Normalized score = clamp(120 − Numbeo Cost of Living Index, 0, 100). A lower cost index produces a higher lifestyle score.

Raw ratio = median owner-occupied housing value ÷ median household income. Normalized score = clamp(100 − (ratio − 2) × 10, 0, 100).

Uses Numbeo's city Safety Index directly on a 0–100 scale. Community-contributed index; interpret alongside official local crime data.

Normalized score = clamp((labor-force participation − 55) ÷ 25 × 100, 0, 100). This is a participation proxy, not an unemployment rate.

Normalized score = clamp((median household income − $45,000) ÷ $85,000 × 100, 0, 100). Values are not adjusted for the city's cost of living in this metric.

Normalized score = clamp((bachelor's attainment − 20) ÷ 55 × 100, 0, 100).

Normalized score = 100 − uninsured share under age 65. This reflects insurance coverage, not care quality or access by itself.

Composite = 55% commute-time score + 45% Transit Score. Commute score = clamp((45 − mean commute minutes) ÷ 25 × 100, 0, 100).

Uses the published Walk Score city ranking directly on a 0–100 scale. Marked stale because the referenced ranking vintage is 2021.

Uses Numbeo's Climate Index directly. The index summarizes comfort-oriented temperature and humidity conditions; it is not a climate-risk score.

Normalized score = 100 − Numbeo Pollution Index. This is a broad community-contributed pollution measure and should later be supplemented with EPA monitor data.

Proxy score from accommodation and food-service sales per resident. Normalized score = clamp((sales per resident − $3,000) ÷ $7,000 × 100, 0, 100).

Composite = 45% child-population presence + 35% inverse poverty + 20% insurance coverage. This is a broad readiness indicator, not a school-quality rating.

Composite = 55% broadband readiness + 45% educational attainment. Broadband is normalized over 80–98%; bachelor's attainment over 25–70%.

Composite = 40% climate index + 35% Bike Score + 25% inverse pollution score. It measures outdoor convenience, not park acreage or trail access.
