    United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
    The National Corrections Reporting Program (NCRP) compiles offender-level data on admissions and releases from state and federal prisons and post-confinement community supervision. The data are used to monitor the nation's correctional population and address specific policy questions related to recidivism, prisoner reentry, and trends in demographic characteristics of the incarcerated and community supervision populations. The Bureau of Justice Statistics (BJS) has administered the NCRP since 1983. The United States Bureau of the Census served as data collection agent for BJS until October 2010, when Abt Associates assumed this position. From 2000 to 2009, NCRP data were archived each year in four, year-specific files that corresponded to the four files that states were asked to submit to the Census Bureau. The four files are: Prison Admissions (Part A), Prison Releases (Part B), Parole Exits (Part C), and Prison Custody (Part D). For example, the 2009 NCRP archive consists of prison admissions occurring in 2009, prison releases occurring in 2009, parole exits occurring in 2009, and prisoners in custody on December 31, 2009. Starting in 2011, NCRP data will be archived in a single, multi-year Term Record file. A Term Record represents a single period of incarceration for an individual offender. Each year, the archived Term Record file will be replaced by a new Term Record file that incorporates new NCRP data collected and processed during the previous year, as well as updates to previously collected data. The Term Records were created from the Prison Admissions (Part A), Prison Releases (Part B), and Prison Custody (Part D) records submitted by states since 2000. With a few lines of computing code (included with the archive), an analyst can create a prison admission, release, or custody file from the Term Record file. In addition to the Term Record file, two additional files are being archived: (1) Prison Admissions (Part A), Prison Releases (Part B), and Prison Custody (Part D) records that were not used in building the Term Record file and (2) Part C (Parole Exit) records collected from January 1, 2011 to October 31, 2012.

    United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
    The National Corrections Reporting Program gathers data on prisoners entering and leaving the custody or supervision of state and federal authorities. The dataset is comprised of four types of data: prisoners who were admitted to prison (Part 1), released from prison (Part 2), released from parole (Part 3), or in prison at year end (Part 4). The National Prison Statistics (NPS) program was established in 1926 by the Bureau of the Census in response to a congressional mandate to compile national information on the populations confined in correctional institutions. This program described the characteristics and counts of prison inmates during each calendar year. Since its initiation, responsibility for this program has shifted among several agencies -- in 1950 it was transferred to the Federal Bureau of Prisons and to the Law Enforcement Assistance Administration in 1971. Since 1972, the Bureau of Census, under agreement with the Department of Justice, has had responsibility for compiling the statistical data. Census staff negotiates directly with each state, assembles and edits the data, and prepares the data for analysis and publication.

This program described the characteristics and counts of prison inmates during each calendar year. Since its initiation, responsibility for this program has shifted among several agencies -- in 1950 it was transferred to the Federal Bureau of Prisons and to the Law Enforcement Assistance Administration in 1971. Since 1972, the Bureau of Census, under agreement with the Department of Justice, has had responsibility for compiling the statistical data. Census staff negotiates directly with each state, assembles and edits the data, and prepares the data for analysis and publication.

    National Prisoner Statistics, [United States], 1978-2019 (ICPSR 37986)
    United States. Bureau of Justice Statistics
    The National Prisoner Statistics (NPS) data collection began in 1926 in response to a congressional mandate to gather information on persons incarcerated in state and federal prisons. Originally under the auspices of the U.S. Census Bureau, the collection moved to the Bureau of Prisons in 1950, and then in 1971 to the National Criminal Justice Information and Statistics Service, the precursor to the Bureau of Justice Statistics (BJS) which was established in 1979. From 1979 to 2013, the Census Bureau was the NPS data collection agent. In 2014, the collection was competitively bid in conjunction with the National Corrections Reporting Program (NCRP), since many of the respondents for NPS and NCRP are the same. The contract was awarded to Abt Associates, Inc. The NPS is administered to 51 respondents. Before 2001, the District of Columbia was also a respondent, but responsibility for housing the District of Columbia's sentenced prisoners was transferred to the Federal Bureau of Prisons, and by yearend 2001 the District of Columbia no longer operated a prison system. The NPS provides an enumeration of persons in state and federal prisons and collects data on key characteristics of the nation's prison population. NPS has been adapted over time to keep pace with the changing information needs of the public, researchers, and federal, state, and local governments.

