The populations of Latin America are almost exclusively Catholic. Not just that they are Catholics, but they are also one of the most devoted Catholics in the world, where the rates of atheism are almost zero, and the intrusion of other religions is almost impossible. Since the largest portion of the migrants that came in the United States in the past 50 years are from Latin America, it is safe to say that the Catholic religion is the one that has the highest increase in membership in the country. Not that the Latin Americans are comprising the highest percentage of migrants in the United States, but they also have higher birthrates than most of the other groups, so that is further increasing the membership of the Catholic religion.
