USPS Data Enhancement


Ongoing research banner

Since 2005, the United States Postal Service (USPS) has provided HUD with administrative address data including counts of residential and business addresses not collecting mail delivery which is used as a proxy to measure vacancy. HUD processes this data to provide national-in-scope census tract-level aggregations of counts of addresses and vacant housing to qualified researchers, non-profits, and government organizations. There are two goals of the USPS Data Enhancement. The first goal of the USPS data enhancement is to provide users with a tool to query longitudinal address data in specific neighborhoods and include neighborhood characteristics from data linkages such as the American Community Survey (ACS) or machine learning methods measuring neighborhood change. The second goal of the USPS data enhancement is to provide a measure of the share of addresses that are served by rural postal carrier routes. Addresses listed as "no-stat" served by rural postal carrier routes may be vacant addresses, per guidance from the USPS. The purpose of this data enhancement is to provide researchers and analysts with a potentially more accurate estimate of vacant addresses. The project is expected to be completed in 2023.

Note: The status of this project is ongoing.
