NOTE: SD = standard deviation.

a The incarceration rate is obtained from the ratio of the number of resident inmates in a daily census of prison populations each year to the total population of each state. Inmate data were obtained from annual published reports of the corrections department in each state. Annual population estimates for each state were obtained from Bureau of Census (1969, 1970, 1980, 1988, and 1989).

b The expected time served per arrest (QiS) reflects the number of person-years served in prison per 100 adult arrests in a year. It is obtained from the ratio of the number of resident inmates from a daily census of prison populations to the number of arrests of adults. Inmate data were obtained from annual published reports of the corrections department in each state. Arrest data by state were obtained from unpublished supplementary tables from the FBI Uniform Crime Reports program.
