In 1972, an estimated 90 percent of the population in the United States identified as Christian. By 2020, this number dropped down to 64 percent, a phenomenon which may be attributed to recent trends where many Americans have left Christianity to instead identify as atheist, agnostic, or nothing in particular. If these trends continue, the number of Americans who are Christian has been projected to fall to 35 percent by 2070.
Projected share of Americans who identify as Christian in the United States in 1972, 2020, and 2070, if recent trends continue
*Projection for 2070 is based on whether recent trends of Americans leaving Christianity continue in the United States, with no limit imposed on switching rates.