    Examining Prison Stays in Michigan, 1985-2008 (ICPSR 37034)
    Smith, Justin
    These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. 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 sought to analyze the length of time served by state prisoners in Michigan from 1985 to 2008. It was conducted to address research that showed Michigan had the longest prison stays in the United States of America, the substantial impact that time served had upon state prison populations, and to assess the effect of parole and sentencing policy on time-served. The research utilized National Corrections Reporting Program (NCRP) data available through the National Archive of Criminal Justice Data (NACJD) in order to build upon past-research and contribute to the understanding of state-specific patterns and trends across offenses and racial groups. In order to address policy effects upon time served, the purpose of this study was to contextualize patterns of time served across 20 years within the parole and sentencing policy changes in Michigan; the impact of reforms in 1999 were of particular focus. There are no data files available with this study. Only syntax files used by the researcher(s) are provided.

    Survey of Prison Inmates, United States, 2016 (ICPSR 37692)
    United States. Bureau of Justice Statistics
    To fulfill part of its mission, the Bureau of Justice Statistics (BJS) conducted the Survey of Prison Inmates (SPI), a national, wide-ranging survey of prisoners age 18 or older who were incarcerated in state or federal correctional facilities within the United States. SPI provides national statistics on prisoner characteristics across a variety of domains, such as current offense and sentence, incident characteristics, firearm possession and sources, criminal history, demographic and socioeconomic characteristics, family background, drug and alcohol use and treatment, mental and physical health and treatment, and facility programs and rules violations. SPI can also be used to track changes in these characteristics over time, describe special populations of prisoners, and identify policy-relevant changes in the state and federal prison populations. Formerly the Survey of Inmates in State and Federal Correctional Facilities (SISFCF), this survey was renamed SPI with the 2016 iteration.

    Recidivism Among Young Parolees: a Study of Inmates Released from Prison in 22 States, 1978 (ICPSR 8673)
    United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
    This study examines the criminal activities of a group of young offenders after their release from prison to parole supervision. Previous studies have examined recidivism using arrests as the principal measure, whereas this study examines a variety of factors, including length of incarceration, age, sex, race, prior arrest record, prosecutions, length of time between parole and rearrest, parolees not prosecuted for new offenses but having their parole revoked, rearrests in states other than the paroling states, and the nature and location of rearrest charges. Parolees in the 22 states covered in this study account for 50 percent of all state prisoners paroled in the United States in 1978.

    Effects of Defense Counsel on Homicide Case Outcomes in Philadelphia, Pennsylvania, 1995-2004 [United States] (ICPSR 32541)
    Anderson, James; Heaton, Paul
    This study measured the difference that defense counsel made to the outcome of homicide and death penalty cases. One in five indigent murder defendants in Philadelphia were randomly assigned representation by the Defender Association of Philadelphia while the remainder received court-appointed private attorneys. This study's research design utilized this random assignment to measure how defense counsel affected murder case outcomes. The research team collected data on 3,157 defendants charged with murder in Philadelphia Municipal Court between 1995-2004, using records provided by the Philadelphia Courts (First Judicial District of Pennsylvania). Data were also obtained from the Philadelphia Court of Common Pleas, the Pennsylvania Unified Judicial System web portal, the National Corrections Reporting Program, and the 2000 Census. This study contains a total of 47 variables including public defender representation, defendant demographics, ZIP code characteristics, prior criminal history, case characteristics, case outcomes, and case handling procedures.

