aims included examining whether: (1) South Carolina registration and notification policies had the intended effect of preventing first time sexual offending; (2) South Carolina registration and notification policies had the intended effect of reducing sexual recidivism for known sex offenders; and (3) South Carolina registration and notification policies had the unintended effect of reducing the probability that individuals who committed sexual crimes would be prosecuted or convicted for such crimes. In addition to these primary aims, the researchers also investigated (4) registration violations (e.g., failure to register) were associated with sexual or general recidivism.

Measuring Perceptions of Appropriate Prison Sentences in the United States, 2000 (ICPSR 3988)

Released/updated on: 2006-03-30
Geographic coverage: United States
Time period: 2000-05-16--2000-08-08
This study examined the public's preferences regarding sentencing and parole of criminal offenders. It also investigated the public's willingness to pay for particular crime prevention and control strategies and tested new methods for gathering this kind of information from the public. This involved asking the public to respond to a series of crime vignettes that involved constrained choice. The study consisted of a telephone survey of 1,300 adult respondents conducted in 2000 in the United States. Following a review by a panel of experts and extensive pretesting, the final instrument was programmed for computer-assisted telephone interviews (CATI). The questionnaire specifically focused on: (1) the attitudes of the public on issues such as the number of police on the street, civil rights of minority groups, and the legal rights of people accused of serious crimes, (2) the randomized evaluation of preferred sentencing alternatives for eight different crime scenarios, (3) making parole decisions in a constrained choice setting by assuming that there is only enough space for one of two offenders, (4) the underlying factors that motivate the public's parole decisions, and (5) respondents' willingness to pay for various crime prevention strategies.

Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

This data collection represents an experimental micro-level geospatial crime prevention strategy that attempted to interrupt the near repeat (NR) pattern in residential burglary by creating a NR space-time high risk zone around residential burglaries as they occurred and then using uniformed volunteers to notify residents of their increased risk and provide burglary prevention tips. The research used a randomized controlled trial to test whether high risk zones that received the notification had fewer subsequent burglaries than those that did not. In addition, two surveys were administered to gauge the impact of the program, one of residents of the treatment areas and one of treatment providers.

The collection contains 6 Stata datasets:

Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

This research expanded on offenders' decisions whether or not to offend by having explored a range of alternatives within the "not offending" category, using a framework derived from the concept of crime displacement. Decision trees were employed to analyze the multi-staged decision-making processes of criminals who are blocked from offending due to a situational crime control or prevention measure. The researchers were interested in determining how offenders evaluated displacement options as available alternatives. The data were collected through face-to-face interviews with 200 adult offenders, either in jail or on probation under the authority of the Texas Department of Criminal Justice, from 14 counties. Qualitative data collected as part of this study's methodology are not included as part of the data collection at this time.

Three datasets are included as part of this collection:

This study was a process evaluation of the Comprehensive Communities Program (CCP) intended to develop insights into how community approaches to crime and drug abuse prevention and control evolved, to track how each site implemented its comprehensive strategy, to determine the influence of preexisting ecological, social, economic, and political factors on implementation, and to monitor the evolution of strategies and projects over time. Intensive evaluations were done at six CCP sites: Baltimore, Maryland; Boston, Massachusetts; Columbia, South Carolina; Fort Worth, Texas; Salt Lake City, Utah; and Seattle, Washington. Less intensive evaluations were done at six other CCP sites: Gary, Indiana; Hartford, Connecticut; Wichita, Kansas; the Denver, Colorado, metropolitan area; the Atlanta, Georgia, metropolitan area; and the East Bay area of northern California. At all 12 sites, 2 waves of a Coalition Survey (Parts 1 and 2) were sent to everyone who participated in CCP. Likewise, 2 waves of the Community Policing Survey (Parts 3 and 4) were sent to the police chiefs of all 12 sites. Finally, all 12 sites were visited by researchers at least once (Parts 5 to 13). Variables found in this data collection include problems facing the communities, the implementation of CCP programs, the use of community policing, and the effectiveness of the CCP programs and community policing efforts.

