The Urban Institute released a new interactive map on March 3, as part of its Housing Assistance Matters initiative. Using data from the American Community Survey (ACS) Public Use Microdata Sample (PUMS), the map highlights the gap between the number of extremely low income (ELI) households and the number of affordable and available rental units, by county, for 2000, 2006, and 2012. The map underscores that there is no county in the United States with a sufficient number of rental units affordable and available to ELI households.
The interactive map also shows the impact of HUD rental assistance on the number of rental units affordable and available to ELI households. Using data from HUD’s Picture of Subsidized Housing, the researchers estimate the number of HUD-assisted units affordable and available to ELI households for each county. Without HUD rental assistance, the researchers estimate that there would be just one affordable and available rental unit for every 100 ELI households in the United States.
The researchers use 1-year ACS data to estimate the number of rental units affordable and available to ELI renters at the county level. The 1-year ACS PUMS file represents a 1% sample of the total U.S. population, or approximately 1.3 million housing units. Due to a small sample size in rural areas, the estimated gap of affordable and available units may be identical across adjacent rural counties.
