Though the number of Americans who believe in God has declined some since the 1960s, a vast majority continue to say they believe in a higher power. In 1968, 98% of Americans said they believed in God. Gallup's most recent study found that number remains an overwhelming majority: 89%.
In a study conducted June 14-23, Gallup asked Americans about faith in two different ways, both earning the same result. Asked "Do you believe in God?" and "Do you believe in God or a universal spirit?" 89% of those polled said "yes" to both.
|Do you believe in God?||89||10||1|
|Do you believe in God or a universal spirit?||89||9||2|

Another version of the question asked in a May 4-8 survey found that 79% said the definitely "believe in" God, while 10% said they were "not sure about" God, and 11% said they "don't believe in" God.

Gallup's 89% result is a 7% drop from 1944 when they first asked the question and a 9% drop from the 1960s, when around 98% of Americans said they believed in God.
Gallup added the modified question including the "universal spirit" as an option in 1976. Over the following decades, the responses to the two versions of the question were close, but not always exactly the same.
Starting in 2001, Gallup has included in some surveys the "not sure about" option, which has continued to get relatively similar results (ranging from 7 to 11%), while the "believe in" response" has declined from 90 to 79% during that time.
When Gallup asked in May about specific spiritual beliefs, the results varied significantly. While 79% said they believed in God, only 71% believed in Heaven, and even fewer, 64%, believed in Hell and the devil, 61%.
Overall, Gallup has found a slight decline in belief in God and the spiritual world since it began asking Americans in the 1940s. "The exact meaning of these shifts is unclear," Gallup concludes. "Although the results can be taken at face value in showing that fewer Americans believe in God than did so in the past, it is also possible that basic beliefs have not changed -- but rather Americans' willingness to express nonreligious sentiments to an interviewer has."
