Based heavily in the south, the key distinguishing characteristic for these 372 counties is the high number of religious adherents tied to evangelical churches like the Southern Baptist Convention. But the Evangelical Hubs have a few other key elements driving their community culture – they are less diverse (85% white), with lower incomes (a median of about $39,000) and lower education levels (about 15% of the population have a bachelors degree or more). They are also one of the most politically conservative types in the American Communities Project. Mitt Romney won 69% of the vote from these places.
