DESCRIPTION: National Prisoner Statistics (NPS)

Status: Active
Frequency: Bi-annually
Latest data available: 2009

Dataset(s): This dataset is not archived at this time.

NPS has been collected by the government since 1923. The collection definitions and data items have changed occasionally over the years, as has the ability of jurisdictions to report data.

NPS produces midyear and yearend national and state-level data on the numbers of prisoners in state and federal prison facilities. Data elements include gender, race, prisoners held in private facilities and local jails, admissions and releases by type, system capacity, persons under age 18, non-citizens, and HIV status. Findings are released in the Prisoners and Prison Inmates at Midyear series.

Instruments available:

methodology

Data are collected on June 30 and December 31 from the fifty state departments of correction and the federal bureau of prisons (BOP). Data from the District of Columbiawas collected until 2001, when the district ceased operating a prison system; since 2001 dc inmates sentenced to more than 1 year are the responsibility of the bop system. Respondents are permitted to update the previous years' data when submitting the current year. Data is submitted via mail, fax, or online at a secure site.

Changes over time

The following categories were added or altered over time - admission and release categories; race and ethnicity categories (1999, 2005), inmates held in local jails due to crowding; inmates held in private facilities, local jails, or in another state (1999); person under 18 held (1998); noncitizens held (1998); HIV information (1999).

General Information: Capital Punishment, NPS-8 collection

HOMEPAGE:

DESCRIPTION: Capital Punishment, National Prisoner Statistics

Status: Active
Frequency: Annually
Latest data available: 2009

Dataset(s): Available at the Inter-University Consortium for Political & Social Science Research (ICPSR), University of Michigan:

The corrections unit collects data on persons held under sentence of death and persons executed during the calendar year from the state departments of correction and the Federal Bureau of Prisons (BOP). Data collection on executions began in 1930; sentencing information was added in 1973.

Preliminary counts of executions carried out during the subsequent calendar year are also presented. Series provides an annual summary of the movement of prisoners received and removed from under sentence of death. Data on offenders' sex, race, Hispanic origin, education, marital status, age at time of arrest for the capital offense, legal status at time of the offense, and method of removal are presented. The page also includes information on executions, trends, and time between imposition of death sentence and execution.

Instruments available:

methodology

Data on persons under sentence of death on December 31 are obtained from the department of corrections in each jurisdiction authorizing the death penalty during the report year. Information on the status of death penalty statutes is obtained from the Office of the Attorney General in each of the 50 states, the District of Columbia, and the Federal Government.
NPS-8 covers all persons under sentence of death at any time during the year who were held in a state or federal nonmilitary correctional facility. Included are capital offenders transferred from prison to mental hospitals and those who may have escaped from custody. Excluded are persons whose death sentences have been overturned by the court, regardless of their current incarceration status.

The statistics reported in this Bulletin may differ from data collected by other organizations for a variety of reasons: (1) NPS-8 adds inmates to the population under sentence of death not at sentencing but at the time they are admitted to a state or federal correctional facility; (2) If inmates entered prison under a death sentence or were reported as being relieved of a death sentence in one year but the court had acted in the previous year, the counts are adjusted to reflect the dates of court decisions (see the note on table 4 for the affected jurisdictions); and (3) NPS-8 counts are always for the last day of the calendar year and will differ from counts for more recent periods. All data in this report have been reviewed for accuracy by the data providers in each jurisdiction prior to publication.

The National Inmate Survey (NIS) is part of the BJS National Prison Rape Statistics Program that gathers mandated data on the incidence of prevalence of sexual assault in correctional facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108- 79). The Act requires a 10% sample of correctional facilities to be listed by incidence of sexual assault, with a minimum of one prison and one jail facility in each state. Data are collected directly from inmates in a private setting using audio computer-assisted self interview (ACASI) technology with a touch-screen laptop and an audio feed to maximize inmate confidentiality and minimize literacy issues. See Methodology in reports for sampling and weighting information.

