Conducted by the Bureau of the Census, this survey provides
nationally representative data on state prison inmates and sentenced
federal inmates held in federally owned and operated facilities.
Through personal interviews from June-October 1997, inmates in both
state and federal prisons provided information about their current
offense and sentence, criminal history, family background and personal
characteristics, prior drug and alcohol use and treatment programs,
gun possession and use, gang membership, and prison activities,
programs, and services. Prior surveys of state prison inmates, called
SURVEY OF INMATES OF STATE CORRECTIONAL FACILITIES, were conducted in
1974, 1979, 1986, and 1991 (see ICPSR 7811, 7856, 8711, and 6086).
Sentenced federal prison inmates were first interviewed in 1991 (see
SURVEY OF INMATES OF FEDERAL CORRECTIONAL FACILITIES, 1991 [ICPSR
6037]). The federal data are combined with the state data in this
collection. Part 1, Numeric Data, consists of numerically-coded
responses, while Part 2, Alphanumeric Data, contains free-field
responses to "Specify, Other" questions in ASCII text form.
