There are two types of communities that submit data to the AHAR: sample sites and contributing communities.
Sample sites were selected as part of the AHAR’s nationally representative sample of communities, and there are 102 sample sites in the AHAR. All sample sites are Community Development Block Grant (CDBG) jurisdictions, which constitute the basic building blocks of CoCs. In some cases, the CDBG jurisdiction and the CoC represent the same geographic area (e.g., principal cities are often a single CoC), but, in other situations, the CDBG jurisdiction is a geographic subunit of the CoC (e.g., a small city with 50,000 or more people may be a subunit of a countywide CoC). Sample sites submit AHAR data for those residential service providers located within the CDBG jurisdiction, even if the jurisdiction is a sub-geography of the larger CoC.
Contributing communities are typically CoCs, and the data from contributing communities should account for all residential service providers in the CoC. There are a few exceptions—i.e., when one or more sample sites are located within a CoC and the balance of the CoC submits data to the AHAR as a contributing community—but these situations are uncommon. Search for the keyword “sample sites” in the AHAR FAQ database for more information about how CoCs with sample sites can submit data that cover the sample site and the balance of the CoC.
Questions regarding sample sites and contributing communities should be directed to your AHAR liaison or you can submit a question through the Ask a Question function on the HUD Exchange.
