What this measures

Catholic members as a share of the population. They are counted from church records kept by each diocese, which makes this one of the study's most complete figures. Source: .

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.
