Protestants are just about to slip down into minority status, according to this report. “Whereas nearly two thirds of Americans identified themselves as Protestant as recently as the 1980s, only 51 percent identify as Protestant today, the study found.” (For a more in-depth discussion of the survey results, read this.)
The major reason is not a surge in the number of Catholics. That church body is losing members faster than any other, except that large numbers of legal and illegal immigrants, most of whom are Catholics, are keeping the numbers up to pretty much what they have been. The biggest factor is the rise of the fastest-growing religious category: the “unaffiliated,” which now numbers 16%. Evidently, people who once went to churches are abandoning them.
