‘America is only 10 to 25 years behind Europe in this regard.’
Really? I can see five European countries who attend church more than America?

Within the United States, there are wide variances in church attendance, with the figures in the Pacific Northwest and the northern Rocky Mountain states (excluding Utah) and the New England states being quite low, vs. much higher figures in the South and the Plains states. Dallas and Nashville are far different than Seattle or Boston, as Poland and rural Ireland are from Moscow, Berlin, or London. Furthermore, of the largest Western European nations listed (Germany is oddly absent from the list) in the EU, only Italy has a church attendance rate (45%) comparable to that of the United States. Look at France (21%), Britain (27%), and Spain (25%), and you can determine that the EU average is considerably below that of the US.
