Gender and Ethnicity Predictions for California City Council Members and School Board Members, 2010-2023 (ICPSR 209861)

Released/updated on: 2024-10-25
Geographic coverage: California, United States
Time period: 2010-01-01--2023-12-31
To conduct this study, I sourced demographic data from 2010 to 2023 from the California Elections Data Archive (CEDA) for city council members and school board members. The CEDA data provide a full list of candidate names and the number of votes a given candidate received for every city council and school board election. I assigned the gender to each candidate based on the lists of popular male and female names provided by the Social Security Administration. Since the average age of city council members is 46 years old according to the Bureau of Labor Statistics, I compiled a list of popular male and female given names for babies born in the 1960s, 1970s, and 1980s. Then, I automated the gender classification as follows: for example, as “Lisa” is identified as a popular female given name by the Social Security Administration, every candidate whose first name is “Lisa” was assigned “female” in our dataset. For a gender-neutral name that appeared on the lists for both male and female given names, which included “Alex” and “Casey,” I used the following keywords “[first name] [last name] [office type (either “city council” or “school board”)] [name of the city or the school district]” to search for more information about the official’s gender online. My search returned either a picture to help clearly identify the official’s gender and/or an article that refers to the official with gendered pronouns. To identify the ethnicity of each elected official, I used the 2010 Census data and the 23AndMe Surname Discovery Tool. The 2010 Census lists surnames occurring at least 100 times, and it includes self-reported ethnicity data for individuals with a given surname. Similarly, the 23AndMe Surname Discovery Tool gives the percentage of individuals with the given surname who identify as each of four different ethnicity groups: Hispanic, White, Asian/Pacific Islander, and Black based on the 2010 US Census data. For surnames that did not appear on either the 2010 Census data or the 23AndMe Surname Discovery Tool, I used Python’s Ethnicolr library, which bases its prediction of ethnicity using either both first and last name or just the last name on the US census data (2000 and 2010), the Florida voting registration data, and the Wikipedia data.

Law Enforcement Management and Administrative Statistics (LEMAS), 2020 (ICPSR 38651)

Released/updated on: 2023-03-07
Geographic coverage: United States
Time period: 2020-01-01--2020-12-31
The Law Enforcement Management and Administrative Statistics (LEMAS) survey collects data from a nationally representative sample of general-purpose agencies (i.e., local and county police departments, sheriffs' offices, and primary state police agencies). The 2020 LEMAS sample design called for the survey questionnaire to be sent to 3,499 general purpose law enforcement agencies, including 2,631 local and county police departments, 819 sheriffs' offices, and the 49 primary state police departments (Hawaii does not have a primary state police agency). The design called for all agencies employing 100 or more full-time equivalent sworn personnel to be included with certainty (self-representing), and for smaller agencies to be sampled from strata based on number of full-time equivalent sworn officers and type of agency. A total of 37 local police departments were determined to be out-of-scope for the survey because they had closed, had less than one full-time equivalent sworn officer, had contracted out their services with another law enforcement agency, or only had special enforcement responsibilities. The final mail out total of 3,462 agencies included 2,611 local police departments, 802 sheriffs' offices, and the 49 state agencies.

