This chart shows that religion in the United States is experiencing some difficulties. In the seven years since 2007, all three major christian groups have lost membership -- evangelicals about 0.9%, mainline protestants about 3.4%, and catholics about 3.1%. The only two groups that experienced growth are the non-christian religions by about 1.2 % and the non-religious by a whopping 6.7%.
The growth of the non-religious in the last seven years has been remarkable -- and has boosted them from 4th place among the groups to 2nd place now (vaulting them past the mainline protestants and the catholics). There is no reason to believe these trends won't continue.
The chart was made from information provided by the Pew Research Center.
