I used the crime statistics in 1990 New York City for 1987 Metropolis in my story. But I would note that the city has managed to cut its crime rate significantly since then. See: http://www.nyc.gov/html/nypd/downloads/pdf/crime_statistics/cscity.pdf

(And thanks to all of you who helped me find and interpret these stats)
