Survey methodology, definitions of terms, and jurisdictional explanatory notes
Note: The following information has been excerpted from U.S. Department of Justice, Bureau of Justice Statistics, Correctional Populations in the United States, 1995, NCJ-163916 (Washington, DC: U.S. Department of Justice, 1997); Prisoners in 1997, Bulletin NCJ-170014 (Washington, DC: U.S. Department of Justice, August 1998), pp. 13-15; and Probation and Parole Populations 1997, Press Release NCJ-172216 (Washington, DC: U.S. Department of Justice, August 1998), p. 6. Non-substantive editorial adaptations have been made.
Survey methodology for prisoner data
The Bureau of Justice Statistics (BJS), with the U.S. Bureau of the Census as its collection agent, obtains yearend and midyear counts of prisoners from departments of correction in each of the 50 States, the District of Columbia, and the Federal Bureau of Prisons through the National Prisoner Statistics (NPS) program. In an effort to collect comparable data from all jurisdictions, NPS distinguishes prisoners in custody from those under jurisdiction. To have custody of a prisoner, a State must hold that person in one of its facilities. To have jurisdiction means that a State has legal authority over the prisoner. Prisoners under a State's jurisdiction may be in the custody of a local jail, another State's prison, or other correctional facility. Some States are unable to provide both custody and jurisdiction counts. Excluded from NPS counts are persons confined in locally administered confinement facilities who are under the jurisdiction of local authorities. NPS counts include all inmates in State-operated facilities in Alaska, Connecticut, Delaware, Hawaii, Rhode Island, and Vermont, which have combined jail-prison systems.
In each jurisdiction, the questionnaire was completed by a central agency reporting for institutions within the correctional system. This procedure was also used by the Federal Bureau of Prisons in supplying data on Federal institutions. Because the information was derived from a complete enumeration rather than a survey, the statistical data are not affected by sampling error. Response errors were held to a minimum by means of a systematic telephone followup and, where necessary, other control procedures. Thus, the yearend counts are generally considered reliable. Because of the absence of standardized administrative and record keeping practices from State to State, the data for admissions and releases are not always entirely comparable across jurisdictions.
Many States revise the yearend number reported for the previous year. Those revisions are made in the total, not the detail. For example, the number of blacks, whites, and members of other races for 1995 were not changed by a State in 1996 to equal its revised 1995 total.
* National Prisoner Statistics category definitions
Jurisdiction population, Dec. 31-- Includes all inmates under jurisdiction of State correctional authorities on Dec. 31 regardless of location. Does not include other jurisdictions' inmates (for example, inmates from other States, pretrial detainees) merely housed in prisons.
Custody population, Dec. 31-- Includes all inmates in the State's custody, that is, housed in State correctional facilities on Dec. 31. Does not include State inmates housed outside State prison facilities; does include other jurisdictions' inmates (for example, inmates from other States, the courts, local jails) housed in the State's facilities.
Overcrowding, Dec. 31--Includes all State prison inmates housed in local jails on Dec. 31 and as a direct result of State prison overcrowding. Does not include State prison inmates held in local jails for other reasons (for example, work release, court appearance, etc.).
New court commitments--Includes all inmates who were admitted with new sentences, that is, these inmates were not readmitted for any sentences for which they had already served some prison time. This category includes probation violators entering prison for the first time on the probated offenses. Does not include parole violators with new sentences.
Parole violators with new sentences--Includes all parolees returned with new sentences.
Other conditional release violators with new sentences--Includes all individuals on conditional release (other than parole) who are returned with new sentences, for example, returns from supervised mandatory release, from shock probation, etc.
Parole violators only, no new sentences--Includes all parolees returned only for formal revocations of parole that were not accompanied by new sentences. If the parole was not formally revoked, that is, the parolee was held only temporarily pending a hearing, no admission occurred for NPS purposes.
Other conditional release violators only, no new sentences--Same as above, substituting conditional release violator for parole violator.
Transfers from other jurisdictions--Includes all inmates transferred to a State's jurisdiction to continue sentences already in force. Does not include admissions if State does not acquire jurisdiction. Does not include movements from prison to prison within State.

Escapee returns, with or without new sentences--Includes all returns from escape, that is, unlawful departures from a State correctional facility or from the custody of State correctional personnel.
Returns from appeal/bond--Includes all inmates reinstated to correctional jurisdiction from long-term jurisdictional absences on appeal or bond. Does not include returns from short-term movements (less than 30 days) to court (that is, where the State retains jurisdiction).
Other admissions--Includes all other admissions not covered by the above categories.
Unconditional--An unconditional release occurs only if the released inmate cannot be imprisoned for any sentence for which he/she was in prison.

Classification by race often depends on the reporting program and the State. A few States reported two categories: white and nonwhite. A few others categorized Hispanic offenders as belonging to "Other race." The number of persons with certain racial backgrounds were sometimes estimated.
White--A person having origins in any of the original peoples of Europe, North Africa, or the Middle East.
Black--A person having origins in any of the black racial groups of Africa.
American Indian or Alaska Native--A person having origins in any of the original peoples of North America, who maintains cultural identification through tribal affiliation or community recognition.
Asian or Pacific Islander--A person having origins in any of the original peoples of the Far East, Southeast Asia, the Indian Subcontinent, or the Pacific Islands. This area includes, for example, China, India, Japan, Korea, the Philippine Islands, and Samoa.
Other--Any other race not covered by the above categories.
Not known--Any inmate whose racial origin is unknown.
A person of Hispanic origin may be of any race; however, a few States treat the ethnic category as a racial one. Reporting officials usually rely on self-definition, but some States classify according to surname.
Hispanic--A person of Mexican, Puerto Rican, Cuban, Central or South American, or other Spanish culture or origin, regardless of race.
Not Hispanic--A person not covered by the above category.
Not known--Any inmate whose ethnic origin is unknown. *
