Report Key Factors in California’s Jail Construction Needs By Magnus Lofstrom, Brandon Martin May 7, 2014 Now that California has shifted responsibility for many criminal offenders to the counties, county jail systems face greater capacity challenges. This report highlights two important factors in addressing jail capacity constraints: aging jail facilities and long-term needs. We show that a number of facilities are old and likely in need of costly updates or replacement and that growth in the state’s population is likely to exert significant pressure on the county jail system. Our analysis suggests that a thoughtful combination of further jail construction and decreased reliance on incarceration is needed, given the magnitude of the current and future jail needs.
