According to the U.S. Census Bureau's 2023 American Community Survey (ACS) 5-year estimates, PlainCities renders standardized city-level demographic, income, education, employment, and housing indicators across more than 19,000 incorporated places nationwide. Population counts and median household income figures are sourced directly from Census Table B01003 and B19013 respectively, with poverty rates from B17001 and cost-of-living adjustments from the Bureau of Economic Analysis (BEA) Regional Price Parities (RPP) 2024 release. Every value displayed in this snapshot links back to the official upstream tables and is refreshed on the ACS annual release cadence (typically December of the survey year + 1).

Methodology: city boundaries follow the Census Bureau's place-level geography (incorporated places, census-designated places, and consolidated city-county governments), with FIPS codes ensuring consistent identifiers across decennial and annual surveys. Cost-of-living comparisons use BEA's Regional Price Parities (RPP) indexed to the national average (100), enabling cross-city purchasing-power comparisons. See our methodology page for full source attribution, refresh cadence, and known data quality limitations including margin-of-error disclosure and sample-size thresholds.
