USPS Vacancy Data

HUD has entered into an agreement with the United States Postal Service (USPS) to receive quarterly aggregate data on addresses identified by the USPS as having been "vacant" or "No-Stat" in the previous quarter. HUD is making these data available for researchers and practitioners to explore their potential utility for tracking neighborhood change on a quarterly basis. The potential power of these data is that they represent the universe of all addresses in the United States and are updated every three months. Under the agreement with the USPS, HUD can make the data available publicly at the Census Tract level provided users agree to the terms and conditions of the click-on sublicense.
