USPS Vacancy Data

Ongoing research banner


Through an interagency agreement with the United States Postal Service (USPS), HUD receives counts of total and vacant business and residential addresses in the United States at the ZIP+4 (ZIP9) geographic level. HUD uses these data for a variety of purposes, including research on neighborhood change; tracking disaster recovery; gauging the foreclosure crisis; analyzing housing markets; and measuring the impact of HUD funding on communities for programs such as the HOME Investment Partnership Program (HOME), the Community Development Block Grant (CDBG) program, the American Dream Downpayment Initiative (ADDI), and the Self-Help Homeownership Opportunity Program (SHOP). HUD is also permitted to make the vacancy data available at the census tract level to government and nonprofit organizations through a permitted user sublicense agreement. Permitted sub-licensees access these data through www.huduser.gov via a pass-word-protected portal. HUD has received these data quarterly since December 2005.

Note: The status of this project is ongoing.
