Summary

US citizens belief in God remains strong, between 80-90%. Church affiliation has declined to 70%. Mainline (liberal-centrist) Protestant believers have declined dramatically, but recently stabilized. Evangelical Protestant believers increased in the 1980’s and 1990’s, but have declined somewhat since then. Catholic membership has remained roughly constant, with Hispanics replacing Whites.

The decline in Whites as a percentage of the US population, combined with the increase in non/other believers has lead to headlines proclaiming the end of a majority White Christian America. This is true statistically, with politicians attempting to take advantage of the situation.
