ACS five-year survey estimates; not live data. Each measure retains its own period and denominator. Income is in the final year’s inflation-adjusted US dollars. Missing is not zero.
Same-period state estimates are context, not a statistical significance test or a rating.
Home values describe owner-occupied homes, not recent sale prices. Gross rent is monthly and includes applicable utilities; it is not advertised rent.
Households include family and nonfamily households and correspond to occupied housing units. Housing units also include vacant units. Neither counts people, postal addresses or homes for sale; do not add overlapping areas.
Selected fields; unavailable codes normalized to missing. No endorsement implied.

Dots summarize approximate ZIP locations grouped by state and three-digit prefix; they are not official delivery boundaries. Colors follow the first digit. Not every number in a displayed range is assigned. Alaska and island insets are relocated and use different scales.
Locations use available coordinates, not delivery boundaries. The simplified world outline may omit small islands; postal associations do not imply administrative ownership.
County outlines are simplified 2017 Census reference geography, not current legal or ZIP delivery boundaries. Highlighting follows postal associations.
No reliable coordinates are available for this postal region.
