Irreligion, which may include deism, agnosticism, ignosticism, anti-religion, atheism, skepticism, ietsism, spiritual but not religious, freethought, anti-theism, apatheism, non-belief, pandeism, secular humanism, non-religious theism, pantheism and panentheism, varies in the countries around the world. According to reports from the Worldwide Independent Network/Gallup International Association's (WIN/GIA) four global polls: in 2005, 77% were a religious person and 4% were "convinced atheists" while in 2012, 23% were not a religious person and an additional 13% were "convinced atheists";[2] in 2015, 22% were not a religious person and an additional 11% were "convinced atheists";[3] and in 2017, 25% were not a religious person and an additional 9% were "convinced atheists".[4]
According to sociologist Phil Zuckerman, broad estimates of those who have an absence of belief in a God range from 500 to 750 million people worldwide.[5] According to sociologists Ariela Keysar and Juhem Navarro-Rivera's review of numerous global studies on atheism, there are 450 to 500 million positive atheists and agnostics worldwide (7% of the world's population), with China having the most atheists in the world (200 million convinced atheists).[6]
Each poll uses different questions and methods:-
The numbers come from different years, and might not be accurate for countries with governments that require or urge religion or secularism.
The WIN-Gallup International Association (WIN/GIA) poll results below are the totals for "not a religious person" and "a convinced atheist" combined. Keysar et al. have advised caution with WIN/Gallup International figures since more extensive surveys which have used the same wording for decades and have bigger sample sizes, have consistently reached lower figures. For example, the WIN/GIA numbers from China were overestimated which in turn inflated global totals.[6]
