4. Less Catholics and Protestants Than Ever in America
Recent studies suggest that there are now more religiously unaffiliated Americans than Catholics or traditional Protestants. The non-religious amount to 25 percent of the American population, compared to 21 percent for Catholics and 15 percent for Protestants. And also notable is that the numbers of American Catholics and American Protestants have both shrunk between 3 and 5 percentage points over the past eight years, while the number of evangelicals has also shrunk by 1 percent.
