Younger adults (those under the age of 50) are less inclined than older Americans to believe in a biblical God and more likely to say they don’t believe in any higher power or spiritual force. While roughly two-thirds of older adults say they believe in the biblical God, just 49% of those in their 30s and 40s – and just 43% of adults under 30 – say the same. Even with this age gap, an overwhelming majority of the youngest adults continue to believe in God or a higher power: Eight-in-ten of those ages 18 to 29 say they believe in at least some kind of spiritual force.
