Murders, assaults, robberies, shootings and hate crimes all rose last year, Mayor de Blasio and NYPD Commissioner Dermot Shea revealed Monday — even as they touted “record low” crime in the city for 2019.

The Big Apple recorded 318 homicides last year — 23 more than 2018, the city officials announced at the NYPD’s monthly crime briefing.

The murder number is the city’s highest since 2016, when 335 homicides were tallied, data show.

“While crime is at a record low in New York City, there is more work to do to ensure that every New Yorker feels safe in their neighborhood,” de Blasio said during a press conference at the Police Academy in Queens. “The uptick in murders is something we take very seriously.”

The NYPD had more than double the number of reclassified murders in 2019, adding 27 murders to the count which occurred in the years prior but the victim died last year or an arrest was made.

Another area of concern addressed at Monday’s meeting was the alarming uptick in hate crimes across the five boroughs, which shot up 20 percent in 2019 — driven by a 26 percent spike in anti-Semitic incidents alone.

There were 234 anti-Semitic crimes reported for the year compared to 186 in 2018, officials said.

“I think that the more light you shine on this, the better,” Shea said. “To get people talking about it internally and externally as much as possible, I think it’s good for it.”

The city has been rocked in the past month by a spate of anti-Semitic attacks, including one in Brooklyn on Dec. 27 that was allegedly committed by Tiffany Harris, who was then released without bail thanks to the state’s new criminal-justice reforms.

The NYPD, in its crime-stats press release, noted the “challenge” posed by the reforms.

“NYPD officers’ work continues amid the challenge of new criminal justice reforms whose effects are already taking hold in New York City,” the release said.

Meanwhile, robberies and assaults — two of the seven major index crimes the NYPD uses to track trends — increased by 3.1 percent and 1.4 percent, respectively, records show.

Shooting incidents rose to 766 in 2019, up 2.9 percent from 2018.

Total index crimes dropped 0.9 percent to 95,521 — the lowest level in the modern era, the NYPD said.

That’s thanks in large part to a decrease in burglaries, from 11,777 to 10,751 recorded.

Grand larcenies declined 1.2 percent, to 43,227 in 2019, and rapes were down 2.5 percent, to 1,760 — although the NYPD acknowledged that rapes continue to be underreported.
