A Qualified Census Tract (QCT) is any census tract (or equivalent geographic area defined by the Census Bureau) in which at least 50% of households have an income less than 60% of the Area Median Gross Income (AMGI). HUD has defined 60% of AMGI as 120% of HUD's Very Low Income Limits (VLILs), which are based on 50% of area median family income, adjusted for high cost and low income areas.

This service denotes the locations of colonias communities as defined in Section 916 of the Cranston-Gonzalez National Affordable Housing Act of 1990. In order to better serve colonia residents, the National Affordable Housing Act of 1990 (as amended) included Section 916 which called for the border states of Arizona, California, New Mexico and Texas to set aside a percentage of their annual State CDBG allocations for use in the colonias. The use of these set aside funds is to help meet the needs of the colonias residents in relationship to the need for potable water, adequate sewer systems, or decent, safe and sanitary housing. Therefore, the set-aside funds may be utilized for any CDBG eligible activity that is, or is in conjunction with, a potable water, sewer or housing activity.

Community Development Block Grant (CDBG) eligible and ineligible census tracts. The U.S. Department of Housing and Urban Development requires local municipalities that receive CDBG formula entitlement funds to use the 2011-2015 ACS LMISD data file to determine where CDBG funds may be used for activities that are available to all the residents in a particular area. A CD-eligible census tract refers to 2010 census tracts where the area is primarily residential and at least 51.0% of the residents are low- and moderate-income as per the LMISD data file. For New York City, a primarily residential area is defined as one where at least 50.0% of the total built floor area is residential as determined by PLUTO 18v2.1. Low- and moderate-income persons are defined as persons living in households with incomes below 80 percent of the area median household income (AMI). The New York Primary Metropolitan Statistical Area's AMI was $70,300 for a 4-person family at the release of the 2011-2015 American Community Survey.

HUD's Community Challenge Grants aim to reform and reduce barriers to achieving affordable, economically vital and sustainable communities. The funds are awarded to communities, large and small, to address local challenges to integrating transportation and housing. Such efforts may include amending or updating local master plans, zoning codes, and building codes to support private sector investment in mixed-use development, affordable housing and the re-use of older buildings. Other local efforts may include retrofitting main streets to provide safer routes for children and seniors, or preserving affordable housing and local businesses near new transit stations.

Low-Income Housing Tax Credit Qualified Census Tracts must have 50 percent of households with incomes below 60 percent of the Area Median Gross Income (AMGI) or have a poverty rate of 25 percent or more. Difficult Development Areas (DDA) are designated by the U.S. Department of Housing and Urban Development and are based on Fair Market Rents, income limits, the 2010 census counts, and 2006–10 5-year American Community Survey data when they becomes available. Beginning with the 2016 DDA designations, metropolitan DDAs will use Small Area Fair Market Rents (FMRs) rather than metropolitan-area FMRs for designating metropolitan DDAs. Maps of Qualified Census Tracts and Difficult Development Areas are available at: huduser.gov/sadda/sadda_qct.html. 2023 IRS SECTION 42(d)(5)(B) METROPOLITAN DIFFICULT DEVELOPMENT AREAS (OMB Metropolitan Area Definitions, September 14, 2018 [MSA] and derived FY2022 HUD Metro SAFMR Area Definitions [HMFA])

This service denotes the service areas for HUD's Homeownership Centers (HOCs) which help insure single family Federal Housing Administration (FHA) mortgages, and oversee the selling of HUD homes. Processing for much of the Single Family FHA mortgages is centralized into one of four Homeownership Centers (HOC) located in Atlanta, Philadelphia, Denver, and Santa Ana; each supporting specific geographic region. Although most questions are handled by the FHA Resource Center (not the HOC) for immediate acknowledgement and tracking, certain case specific issues will subsequently be referred to the appropriate center.

To assist communities in identifying racially/ethnically-concentrated areas of poverty (R/ECAPs), HUD has developed a census tract-based definition of R/ECAPs. The definition involves a racial/ethnic concentration threshold and a poverty test. The racial/ethnic concentration threshold is straightforward: R/ECAPs must have a non-white population of 50 percent or more. Regarding the poverty threshold, Wilson (1980) defines neighborhoods of extreme poverty as census tracts with 40 percent or more of individuals living at or below the poverty line.
