Rain and melted snow over the year, averaged over the whole area. An average over area, so combined areas are weighted by their size.

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.

MeasureUnadjustedAdjusted
Yearly precipitation and Area in droughtWhere Yearly precipitation is higher, Area in drought tends to be lower: a moderate link that holds when only places with similar density, income and education are compared, and inside states as well. Area in drought by US county-0.48-0.41
Yearly precipitation and Weeks with half the area in droughtWhere Yearly precipitation is higher, Weeks with half the area in drought tends to be lower: a moderate link that holds when only places with similar density, income and education are compared, and inside states as well. Weeks with half the area in drought by US county-0.47-0.40
Yearly precipitation and Adult income rank of children raised poor hereWhere Yearly precipitation is higher, Adult income rank of children raised poor here tends to be lower: a weak link that holds when only places with similar density, income and education are compared.

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.

Share of residentsUnadjustedAdjusted
Yearly precipitation and Share White, not HispanicCould easily be chance once only places with similar density, income and education are compared. Share White, not Hispanic by US county-0.06+0.02

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.