General Information: National Survey of Youth in Custody

Homepage:

DESCRIPTION: National Survey of Youth in Custody (NSYC)

Status: Active
Frequency: 2008-09 (2012-13 collection planned)
Latest data available: 2008-09
Dataset(s): This dataset is not archived at this time. See information below.

The National Survey of Youth in Custody (NSYC)is part of the BJS National Prison Rape Statistics Program to gather mandated data on the incidence of prevalence of sexual assault in juvenile facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108-79). The Act requires a 10% sample of juvenile facilities to be listed by incidence of sexual assault. Data are collected directly from youth in a private setting using audio computer-assisted self interview (ACASI) technology with a touch-screen laptop and an audio feed to maximize inmate confidentiality and minimize literacy issues. The first year of collection includes nearly 200 juvenile facilities, with an estimated 10,000 completed interviews with youth. The first report from the 2008-09 NSYC survey was released in January 2010.

Instruments available:

METHODOLOGY

The 2008-09 NSYC survey consisted of an audio computer-assisted self-interview (ACASI) in which youth, using a touch-screen, interacted with a computerized questionnaire and followed audio instructions delivered via headphones. The NSYC utilized self-administered procedures to ensure the confidentiality of the reporting youths and to encourage fuller reporting of victimization. The survey made use of audio technology to provide assistance to youth with varying levels of literacy and language skills. Approximately 98% of the interviews were conducted in English; 2% in Spanish.

Administrators in each state, county, and private facility determined the type of consent required for youths to be eligible for participation. Administrators provided in loco parentis (ILP) consent in 63 facilities. In loco parentis is when administrators provide consent “in the place of the parent” to contact youth. In the remaining 132 facilities, administrators required consent from the youths’ parents or guardians (PGC). Youth in all facilities also had to assent to participate in the interview.

In each sampled PGC facility, administrators were asked 8 weeks prior to data collection to provide a roster of all adjudicated youth assigned a bed; in ILP facilities a roster was provided 4 weeks prior to data collection.

All youth were sampled in ILP facilities and in PGC facilities with 240 or fewer youth on the roster. In larger PGC facilities, all females and a random sample of males were selected. In both PGC and ILP facilities all incoming youth were added to the sample up to 4 weeks prior to the survey. Youth who had been present in the facility at least 4 weeks prior to the survey and were present at the time of the survey were considered eligible.

The result of this process yielded a sample representing 26,551 adjudicated youth held nationwide in state operated and large locally or privately operated juvenile facilities. A total of 10,263 youth participated in the survey. Of these, 1,065 received an alternative survey on drug and alcohol use and treatment, and 9,198 youth participated in the survey of sexual victimization.

CHANGES OVER TIME

Based on feedback from juvenile administrators and experts in investigating allegations of child abuse and neglect, BJS has added new items to measure the accuracy of youth self-reports, included new items to more fully understand staff sexual misconduct, developed methods to enhance response rates, and expanded the sample to include youth held in smaller facilities and facilities under contract to state juvenile correctional authorities. A new component of nsyc-2 is the collection of information about each facility and living unit. NSYC-2 will collect data on facility staffing, use of video surveillance, characteristics of youth held, and factors related to placement of youth in different living units within the facility.

The National Corrections Reporting Program (NCRP) collects administrative data annually on prison admissions and releases and on parole entries and discharges in participating jurisdictions. Demographic information, conviction offenses, sentence length, minimum time to be served, credited jail time, type of admission, type of release, and time served are collected from individual prisoner records. The collection began in 1983 and is conducted annually. Beginning in 1999, some jurisdictions also began providing a stock file for all inmates held at yearend. About 41 states provide various types of data for this collection.

METHODOLOGY:

Administrative data are gathered annually from the Departments of Corrections and Parole in about 41 states on prisoners entering and leaving custody or supervision. Data are provided for prisoners who were admitted to prison (Part A), released from prison (Part B), or released from parole (Part C).Variables include incarceration history, current offenses, and total time served. Background information on individuals includes year of birth, sex, age, race, Hispanic origin, and educational attainment.
