How We Rank the Best Places to Live

Our livability score combines four data-driven factors: affordability (35% — cost of living index relative to national average), income (25% — median household income from the Census Bureau), housing value (15% — home price to income ratio), and climate (15% — NOAA temperature normals favoring moderate climates). Population serves as a proxy for amenities (10%).

Only cities with at least 5,000–10,000 residents are included. Data sourced from the US Census Bureau, Zillow, HUD, and NOAA.
