Atlas layers use U.S. Census Bureau ACS 2020-2024 5-Year Estimates. Rent, owner cost, and home value are county medians. Cost score rewards lower rent and lower owner costs, but affordability still depends on income, household size, commute, debt, and personal finances. Use this as decision context, not personalized financial advice.
