According to CDCR figures, as of April 2010, 8.261 prisoners are in out-of-state facilities, with 4,076 in Arizona, 2,579 in Mississippi, and 1,606 in Oklahoma.
A 2009 state audit reported that California compensates these out-of-state facilities approximately $30,000 per year to house each prisoner. Although California currently doles out about $248 million annually on this program, the audit determined that the cost of housing prisoners out-of-state is $3,200 less per prisoner than the amount spent to house a prisoner in a comparable CDCR institution.
