The Annual Homeless Assessment Report (AHAR) is a HUD report to the U.S. Congress that provides nationwide estimates of homelessness, including information about the demographic characteristics of homeless persons, service use patterns, and the capacity to house homeless persons. The report is based primarily on Homeless Management Information Systems (HMIS) data about persons who experience homelessness during a 12-month period. (Source: HUD Exchange AHAR Reports)
As of FY 2018 the AHAR data submission process for CoCs has been replaced by the Longitudinal Systems Analysis (LSA) report submitted via the Homelessness Data Exchange, version 2.0.
