How we score towns, and where the figures come from
How we score
- Cost of living: How expensive everyday life is compared with the rest of the US, adjusted for local rent, plus the typical rent.
- Jobs and income: Typical household income, how many people are out of work, and how many live in poverty.
- A place that is growing: How much the number of people and the typical income have grown between the two most recent Census survey periods (each covers five years).
- Home internet and working from home: How many homes in the county have fast internet, and how many people work from home.
- State taxes: Taxes each state government collects per resident: all taxes, income tax and sales tax (US Census). These are amounts collected, not what you would personally pay.
- Property taxes: The typical property tax homeowners pay, and that tax as a share of the typical home price (US Census).
- Housing affordability: Home prices compared with income, rent as a share of income, and the typical home price.
- Space and yard size: Rooms per home, how many homes are stand-alone houses, and how spread out people are. We do not have yard or lot sizes from free sources.
- Schools: The public schools located in the town: how many high-school students take AP/IB or college classes, how many students miss a lot of school, the graduation rate (older data) and class size. Child poverty is shown for context and is not scored. Towns with no high school or too little data are not rated. We do not have test scores yet.
- Diversity & community: The mix of racial and ethnic backgrounds, and the share of residents born outside the US.
- Health and medical care: Open hospitals in each town, family doctors, dentists and mental-health providers per person (county), and how many people have no health insurance.

- Safety: Homicides in the county (County Health Rankings) and the state rate of violent crime (FBI, when available).
- Clean air and low disaster risk: Fine-particle air pollution (county) and the risk of floods, storms, fires and other disasters (county, from FEMA).

- Pleasant weather for being outdoors: Days that are 65–85°F and dry, and hours of sunshine.
