But even as New York officials were responding to the bloodshed over the weekend, the city continued to grapple with its own gun violence problem.

Yes, crime in New York is at a two-decade low.

Still, a mass shooting on July 27 at a block party in the Brownsville section of Brooklyn that left one person dead and 11 injured underscored the unsettling increase in violence in recent months, especially in parts of that borough.

How many shootings are there in New York City?

As of July 28, 521 people had been shot this year in New York City, in 441 shooting incidents, according to the police. That’s up from 501 people shot in 413 incidents in the same period a year ago.

The shootings are not spread evenly across the city. Some precincts in Queens and Manhattan have not reported any shootings this year. Others have logged quite a few.
