ZBP ZIP rows

30,507 ZIPs sit in both universes. The comparison tool reads ACS demographics and ZBP establishments from the same published rows; it does not score or recommend places.

Source: U.S. Census Bureau, American Community Survey 5-Year Estimates (2019–2023 claims window) and ZIP Code Business Patterns (2023), joined to the HUD-USPS ZIP crosswalk. ACS people counts and ZBP establishment counts are separate universes; the tools never divide one by the other.

This page explains the source records, calculation, and limits behind the figures shown. Every figure a tool displays is read from the published ZIP-level Census record and compared arithmetically. ACS demographics and ZBP establishments are separate universes. The tools do not score, rank or recommend places, and they cannot describe conditions on a particular street or in a particular year later than those vintages.
