Suspects arrested on criminal charges who cannot make bail or are denied bail are detained in city jails while their cases are being decided. If the arrestee is convicted and sentenced to time in state prison, the period of time already spent in city jails is deducted from their sentence. Time spent in city jails comes at the city’s expense, time in state prison at the state’s expense. Therefore, the longer it takes to convict, the more it costs the city in detention spending that would otherwise be paid by the state.

The average time in city jails credited to inmates newly sentenced to state prisons from Bronx courtrooms grew to 15.7 months in 2012, about six months more than the average in the remainder of the city. If the average in the Bronx had been the same as that in the rest of the city, New York City would have saved about $14 million last year on jail expenditures.
