Black and white shooting rates in New York

Heather MacDonald cites some interesting statistics in her piece today in the NY Daily News. Based on victim and witness reports, 82% of all shootings in New York are by blacks even though they are only 24% of the city's residents. Whites are 35% of the city but commit only 1% of the shootings.

Let's get a comparison of the two races. If we divide 82 by 24 (the black numbers), we get 3.42. If we divide 1 by 35 (the white numbers), we get 0.03. When you divide 3.42 by 0.03, the result is 114. So the black shooting rate in New York is 114 times that of whites. 

I know there are large income differences between blacks and whites there, but holy crap.
