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.

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.
