About this bundle
One purchase, four ready-to-use data packs, each in CSV, JSON and SQLite with a data dictionary for every column, a licence and attribution file, a changelog and a validation report.
You get: the US Geography Crosswalk (ZCTAs, counties, places, metro areas, states), the County and ZCTA Demographic Snapshot (ACS 2020-2024 5-year estimates with margins of error), World Airports, Countries and Currencies (OurAirports, Wikidata and Natural Earth joined by ISO code), and the US FIPS Code Lookup Pack (state, county, county subdivision, place and AIANNH codes, regions, divisions and county adjacency). The U.S. packs use the same zero-padded county and ZCTA keys, so they join to each other.
ZCTAs are Census approximations, not USPS ZIP Codes. The bundle has no area codes and no time zones. Independent product by Quietcog; not official and not endorsed by the Census Bureau, USPS, OurAirports, Wikidata, Natural Earth or any other source.
