The “We’re a Christian nation” talking point takes another kick in the pants:

Christianity is still the dominant faith by far in the U.S.; 7 in 10 Americans identify with the tradition. However, the ranks of Christians have declined as the segment of people with no religion has grown, the survey says.

Between 2007 and 2014, when Pew conducted two major surveys of U.S. religious life, Americans who described themselves as atheist, agnostic or of no particular faith grew from 16 percent to nearly 23 percent. At the same time, Christians dropped from about 78 percent to just under 71 percent of the population. Protestants now comprise 46.5 percent of what was once a predominantly Protestant country.
