Mayor de Blasio on Monday ripped The Post’s coverage of the homelessness crisis — and touted an estimated drop in the vagrant population based on a single-day census conducted in sub-freezing temperatures.

“With all due respect to your publication, which is well known for fear-mongering, let’s look at the facts. We have had a reduction in crime, we’ve had a reduction in street homelessness, and we are going to deal with problems related to mental health much more aggressively,” he said.

Hizzoner’s claim is based on a figure taken from a Department of Homeless Services’ survey conducted on Feb. 9 — with temperatures as low as 25 degrees. This year’s tally was 3,182, down from 3,357 in 2014.
