Derived statistics

  • ZIP pages use Census ZIP Code Tabulation Areas (ZCTAs), not USPS delivery routes.
  • Population density is computed as population ÷ land area.
  • Overlap percentages (tracts and districts) are derived from map geometry and are approximate.

Data accuracy & methodology

ZIP pages combine 2020–2024 ACS 5-year ZCTA estimates with other public datasets when available (see Sources). Connectivity metrics use FCC coverage data, not ACS. ZIP-level estimates can have higher margins of error than county/state totals; treat small differences as statistical noise rather than precise changes.
