“Compared to the U.S. population overall, nonreligious Americans are younger and more Democratic-leaning. But the number of Americans who aren’t religious has surged in part because people in lots of demographic groups are disengaging from religion — many nones don’t fit that young, liberal stereotype. The average age of a none is 43 (so plenty are older than that). About one-third of nones (32 percent) are people of color. More than a quarter of nones voted for Trump in 2020. And about 70 percent don’t have a four-year college degree.”
