(DNAINFO)  Amy Zimmer — More than 57,000 adults and children slept in city shelters Thursday night, according to the most recent figures from the city’s Department of Homeless Services.

Thousands more slept on the streets, in the subway system and in other public spaces.

With an affordable housing crisis, the city’s shelter population is at the highest levels since the Great Depression, according to the Coalition for the Homeless advocacy group.

New Yorkers seem increasingly concerned and frustrated: The number of 311 calls about the homeless jumped nearly 60 percent since Mayor Bill de Blasio took office, DNAinfo previously reported.

That frustration has manifested in the real estate world.
