The Homeless Outreach Population Estimate (HOPE) is an annual estimate to assess the number of individuals living in New York City's public spaces. On the night of HOPE, thousands of volunteers are assembled and sent out in teams to survey New York's streets, subways and parks. Conducted by the NYC Department of Homeless Services (DHS), HOPE is a point-in-time estimate of unsheltered individuals to project service needs, allocate resources for the street homeless population, and educate and engage New Yorkers.

HOPE serves to increase public accountability and continually evaluate and improve the programming designed to help street homeless New Yorkers. The event began in Manhattan in 2003 and has expanded Citywide every year since 2005. The City employs a rigorous methodology endorsed as the gold standard by the U.S. Department of Housing and Urban Development (HUD). Cities wishing to draw down funding from the McKinney-Vento Act aimed at homelessness are required to conduct biennial point-in-time surveys of their unsheltered populations, but New York City began its survey before this requirement even existed.

HOPE is an integral part of New York City's approach to addressing homelessness.
