And the recent "gold standard" survey , the General Social Survey (GSS) funded by the National Science Foundation, makes the point.
From Religion News Service:
...we see between a one and three point rise in secularity since 2012, with 7.5 million more people never entering a church or other worship service than just two years earlier....The number of Americans who never darken a church door is also at a new high. Over a third of Americans (34 percent) never attend a worship service (other than weddings and other ceremonies). This is a 3.4 point increase from just a few years earlier. Put differently, the group of Americans who don’t attend church grew by a rate of over ten percent in two years.
