A new study released Monday found there has been a big drop since 2007 in the number of Americans who identify as Christian, according to the Pew Research Center. Though seven in 10 Americans still describe themselves as Christian, more people are identifying with no religion at all. The survey found Americans who call themselves atheist, agnostic, or of no particular faith jumped from 16 percent in 2007 to nearly 23 percent in 2014. In the same period, Christians dropped from 78 percent to just under 71 percent of the population.
