The charts in this post were made from a Pew Research Center survey released on December 30th (although it was done between March 21st and April 8th). The survey questioned a random nationwide sample of 1,983 adults, and has a margin of error of 3 points.
The charts below show a demographic breakdown of Americans who believe in evolution and those who don't. Note that the white evangelicals are the only group showing a significant majority not believing in evolution. Republicans and Black protestants are split on the matter. All other groups have significantly more people believing in evolution than denying it.
