The AHAR contains data from two sources. The first source is HMIS data. The AHAR is based largely on the universal data elements in HUD’s HMIS Data Standards. All HMIS data are reported in the aggregate to the research team. At present, the data represent any person who enters an emergency shelter, transitional housing, and/or permanent supportive housing during a 12-month reporting period, from October 1 to September 30 of the following year. Since 2010, the AHAR has included people served in permanent supportive housing projects. Data are reported separately for individuals and persons in families in these project types.
The AHAR also includes Point-in-Time (PIT) count data, which gives a “snapshot” of people experiencing sheltered and unsheltered homelessness on a single night in January. The annual PIT count data also provide information on the numbers of homeless people within particular population groups, such as people experiencing chronic homelessness, severe mental illness, substance abuse, veterans, unaccompanied youth, or those living with HIV/AIDS. Lastly, the AHAR to Congress includes bed inventory information from the Housing Inventory Charts (HIC) and is tabulated at the national level.
