Where does PlainZIP source state ZIP data?
Counts and demographics come from the U.S. Census Bureau American Community Survey 5-Year Estimates and ZIP Code Tabulation Area geography. PlainZIP aggregates federal survey rows; it does not publish relocation advice or neighborhood quality scores. See the methodology page for extract vintage and ACS vs ZBP overlap notes.
This page explains the source records, calculation, and limits behind the figures shown.
State ZIP counts and population totals are SUM/COUNT aggregations of ZIP Code Tabulation Area rows, not separately published state summaries. Mean ZIP income ranks use unweighted averages of ZIP-level ACS median household income, they reconcile to the ZIP detail pages. Read our editorial standards and corrections policy,
