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.
