In 1987, the year of the first American Catholic Laity survey, nearly half of American Catholics said that faith was “the most” or “among the most” important parts of their life. Now, only 37% say the same. Others are leaving the Catholic Church completely. The General Social Survey, a national survey conducted every year or two since the 1970s, asks people about the faith they grew up with, as well as their present religious identity. According to our analysis of its data, in 1973 only 10% of Americans who grew up Catholic had changed religions, and another 7% had left religion altogether. By 2018, each of those percentages had increased to 18%.
