sample of jail jurisdictions was selected for the 2003 survey. The
sample included public and private jails in 878 selected jail
jurisdictions including 55 regional jails. A stratified random sample
of county or city jurisdictions stratified by average daily population
(ADP) as reported by the 1999 Census of Jails. Large jails and
regional jails were in the sample with certainty.
