A 2023 poll by the Pew Research Center found that 4% of Americans in the United States self-identified as atheists.[4] This is an increase from 3.1% of Americans in 2014.[3] However, in 2014, 9% of Americans agreed with the statement "Do not believe in God" while 2% agreed with the statement "Do not know if they believe in God".[3] According to a poll by non-profit PRRI in 2023, 4% of Americans were atheist and 5% were agnostic.[5] Polling by Gallup in 2022 showed that 17% of respondents replied "No" when asked "Do you believe in God?" in a binary fashion, but when worded differently in 2023, Gallup found that 12% of respondents replied they "Do not believe in" God and 14% replied they were "Not sure about" the existence of God.[6] According to Gallup, there are variations in their polling results because they ask about God in three different wordings, each with a different result.[7]
American atheists
Total population
56,000,000 (17%) (answered "No" to the question "Do you believe in God?") (2017)[1] 9,571,112 (3.1%) (self described atheists) (2014)[2][3]
According to the 2014 General Sociological Survey, the number of atheists and agnostics in the U.S. grew over the previous 23 years. In 1991, only 2% identified as atheist, and 4% identified as agnostic; while in 2014, 3.1% identified as atheists, and 5% identified as agnostics.[8]
According to the 2008 ARIS, only 2% the US population was atheist, while 10% were agnostics.[9]
One 2018 research paper using indirect methods estimated that 26% of Americans are atheists, which is much higher than the 3%-11% rates that are consistently found in surveys.[10] However, methodological problems have been identified with this particular study; in particular, it has been posted that many people might not have a binary outlook to the question of the existence of God.[11]
Accurate demographics of atheism are difficult to obtain since conceptions of atheism and self-identification are context dependent by culture.[12] In 2009, Pew stated that only 5% of the US population did not have a belief in a god and out of that small group only 24% self-identified as "atheist", while 15% self-identified as "agnostic" and 35% self-identified as "nothing in particular".[13] In 2023, Pew stated that 23% of atheists believe in a higher power, but not a god.[14]
A June–September 2014 Pew Research Center survey found that 69% of atheist Americans identity as Democratic or lean Democratic, 17% have no lean, 15% identify as Republican, 56% liberal, 29% moderate, 10% conservative, and 5% don't know. Among Americans who don't believe in god/gods, 65% identity as Democratic or lean Democratic, 17% have no lean, 18% identity as Republican, 50% liberal, 31% moderate, 13% conservative, and 6% don't know. That makes atheist and nonbelievers in god/gods Americans as belief groups to be the most politically liberal belief group in America and the least politically aligned belief group with Republicans and conservatism in the United States.[3]
Views about atheists
In 2014, a Pew survey found that 53% of Americans claimed they would be less likely to vote for a presidential candidate who was an atheist.[28]
Groups that include atheists
A October 2013 Public Religion Research Institute American Values Survey found 58% of American libertarians report they believe in a personal god, 25% believe god is an impersonal force in the universe, and 16% report that they do not believe in a god. It also found 73% of Americans who identify with the Tea Party report they believe in a personal god, 19% believe god is an impersonal force in the universe, and 6% report that they do not believe in a god. It also found 90% of white evangelical Protestants report they believe in a personal god, 8% believe god is an impersonal force in the universe, and less than 1% report that they do not believe in a god.[29]

Laurence Moore and Isaac Kramnick, Godless Citizens in a Godly Republic: Atheists in American Public Life, Norton, 2018; and John Gray, Seven Types of Atheism, Farrar, Straus & Giroux, 2018, which defines "atheist" as "anyone with no use for a divine mind that has fashioned the world" (a category that includes nontheist religions with no creator god, such as Buddhism and Taoism).

Studies suggest that some 26 percent of Americans – more than 64 million people – are atheists.
