Murders are way up so far this year in Manhattan, The Post has learned.

Sixteen people were killed around the borough between the first of the year and Sunday. Over the same period last year, the figure was 11. That’s an increase of about 45 percent.

Shootings in the borough have also soared.

There have been 50 “shooting incidents’’ since Jan. 1, compared with 31 in the same time period in 2014 — an increase of about 38 percent. Some of these “incidents’’ involved more than one victim.

The number of shooting victims nearly doubled, from 33 to 61.

“City Hall better wake up soon,” a police source said. “When murders and shootings go up in Manhattan, everyone is affected,’’ he said, pointing out that crime impacts business, tourism and the city’s economy as a whole.

He said there are a variety of reasons, from the plummeting number of “stop-and-frisks’’ to the fact that the city needs more officers. “The cops’ hands are tied,’’ he said.
