Annual Homeless Assessment Report to Congress

Perhaps the most accurate and current data on homelessness in the United States is reported annually by the Department of Housing and Urban Development (HUD) in the Annual Homeless Assessment Report to Congress (AHAR). The AHAR report relies on data from two sources: single-night, point-in-time counts of both sheltered and unsheltered homeless populations reported on the Continuum of Care applications to HUD; and counts of the sheltered homeless population over a full year provided by a sample of communities based on data in their local Homeless Management Information Systems (HMIS).
