Congrats to New York’s men and women in blue, and to the NYPD brass as well: Together, you delivered the city’s safest February on modern record.

The overall major-crime index fell 9.7 percent over February 2016, to 6,630. That includes drops in six of seven categories — in all seven if you discount five murders “booked” that month but committed in the past.

Year over year, February rapes fell from 108 to 85; robberies, 1,113 to 954; felonious assaults, 1,400 to 1,287; shootings, 62 to 40. Even counting the old cases, murders rose only from 18 to 20. Burglaries and grand larcenies dropped, too.

It was the lowest crime month since the birth of CompStat — and surely the lowest for decades before that. No wonder the Quinnipiac poll finds that city voters approve of the job cops do in their community 75 percent to 21 percent.

Under Commissioner James O’Neill, New York’s Finest continue to build on a quarter-century of innovation dating to Bill Bratton’s first stint as commissioner under Mayor Rudy Giuliani in 1994.

Back then, expert criminologists insisted nothing could be done — that cities were helpless to control crime. (Strangely, many of those “experts” continue to pontificate without a hint of shame.)

New Yorkers now know better. They’ve seen cumulative progress unparalleled in modern policing. The NYPD has continued to bring crime down far beyond what any other city has seen, and continues to do so even as towns like Baltimore and Chicago are tragically losing ground.

And yes, Mayor de Blasio deserves credit for supporting continued progress and for saying “no” to his progressive allies’ most disastrous anti-cop demands. He knows that New Yorkers won’t buy any excuses: They’ve seen what first-rate policing can do.