Within the past fifteen years, policymakers across the country have increasingly supported criminal justice reforms designed to reduce the scope of mass incarceration in favor of less costly, more evidence-based approaches to preventing and responding to crime. One of the primary reform efforts is the Justice Reinvestment Initiative (JRI), a public-private partnership through which state governments work to diagnose the primary drivers of their state incarceration rates, reform their sentencing policies to send fewer nonviolent offenders to prison, and reinvest the saved money that used to go into prisons into alternatives to incarceration, instead.

This mixed-methods study sought to assess public opinion about the justice reinvestment paradigm of reform and to determine whether exposure to racialized and race-neutral cues affects people's willingness to allocate money into criminal justice institutions versus community-based social services in order to reduce and prevent crime.

Reducing Disorder, Fear, and Crime in Public Housing: Evaluation of a Drug-Crime Elimination Program in Spokane, Washington, 1992-1995 (ICPSR 2628)

Released/updated on: 2006-03-30
Geographic coverage: United States, Spokane, Washington
Time period: 1992-01-01--1995-12-31
Established in 1994, Project ROAR (Reclaiming Our Area Residences) is a public housing drug-crime elimination program sponsored by the Spokane Police Department and the Spokane Housing Authority. This study was undertaken to examine and evaluate the effects and outcomes of Project ROAR as it was implemented in the Parsons' Public Housing Complex, located in downtown Spokane, Washington. In addition, the study sought to determine to what extent the project as implemented reflected Project ROAR as originally conceived, and whether Project ROAR could be considered a comprehensive community policing crime prevention program. Further, the study attempted to determine what effects this collaborative anti-crime program might have on: (1) residents' perceptions of the quality of their neighborhood life, including perceptions of neighborhood inhabitants, satisfaction with their neighborhood, fear of crime, and neighborhood physical and social disorder, (2) objective measures of physical and social disorder, (3) levels of neighborhood crime, and (4) subjective perceptions of the level and quality of policing services. To assess the implementation and short-term impacts of Project ROAR, data were collected from various sources. First, four waves of face-to-face interviews were conducted with Parsons' Public Housing residents at approximately six-month intervals: April 1994, December 1994, May 1995, and November 1995 (Part 1, Public Housing Residents Survey Data). Information collected from interviews with the Parsons' residents focused on their involvement with Project ROAR, community block watches, and tenant councils. Residents commented on whether there had been any changes in the level of police presence, drug-related crimes, prostitution, or any other physical or social changes in their neighborhood since the inception of Project ROAR. Residents were asked to rate their satisfaction with the housing complex, the neighborhood, the Spokane Police Department, the number of police present in the neighborhood, and the level of police service. Residents were also asked if they had been the victim of any crimes and to rate their level of fear of crime in the complex during the day and night, pre- and post-Project ROAR. The gender and age of each survey participant was also recorded. The second source of data was a city-wide survey mailed to the residents of Spokane (Part 2, Spokane Citizens Survey Data). Information collected from the survey includes demographics on ethnicity, gender, age, highest level of education, present occupation, and family income. The city residents were also asked to assess the level of police service, the number of police present in their neighborhood, the helpfulness of neighbors, whether they felt safe alone in their neighborhood, and overall satisfaction with their neighborhood. Third, a block-level physical and social disorder inventory was taken in April 1994, October 1994, April 1994, and October 1995 (Part 3, Neighborhood Inventory Data). The sex, age, and behavior of the first ten people observed during the inventory period were recorded, as well as the number of people observed loitering. Other observations made included the number of panhandlers, prostitutes, open drug sales, and displays of public drunkenness. The number of residential and commercial properties, restaurants, bars, office buildings, empty lots, unboarded and boarded abandoned buildings, potholes, barriers (walls or fences), abandoned cars, and for-sale signs, along with the amount of graffiti on public and private properties and the amount of litter and broken glass observed in each neighborhood, completed the inventory data. Finally, crime reports were collected from the Spokane Police Department's Crime Analysis Unit (Part 4, Disaggregated Crime Data, and Part 5, Aggregated Crime Data). These data contain monthly counts of robberies and burglaries for the public housing neighborhood, a constructed controlled comparison neighborhood, and the city of Spokane for the period January 1, 1992, through December 31, 1995.

