Ten Times As Many People Are Bitten By New Yorkers Than Sharks?

The Shark Foundation claims that,

Alone in New York people are bitten 10 times more each year by other people than worldwide by sharks.

But they don’t provide any citation for this claim, and a number of other sites that repeat this seem to ultimately lead back to The Shark Foundation’s claim. So far I have been unable to locate statistics on the total number of people bitten by others in New York City.

Given the size of New York City and the small number of people bitten by sharks each year, on the surface this seems plausible, but I’d like to find some actual evidence for this claim.
