When you map the primary religion in every county in America, the Catholics stand out.
As America’s single-largest religious group, Catholics show up everywhere, from the Italian alleyways of New England to the thriving Filipino churches of Hawaii, from the Polish pockets of the Rust Belt to the Cuban corners of South Florida. Then there’s Acadian Louisiana and, of course, the massive swath of the American West that used to be Mexico — which, as you may know, is pretty Catholic.