Reducing Violence in Communities: An In-Depth Study of Efforts in Durham, NC and Minneapolis, MN, 2010-2022 (ICPSR 38691)

Released/updated on: 2024-10-30
Geographic coverage: North Carolina, Minneapolis, United States, Minnesota, Durham
Time period: 2010-01-01--2022-01-01

Recognizing that violence can be an intractable problem in many communities and that there are numerous approaches to both an immediate violence problem and the range of root causes behind violence, the National Institute of Justice funded an investigation into what factors underlie violence and efforts being implemented to address those factors and potentially reduce violence at the community level. In this mixed methods study, the RAND Corporation drew on data from key informant interviews, community surveys, administrative data, and geographic data to examine specific factors that contribute to violence, as well as a range of anti-violence efforts that have been used to address violence levels in two U.S. communities: the Bullseye area of Durham, North Carolina, and the Northside (North Minneapolis) neighborhood of Minneapolis, Minnesota. Specifically, the research project aimed to answer the following questions:

  1. What are community level factors that can contribute to persistent violence?
  2. What are the key factors in both cities that distinguish high violent crime areas compared to low violent crime areas?

This collection contains final analytic datasets for Durham (DS1) and Minneapolis (DS2), violent crime rate data (DS3), community survey data for Durham (DS4) and Minneapolis (DS5), and multiple datasets containing community-level contextual factors from the American Community Survey (ACS) and geographical data from the U.S. Census Bureau (2009-2018) that were used to build the final analytic datasets (DS6-DS11). Qualitative data from key informant interviews and GIS data are not available for download at this time. Access to Durham and Minneapolis community survey data is restricted.

Valuation of Specific Crime Rates in the United States, 1980 and 1990 (ICPSR 3161)

Released/updated on: 2006-01-18
Geographic coverage: United States
This project was designed to isolate the effects that individual crimes have on wage rates and housing prices, as gauged by individuals' and households' decisionmaking preferences changing over time. Additionally, this project sought to compute a dollar value that individuals would bear in their wages and housing costs to reduce the rates of specific crimes. The study used multiple decades of information obtained from counties across the United States to create a panel dataset. This approach was designed to compensate for the problem of collinearity by tracking how housing and occupation choices within particular locations changed over the decade considering all amenities or disamenities, including specific crime rates. Census data were obtained for this project from the Integrated Public Use Microdata Series (IPUMS) constructed by Ruggles and Sobek (1997). Crime data were obtained from the Federal Bureau of Investigation's Uniform Crime Reports (UCR). Other data were collected from the American Chamber of Commerce Researchers Association, County and City Data Book, National Oceanic and Atmospheric Administration, and Environmental Protection Agency. Independent variables for the Wages Data (Part 1) include years of education, school enrollment, sex, ability to speak English well, race, veteran status, employment status, and occupation and industry. Independent variables for the Housing Data (Part 2) include number of bedrooms, number of other rooms, building age, whether unit was a condominium or detached single-family house, acreage, and whether the unit had a kitchen, plumbing, public sewers, and water service. Both files include the following variables as separating factors: census geographic division, cost-of-living index, percentage unemployed, percentage vacant housing, labor force employed in manufacturing, living near a coastline, living or working in the central city, per capita local taxes, per capita intergovernmental revenue, per capita property taxes, population density, and commute time to work. Lastly, the following variables measured amenities or disamenities: average precipitation, temperature, windspeed, sunshine, humidity, teacher-pupil ratio, number of Superfund sites, total suspended particulate in air, and rates of murder, rape, robbery, aggravated assault, burglary, larceny, auto theft, violent crimes, and property crimes.
