Between Jan. 1, 2015, and Aug. 9, 2015, the city's 311 system received 20,242 calls about a homeless person in need of assistance, in an emergency situation or living in an encampment, according to the mayor's office. If the rate of calls continues, the number could surpass 33,500 by the end of the year.
During the same period in 2013 — Mayor Michael Bloomberg's final year in office — 12,715 calls about the homeless were made. For all of 2013, there were 21,882 calls about homeless to 311"http://www.dnainfo.com/new-york/20150813/union-square/311-complaints-about-homeless-have-nearly-doubled-under-mayor-de-blasio
What's your opinion as to why?
A) The tabloid press has made it a front page issue, so it's no surprise that public perception would change, and a perception bias would lead to increased 311 calls.
It's Bloomberg's fault anyway, with his chronic ignoring of the issue, and De Blasio inherited failing institutions which made the problem spiral downwards further.
C) De Blasio's one-term mayorship is to blame: his incompetence has lead to a poor relationship with the police, and along with the City Council a diminishing of enforcement of (especially) quality of life complaints.
D) All of the Above.
One thing is for sure - it's not helping De Blasio's popularity according to the polls.
