Sources & methodology

Each observation retains its source, definition and reference year. Population estimates differ from census counts: four island territories use 2020 census counts, while other profiles use the supplied 2025 estimates. Area uses 2025 Census Gazetteer geography for states, DC and Puerto Rico, and 2010 geography for four Island Areas. ACS socioeconomic observations are 2025 sampling estimates; margins of error use 90% confidence. A calculated poverty rate has no calculated margin of error. Comparisons include only matching facts and years. Source controls and dates open individual source cards; the source-record list stays collapsed. Display conversions retain original measurements in the source card. Further subject research is in progress; empty sections are omitted.