Time period: 1978-01-01--1994-12-31
Data in this collection examine the processing of federal offenders. The Cases Terminated files (Parts 1-3 and 25-28) contain information about defendants in criminal cases filed in the United States Federal District Court and terminated in the calendar years indicated. Defendants in criminal cases may either be individuals or corporations, and there is one record for each defendant in each case terminated. Information on court proceedings, date the case was filed, date the case was terminated, most serious charge, and reason for termination is included. The Docket and Reporting System files (Parts 4-7, 31-34, and 42) include information on suspects in investigative matters that took an hour or more of a United States Attorney's time with one of the following outcomes: (1) the United States Attorney declined to prosecute, (2) the case was filed in Federal District Court, or (3) the matter was disposed by a United States magistrate. Codes for each disposition and change of status are also provided. The Pretrial Services data (Parts 8, 22, 43, and 47) present variables on the circuit, district, and office where the defendant was charged, type of action, year of birth and sex of the defendant, major offense charge, and results of initial and detention hearings. The Parole Decisions data (Part 9) contain information from various parole hearings such as court date, appeal action, reopening decision, sentence, severity of sentence, offense, and race and ethnicity of the defendant. The Offenders Under Supervision files (Parts 15-16 and 37-40) focus on convicted offenders sentenced to probation supervision and federal prisoners released to parole supervision. The Federal Prisoner files (Parts 18 and 20) supply data on when an offender entered and was released from confinement, as well as the amount of time served for any given offense. The Administrative Office of the United States Courts data files (Parts 44, 52, and 53) contain records of defendants in criminal cases filed in Federal District Court and terminated in the calendar years indicated. There is one record for each defendant in each case. Variables include the date the case was filed, offense level, AO (Administrative Office) codes, and disposition date. The Bureau of Prisons data (both the Master and Detail files, Parts 45, 46, and 54-57 -- formerly known as the Federal Prisoner files) contain records of sentenced prisoners admitted to or released from federal prison during 1992-1994. These files consist of separate records for each prisoner's commitment to federal prison, and for each sentence imposed on a prisoner for a given commitment to federal prison. The Central System (CS) and Central Charge (CC) files of the Executive Office for United States Attorneys (EOUSA) include information about suspects in criminal matters and defendants in criminal cases in 1993-1994. Each defendant in a criminal matter has a master Central System record (Parts 50 and 51) and may have one or more Central Charge records (Parts 48 and 49). The Federal Probation/Supervision Data files (Parts 58 and 59) provide information on supervision procedures and the sequence of events and proceedings in 1992-1994 from the time a case was opened for supervision until the case was terminated. These include reports of parole violations, transfers of supervision to other districts, and case removals due to, for example, rearrest or hospitalization. The Sentencing Commission data (Parts 60 and 61) contain information on federal criminal cases sentenced in 1992-1994 under the Sentencing Guidelines and Policy Statements of the Sentencing Reform Act of 1984.

National Juvenile Court Data Archive, United States, 1985-2019 (ICPSR 38418)

Released/updated on: 2022-07-28
Geographic coverage: United States
Time period: 1985-01-01--2019-12-31

The National Juvenile Court Data Archive houses over 15 million automated records of cases handled by courts with juvenile jurisdiction. Although some states' data contain traffic and dependency cases, the majority are delinquency and status offense records. The collection itself dates back to the 1920s when it was under the Children's Bureau, however in 1974 the Office of Juvenile Justice and Delinquency Prevention (OJJDP), within the U.S. Department of Justice assumed responsibility for the work of promoting access to automated juvenile court data sets for juvenile justice research and policymaking efforts.

The Archive contains the most detailed information available on juveniles involved in the juvenile justice system and on the activities of U.S. juvenile courts. The Archive houses a sizable collection of automated juvenile court data files that not only support the national estimates but also support the study of a wide range of national and subnational juvenile justice issues. Designed to facilitate research on the juvenile justice system, the Archive's data files are available to policy-makers, researchers, students, and the public. The data have been used to explore a broad range of topics, from investigating the effectiveness of juvenile court programs and examining policy developments in individual jurisdictions, to monitoring the impact of legislative changes, and guiding juvenile justice system reform.

Law Enforcement Management and Administrative Statistics Body-Worn Camera Supplement (LEMAS-BWCS), 2016 (ICPSR 37302)

Released/updated on: 2019-06-20
Geographic coverage: United States
Time period: 2015-01-01--2016-12-31
Beginning in 2016, the Law Enforcement Management and Administrative Statistics (LEMAS) survey adopted a core and supplement structure. The LEMAS core has been conducted every 3 to 4 years since 1987 with approximately 3,200 local, county and state law enforcement agencies across the United States. Due to the breadth of the survey, detailed analysis of any specific law enforcement topic cannot be done with the LEMAS core. The LEMAS supplements are designed to fill this void by allowing for a more comprehensive examination on a key topic in law enforcement and are administered in between core years. The 2016 LEMAS Body-Worn Camera Supplement (LEMAS-BWCS) is the first supplement administered under the new structure.

