Methodology: The U.S. Census American Community Survey provided demographic and economic data, including total population, number of residents age 65 and older, total households and median household income. Cost-of-living indexes were sourced from Sperling’s BestPlaces. Average expenditure estimates for retired households came from the Bureau of Labor Statistics’ Consumer Expenditure Survey, allowing for city-specific spending calculations. Housing costs were based on average single-family home values from the Zillow Home Value Index. Assuming a 10% down payment and the national 30-year fixed mortgage rate (sourced from Federal Reserve Economic Data), average monthly mortgage payments were estimated for each city. By combining housing and other essential expenses, the study calculated the total cost of living for basic necessities. Social Security income figures — for individuals and married couples filing jointly — were drawn from the Social Security Administration’s Monthly Statistical Snapshot. All data is current as of Oct. 23, 2025.
