The number of local jail inmates more than tripled from approximately 207,000 in 1982 to over 691,000 in 2003. Adults on probation increased from over 1.4 million to about 4.1 million persons. Overall, corrections employment more than doubled from nearly 300,000 to over 748,000 during this same period."
