U.S. Geography Crosswalk (ZIP ↔ County ↔ CBSA ↔ State)
The crosswalk from every U.S. ZIP code to its county, metro area (CBSA) and state, with population and location, from a single 2020 Census vintage. ZIP-to-county is a best-fit assignment, and the county FIPS code is not the CMS SSA county code.
What Vlada adds: Integrates and normalizes multiple public inputs into a queryable Vlada data product with source-traced lineage.
