How Many People Celebrate Christmas in the United States?

Although specific numbers aren't available, a 2013 survey by Pew Research Center showed that 96 percent of Christians in the United States celebrate Christmas, and the holiday is celebrated by 81 percent of non-Christians. Around 72 percent of U.S. adults professed to be Christians in 2012, which was a drop of 5 percent from 2007, according to Pew Research.

A 2010 Gallup poll found that 93 percent of Americans engaged in secular activities like spending time with friends and family on the holidays and exchanging holiday presents. Around 88 percent of Americans put up a Christmas tree.

The religious aspect of the holiday featured aspects that were practiced in numbers that inflated based on whether those polled identified as strongly religious, somewhat religious or not too religious. For example, 86 percent of those who identified as strongly religious practiced putting up religious-themed decorations, compared to only 25 percent of those who were self-identified as being not too religious. Those who were strongly religious were more apt to attend religious services on Christmas Day or Christmas Eve, and 98 percent of them reported taking time to reflect on the birth of Jesus Christ during the holiday season, compared to just 31 percent of those who were less religious.
