LIHTC Mapping Tool

Where are Low-Income Housing Tax Credit Units Located?

The Low-Income Housing Tax Credit (LIHTC) program has been a key component in the creation of affordable housing; in the 30 years since the program’s inception it has led to the development and financing of more than 3 million affordable apartment units.

LIHTC data from the U.S. Department of Housing and Urban Development (HUD) and demographic and housing data the U.S. Census’ American Community Survey (ACS) were used by the NAHB Economics and Housing Policy group to create a series of maps, which show the concentration of LIHTC units by census tract and categorizes each census tract by income: very low-income, low-income, moderate-income, or high-income.

These maps provide users with the opportunity to better understand the distribution of LIHTC housing in select Metropolitan Statistical Areas (MSAs) and allows users to easily identify census tracts that are underserved and offer affordable housing development opportunities.

Curious about how the NAHB LIHTC Mapping Tool works? Check out this short video that walks you through the tool.


Below is an example of the overall map and the detail drilldown for a Qualified Census Tract. In the mapping tool when hovering a mouse over each census tract, a “Census Tract Profile” will pop up. Included in each profile are the following variables: population, rental units, poverty rate, unemployment rate, share with high school diploma, median household income, median family income, and LIHTC unit share of rental housing.
