About the NHPD

The National Housing Preservation Database (NHPD) is the only de-duplicated source of address-level data for nearly 80,000 federally supported housing properties in the U.S. Founded by the Public and Affordable Housing Research Corporation (PAHRC) and the National Low Income Housing Coalition (NLIHC), the NHPD helps users access vital information to better understand the stock of publicly supported housing in their community, and to preserve affordable housing options for low-income households. The NHPD integrates information from ten separate federal housing programs and other U.S. Department of Housing and Urban Development (HUD) administrative data, and is updated for times per year.

Since its inception in 2012, the NHPD has been featured in over 50 major media and research publications, such as USA Today, NY Times, Bloomberg Business, Harvard University, the Urban Institute, New York University, and the University of California Los Angeles.

  • Custom tabulations: Request local data in relation to preservation risks, exposure to natural hazards, and neighborhood opportunity for the federally assisted housing stock.
  • Policy background: Leverage our housing policy knowledge to contextualize the affordable housing stock's preservation risks.
