Presents the number of jails and jail inmates at midyear 2012. This report describes annual change in jail populations and patterns of change from 2000 through 2012. It shows rated capacity of jails and percent of capacity occupied. The report also provides estimates of admissions to jails, details the volume of movement among the jail population, and presents the distribution of jail inmates by sex, race, and Hispanic origin. It includes information about the effect of California's public safety realignment on jail populations. The report also includes standard errors for jail estimates.


  • After three consecutive years of decline in the jail inmate population, the number of persons confined in county and city jails (744,524) increased by 1.2% (or 8,923 inmates) between midyear 2011 and midyear 2012.
  • Rated capacity in jails reached 886,947 beds at midyear 2012, an increase of 0.8% (7,225 beds) from 879,722 beds in midyear 2011.
  • Local jails admitted an estimated 11.6 million persons during the 12-month period ending June 30, 2012, which was similar to 2011 (11.8 million) and down from 13.6 million in 2008.
