Annual Survey of Jails: Jurisdiction-Level Data, 2000

This collection provides annual data on jail populations
across the nation and examines the "spillover" on local jails
resulting from the dramatic growth in federal and state prison
populations. These data are used to track growth in the number of
jails and their capacities nationally, changes in the demographics of
the jail population (including sex, race, and adult or juvenile
status), supervision status of persons held, prevalence of crowding
issues, and a count of non-United States citizens within the jail
population.
