Nearly 300 volunteers had until 2 a.m. to find and and survey every homeless person they can find on the streets of Washington, D.C., one of 18 assigned areas nationwide. It’s part of Department of Housing and Urban Development’s annual point-in-time count of the homeless. Last year, HUD counted a nationwide total of 578,424 homeless, 7,748 of whom lived in the District.
