Average temperature
The average temperature over the year, in degrees Fahrenheit, across the whole county or state. NOAA builds it from weather station readings, filling the gaps between stations with a map of the area, and averages the twelve monthly figures. One unusually warm or cold year can stand out, so look at several years.

What it goes with
The strongest links that have a page of their own. Unadjusted is the link before adjusting for anything, from −1 (opposite) to +1 (in step). Adjusted compares places with the same population density, income and education levels, so those differences can’t explain the link. This list leaves out the 0 pairs built from the same numbers or the same model as this measure, since they are bound to match.

Population makeup
How this measure varies with the racial and ethnic makeup of counties. Every group is shown, whatever its rank. These are links across counties: they describe places, not people. They say nothing about any person’s risk or behaviour based on their race. Counties with a larger share of one group also differ in much else, such as income, segregation, region and history. The adjusted figure only accounts for density, income and education.

Highest and lowest
Of 3,143 counties reporting it. These are the two ends of a national ranking. For most measures, that ranking mostly sorts places by income and how urban they are. That is why the place pages compare each place with similar places instead.

- Monroe County, FL — 78.4
- Miami-Dade County, FL — 78
