Americans' belief in God falls to new low of 81%: poll

The number of U.S. adults who say they believe in God has dropped to an all-time low of 81%, with liberals and young people less likely to profess a belief in a higher being, according to a Gallup poll released Friday.

When Gallup first asked "Do you believe in God?" in 1944, 96% of Americans said yes. 2011 was the last year more than 90% of U.S. adults said they believed in God, with 92% saying yes. Belief in God has stayed below 80% ever since.

Conservatives are the most likely group to express belief in God, with 94% saying that they have faith. People of color are also more likely to profess belief in a higher power than non-Hispanic white people at 88% to 79%.

Women are slightly more likely than men to say they believe in God at 83% to 80%.

Married people are also more likely to say they believe in God than those who are not married at 88% to 77%. 

Just 68% of people who are 18-29 years old say they believe in God, making them the least likely age group to do so. This is down by 10 points from 2013-2017.

Liberals and Democrats are the least likely groups to profess belief in a higher power, at 62% and 72%, respectively.
