title: Census of State and Federal Adult Correctional Facilities, 1990
title: Version 2

description: This census is the fourth enumeration of state adult correctional institutions and the first of federal institutions sponsored by the Bureau of Justice Statistics and conducted by the Bureau of the Census. Earlier censuses were completed in 1974 (ICPSR 7811), 1979 (ICPSR 7852), and 1984 (ICPSR 8444). Separate questionnaires were devised for confinement facilities and for community-based facilities. Variables describing the facilities include physical security, age, functions, capacity, confinement space, available medical facilities, programs, inmate/resident work assignments, staff employment, facilities under court order/consent decree for conditions of confinement, capital and operating expenditures, custody level of inmates/residents, one-day count and average daily population, race/ethnicity of inmates/residents, inmate/resident deaths, special inmate/resident counts, and assaults and incidents by inmates. An addendum on drug control activities in state and federal facilities was included for the first time in the 1990 census. Facilities were asked to provide information on the following: procedures used with inmates/residents, visitors, and staff to keep out illegal drugs and drug paraphernalia, inmate/resident drug-testing practices, including the criteria for testing inmates/residents, the number of inmates/residents tested in total and by specific drug, and the number that tested positive, staff drug testing, including groups and basis for testing, number tested, and procedures when tests were positive, and capacity and enrollment in various types of drug treatment and intervention programs.
description: Data were collected from 957 state prison facilities, 250 state community-based facilities, and 80 federal prisons operating on June 29, 1990.

description: The facility universe was developed from the Census of State Adult Correctional Facilities conducted in 1984. This list was revised using the 1990 American Correctional Association Directory and information obtained from state correctional administrators and the Federal Bureau of Prisons. The census included prisons, prison farms, reception, diagnostic, and classification centers, road camps, forestry and conservation camps, youthful offender facilities (except in California), vocational training facilities, correctional drug and alcohol treatment facilities, and state-operated local detention facilities in Alaska, Connecticut, Delaware, Hawaii, Rhode Island, and Vermont.
description: When all prisons in the census did not provide data on particular variables, estimated figures were used where indicated. Total figures were estimated by multiplying the known or reported numbers by the ratio of the total relevant population to the reported population. All figures were estimated independently and total estimates were therefore larger than the sum of all subgroup estimates. The total population figure used in the projections varied, depending upon which figure was most appropriate. The two available population figures are the average daily population and the prison count on the reference day for the census--June 29, 1990. For drug testing, the basis for estimation was the average daily population, and for drug treatment capacity and enrollment, the basis was the one-day count.
