New York City paid and average of $167,731 to feed, house and guard each of its 12,300 jail inmates last year, reports the New York Times, citing a study by the Independent Budget Office. 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.