Law Enforcement Agency Roster (LEAR), 2016 (ICPSR 36697)

Released/updated on: 2017-04-05
Geographic coverage: United States
Time period: 2015-01-01--2016-12-31
In the past several years, BJS has made efforts to develop a national roster of publicly funded law enforcement agencies. The Census of State and Local Law Enforcement Agencies (CSLLEA) represents the core of the BJS's law enforcement statistics program, and is currently used as the primary universe for all BJS law enforcement collections. The CSLLEA was last conducted in 2014 but encountered data collection issues. Since the last law enforcement universe list was the 2008 CSLLEA, BJS decided further work was needed to have a reliable and complete roster of law enforcement agencies. Using the 2008 and 2014 CSLLEA universe as the base, the LEAR integrated multiple datasets in an effort to compile a complete list of active general purpose law enforcement agencies. The goal of the LEAR was to serve as the universe list for which the Law Enforcement Management and Administrative Statistics (LEMAS) core and supplement samples could be pulled. The 2016 LEAR contains a census of 15,810 general purpose law enforcement agencies, including 12,695 local and county police departments, 3,066 sheriffs' offices and 49 primary state police departments. Staffing size from multiple datasets has also been merged into the LEAR file.

National Spinal Cord Injury Statistical Center (ICPSR 36567)

Released/updated on: 2016-09-15
Geographic coverage: United States

The National Spinal Cord Injury Statistical Center (NSCISC) is operated by the University of Alabama at Birmingham Department of Physical Medicine and Rehabilitation through funding from the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR). NSCISC supports and directs the collection, management, and analysis of the world's largest and longest spinal cord injury (SCI) research database. Organizationally, NSCISC is currently at the hub of a network of 14 NIDILRR-sponsored and 5 subcontract-funded Spinal Cord Injury Model Systems located at major medical centers throughout the United States. In addition to maintaining the national SCI database, NSCISC personnel conduct ongoing, database-oriented research. NSCISC produces annuals reports and "Facts and Figures at a Glance" which can be accessed here.

The National Spinal Cord Injury Database has been in existence since 1973 and captures data from an estimated 6% of new SCI cases in the U.S. Since its inception, 28 federally funded SCI Model Systems have contributed data to the National SCI Database. As of March 2016, the database contained information on 31,645 persons who sustained traumatic spinal cord injuries. To assure comparability of data acquired by personnel in various centers, rigid scientific criteria have been established for the collection, management, and analysis of information entered into the database. National Spinal Cord Injury Statistical Center staff has also developed quality control procedures that further enhance the reliability and validity of the database.

Within the scope of the Spinal Cord Injury Model System program, the purposes of the National SCI Database are as follows:

  1. to study the longitudinal course of traumatic SCI and factors that affect that course;
  2. to identify and evaluate trends over time in etiology, demographic, and injury severity characteristics of persons who incur a SCI;
  3. to identify and evaluate trends over time in health services delivery and treatment outcomes for persons with SCI;
  4. to establish expected rehabilitation treatment outcomes for persons with SCI; and
  5. to facilitate other research such as the identification of potential persons for enrollment in appropriate SCI clinical trials and research projects or as a springboard to population-based studies.

The Database, however, is not intended to study the effectiveness of model systems care as compared to other systems of health care delivery. It is also not by itself intended to gather and maintain population-based data on spinal cord injuries.

Law Enforcement Management and Administrative Statistics (LEMAS), 2013 (ICPSR 36164)

Released/updated on: 2015-09-22
Geographic coverage: United States
Time period: 2013-01-01--2013-12-31
The Law Enforcement Management and Administrative Statistics (LEMAS) survey collects data from a nationally representative sample of state and local law enforcement agencies in the United States. Although the data collection instrument (see page 150 of the codebook) uses the year 2012 for the title, most questions have a reference date of January 1, 2013. For this reason, the study title uses the year 2013. The 2013 LEMAS sample design called for the survey questionnaire to be sent to 3,336 general purpose state and local law enforcement agencies including 2,353 local police departments, 933 sheriffs' offices, and the 50 primary state law enforcement agencies. The design called for all agencies employing 100 or sworn personnel to be included with certainty (self-representing) and for smaller agencies to be sampled from strata base on number of officers employed. A total of 26 local police departments were determined to be out-of-scope for the survey because they were closed, outsourced, or operating on a part-time basis. A total of 38 sheriffs' offices were excluded from the survey because they had no primary law enforcement jurisdiction. The final mailout total of 3,272 agencies included 2,327 local police departments, 895 sheriffs' offices, and the 50 state agencies.

