What this measures

The number of residents aged 25 and over. Education levels are measured for this age group, since most people have finished school by then. Source: Census ACS 5-year.

This is a count, so it is ranked per 1,000 residents. Ranked by the raw total, it would just list the biggest counties.

For most measures, a national ranking mostly sorts places by income and by how urban they are. Each county’s own page compares it with the 50 counties most like it instead, which is often the fairer view.
