The NYC Crime Map is an interactive map produced by the City which lets you play with crime data per precinct.
Crime data is provided in map format for the, “seven major NYS Penal Law felonies” (Murder and Non-Negligent Manslaughter, Rape, Robbery, Felonious Assault, Burglary, Grand Larceny and Grand Larceny Motor Vehicle. Attempted crimes are recorded as that crime with the exception of Attempted Murder which is recorded as a Felonious Assault.) A crime map can be presented cumulatively year to date, previous year cumulative and by any specific month in either period. The opening and default map views are of the most recent full month count of all seven major crimes.
The map is updated frequently, but runs about 2 months behind the current date as police reports are collected, filed and digitized pretty slowly. How safe is your neighborhood?