The purpose of the study was to determine how Compstat programs were being implemented across the United States by examining the diffusion of Compstat and factors associated with its implementation. Another goal of the study was to assess the impact of Compstat on line or patrol officers at the bottom of the police organization. The researchers administered a national survey on Compstat and problem solving in police agencies (Part 1) by mail to all 515 American police agencies with over 100 sworn police officers, and to a random sample of 100 agencies with between 50 and 100 sworn officers. The researchers received a total of 530 completed surveys (Part 1) between June 1999 and April 2000. The researchers distributed an anonymous, voluntary, and self-administered survey (Part 2) between December 2000 and May 2001 to a total of 450 patrol officers at three police departments -- Lowell, Massachusetts (LPD), Minneapolis, Minnesota (MPD), and Newark, New Jersey (NPD). The Compstat Survey (Part 1) contains a total of 321 variables pertaining to executive views and departmental policy, organizational features and technology, and comments about problem solving in police agencies. The Line Officer Survey (Part 2) contains a total of 85 variables pertaining to the patrol officers' involvement in Compstat-generated activities, their motivation to participate in them, and their views on these activities.

American Voting Behavior: Presidential Elections from 1952-1980 (ICPSR 7581)

Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1952-01-01--1980-12-31
This instructional package includes a student manual containing six exercises, an instructor's guide, and four subsets of data required for use in conjunction with the manual's exercises. The package's major purpose is to enable students to examine certain substantive questions about electoral behavior through analysis of political survey data. The manual avoids instruction in methodology, per se, hence the student is taken no further than the analysis of straightforward variables in percentagized tables with and without controls, and is introduced to epsilon, the percentage difference measures based on 2 X 2 tables, but offered no elaborate discussion of measures of association. The six structured exercises introduce the basic analytic techniques necessary for coping with survey data in the expectation that the students will then move on to their own topics. The datasets were designed to be both substantively and analytically interesting, as students are forced continually to make choices and judgments about which variables to use and how to combine code categories. Beyond this, the exercises serve a more complex purpose: to help the student gain a better understanding of the existing scholarly literature by going through steps similar to those of the original analysts. In some instances, the students can readily appreciate how close their work is to the analysis in assigned reading. The instructor's guide has two purposes: first, to help instructors use the student manual effectively, and second, to suggest various ways to depart from the six exercises and to develop essentially new manuals. The subsets (Parts 1-4) contain data from every presidential election survey that was conducted by the Survey Research Center (SRC) and Center for Political Studies (CPS) (at the University of Michigan) from 1952 to 1980. Part 4 contains an extensive set of variables drawn exclusively from the CPS's AMERICAN NATIONAL ELECTION STUDY, 1980 (ICPSR 7763). This is the only deck needed to complete the exercises in Exercises l-5. Part 1 includes small sets of comparable variables from each SRC/CPS presidential election study from 1952-1972. The variables in these decks were selected with the intention of providing students with a range of interesting possibilities for original research topics for term papers. Part 2 includes variables and respondents from panel surveys contained in AMERICAN NATIONAL ELECTION SERIES: 1972, 1974, 1976 (ICPSR 7607). This dataset may be used with Exercise 6. Supplementing the panel file is the data in Part 3, based on the cross-section survey, AMERICAN NATIONAL ELECTION STUDY, 1976 (7381). It repeats the variables from the 1976 component of the panel, with a much larger N. The AMERICAN NATIONAL ELECTION STUDY, 1976 (7381) may be used independently, as with the AMERICAN NATIONAL ELECTION STUDY, 1980 (ICPSR 7763), or it may be used in exercises comparing cross-section with panel data. Data used for the exercises were made available by ICPSR. The major analyses of these data have appeared in two publications: (1) University of Michigan. Survey Research Center. THE AMERICAN VOTER. New York, NY: Wiley, 1960, and (2) Campbell, Angus, Philip Converse, Warren Miller, and Donald Stokes. ELECTIONS AND THE POLITICAL ORDER. New York, NY: Wiley, 1966.
