The detention center's opening comes as the number of youths charged as adults and held at such facilities has been dropping. While the new facility can house up to 60 youths — 50 males and 10 females — the city typically houses fewer than 15 on an average day, according to corrections department spokesman Gerry Shields. In fact, the average daily population has dropped from 44 in fiscal year 2013 to nine this past fiscal year, according to Moyer's agency.
