Mayor Bloomberg was recently touting how wonderfully safe the Big Apple is with all it's restrictive gun laws. However, things ain't exactly paradise. Methinks I've spotted a bit of trouble that most of us probably already suspected.
NYC is divided into 5 Boroughs: Bronx, Brooklyn, Manhattan, Queens and Staten Island, but the NYPD is divided up into 8 Patrol Boroughs with Brooklyn, Manhattan and Queens each split into a North and South Patrol Borough.
The raw crime stats are available on the NYPD website by Patrol Borough and even Precinct. We all know that crime rates, not raw stats, are a more accurate indicator of crime, and the trick was how to come up with the rates. It took a bit of searching, but I was able to cobble the rates together.
I started with the NYC Department of City Planning Census numbers. They would seem to have more accurate data as U.S. Department of Census now uses the DCP numbers--at least according to the DCP website.
DCP has population stats and maps by Community District. I matched the DCP Community District maps to the NYPD Patrol Borough maps, and it looks like the Patrol Boroughs break cleanly along Community Districts. This gave me the breakdown of which Community Districts were in the North Patrol Borough and which were in the South Patrol Borough of a given Borough.
I pulled in the 2005 DCP Borough population estimates, and extrapolated Patrol Borough population growth from Borough population growth. From there, it's simple arithmetic to come up with Patrol Borough crime rates.
As one can clearly see, there are very sharp divides with a lot of peaks and valleys in NYC crime.
Yeah, yeah, yeah. I know. Argue against not should gun control to crime rates be used.
