National jail census, 1970

This census provides information on county and municipal jails facilities and their administration. For all jails, the data include number of prisoners and their reason for being held, age and sex of prisoners, maximum sentence which could be served in the facility, facility capacity and age, types of security available, and operating expenditures. For jails in counties and municipalities with a population of 25,000 or more, there are data on quarterly jail population, age of cells, and availability of service facilities and programs for inmates.
