New York City is an expensive place to live for just about everyone, including prisoners. The city paid $167,731 to feed, house and guard each inmate last year, according to a study the Independent Budget Office released this week. It is troubling in both human terms and financial terms," Doug Turetsky, the chief of staff for the budget office, said on Friday. With 12,287 inmates shuffling through city jails last year, he said, "it is a significant cost to the city." by nearly any measure, New York City spends more than every other state or city. The Vera Institute of Justice released a study in 2012 that found the aggregate cost of prisons in 2010 in the 40 states that participated was $39 billion. The annual average taxpayer cost in these states was $31,286 per inmate. New York State was the most expensive, with an average cost of $60,000 per prison inmate. The cost of incarcerating people in New York City's jails is nearly three times as much. 83 percent of the expense per prisoner came from wages, benefits for staff and pension costs. Some 76 percent of the inmates in the city were waiting for their cases to be disposed. The wait times have grown even as the number of felonies committed in the city has declined. Since 2002, the time spent waiting for cases to be disposed of has gone to 95 days, from 76 days, [former city correction and probation commissioner Michael] Jacobson said.
