Annual Survey of Jails

The Annual Survey of Jails (ASJ) is a nationally representative survey of county or city jail jurisdictions and regional jails in the country. Started in 1982, the ASJ tracks changes in the number and characteristics of local jail inmates nationwide. It also collects annual data on jail inmate turnover, jail capacity, and space usage by other authorities. Around 900 agencies representing approximately 3,000 jails nationwide participate in the ASJ each year.