    Unintended Impacts of Sentencing Reforms and Incarceration on Family Structure in the United States, 1984-1998 (ICPSR 3662)
    Myers Jr., Samuel L.
    This project sought to investigate a possible relationship between sentencing guidelines and family structure in the United States. The research team developed three research modules that employed a variety of data sources and approaches to understand family destabilization and community distress, which cannot be observed directly. These three research modules were used to discover causal relationships between male withdrawal from productive spheres of the economy and resulting changes in the community and families. The research modules approached the issue of sentencing guidelines and family structure by studying: (1) the flow of inmates into prison (Module A), (2) the role of and issues related to sentencing reform (Module B), and family disruption in a single state (Module C). Module A utilized the Uniform Crime Reporting (UCR) Program data for 1984 and 1993 (Parts 1 and 2), the 1984 and 1993 National Correctional Reporting Program (NCRP) data (Parts 3-6), the Urban Institute's 1980 and 1990 Underclass Database (UDB) (Part 7), the 1985 and 1994 National Longitudinal Survey on Youth (NLSY) (Parts 8 and 9), and county population, social, and economic data from the Current Population Survey, County Business Patterns, and United States Vital Statistics (Parts 10-12). The focus of this module was the relationship between family instability, as measured by female-headed families, and three societal characteristics, namely underclass measures in county of residence, individual characteristics, and flows of inmates. Module B examined the effects of statewide incarceration and sentencing changes on marriage markets and family structure. Module B utilized data from the Current Population Survey for 1985 and 1994 (Part 12) and the United States Statistical Abstracts (Part 13), as well as state-level data (Parts 14 and 15) to measure the Darity-Myers sex ratio and expected welfare income. The relationship between these two factors and family structure, sentencing guidelines, and minimum sentences for drug-related crimes was then measured. Module C used data collected from inmates entering the Minnesota prison system in 1997 and 1998 (Part 16), information from the 1990 Census (Part 17), and the Minnesota Crime Survey (Part 18) to assess any connections between incarceration and family structure. Module C focused on a single state with sentencing guidelines with the goal of understanding how sentencing reforms and the impacts of the local community factors affect inmate family structure. The researchers wanted to know if the aspects of locations that lose marriageable males to prison were more important than individual inmate characteristics with respect to the probability that someone will be imprisoned and leave behind dependent children. Variables in Parts 1 and 2 document arrests by race for arson, assault, auto theft, burglary, drugs, homicide, larceny, manslaughter, rape, robbery, sexual assault, and weapons. Variables in Parts 3 and 4 document prison admissions, while variables in Parts 5 and 6 document prison releases. Variables in Part 7 include the number of households on public assistance, education and income levels of residents by race, labor force participation by race, unemployment by race, percentage of population of different races, poverty rate by race, men in the military by race, and marriage pool by race. Variables in Parts 8 and 9 include age, county, education, employment status, family income, marital status, race, residen,ce type, sex, and state. Part 10 provides county population data. Part 11 contains two different state identifiers. Variables in Part 12 describe mortality data and welfare data. Part 13 contains data from the United States Statistical Abstracts, including welfare and poverty variables. Variables in Parts 14 and 15 include number of children, age, education, family type, gender, head of household, marital status, race, religion, and state. Variables in Part 16 cover admission date, admission type, age, county, education, language, length of sentence, marital status, military status, sentence, sex, state, and ZIP code. Part 17 contains demographic data by Minnesota ZIP code, such as age categories, race, divorces, number of children, home ownership, and unemployment. Part 18 includes Minnesota crime data as well as some demographic variables, such as race, education, and poverty ratio.

    National Prisoner Statistics Program - Coronavirus Pandemic Supplement, [United States], 2020-2021 (ICPSR 38446)
    United States. Bureau of Justice Statistics
    The Bureau of Justice Statistics (BJS) began designing the National Prisoner Statistics Program - Coronavirus Pandemic Supplement (NPS-CPan) in spring 2020, while simultaneously adding questions on the effects of COVID-19 to its Annual Survey of Jails and Annual Surveys of Probation and Parole. The NPS-CPan was conducted from April to October, 2021 by Abt Associates, Inc. on behalf of BJS, as part of the existing multiyear award to collect annual National Prisoner Statistics (NPS-1b) and National Corrections Reporting Program (NCRP) data. The NPS-CPan was designed to be fielded a single time, and was administered to the 50 state departments of corrections (DOCs) and the federal Bureau of Prisons (BOP), which is also responsible for housing felons sentenced in the District of Columbia. Respondents were asked to complete a survey requesting details on the monthly custody prison population, admissions, and releases of prisoners from January 2020 to February 2021 and counts and demographic distributions of prisoners who tested positive for and who died from COVID-19. In addition, questions covered policies and practices used by states and the BOP to mitigate transmission of the virus, expedite release of prisoners, and determine the process by which staff and prisoners were vaccinated in early 2021. This 14-month survey period allowed BJS to track monthly trends in admissions and custody populations immediately prior to widespread COVID-19 infections in the United States, as well as capture the introduction of vaccines to prison systems.
