English: Timeline of yearly U.S criminal justice spending. 1982-2007. By function (police, corrections, judicial). Inflation-adjusted expenditures in 2007 constant dollars. $228 billion total in 2007. $50 billion for judicial and legal costs. $104 billion for police. $74 billion for corrections alone. There were 2,296,400 adult inmates in 2007, and 86,814 juveniles in detention. That adds up to 2,383,214 inmates. Per inmate costs can not be calculated from this alone because corrections costs also covers probation and parole.
