That many Catholics in AK and CA??? That surprises me.
Sounds right to me... we Catholics are used to suffering.
I can't take this map too seriously. California is Catholic only in that it has a lot of hispanics. This map paints with too broad a brush -- Some of the largest evangelical churches are in southern California, but you'd never know it by this map. It may have some usefullness, but it can also be quite misleading.
Looks like southwest. Russians got the major foothold there.
