vary considerably across different cultures and languages, ranging from an active concept to being unimportant or not developed. Also in some countries and regions atheism carries a strong stigma, making it harder to count atheists in these countries.
In global studies, the number of people without a religion is usually higher than the number of people without a belief in a
deity
A deity or god is a supernatural being considered to be sacred and worthy of worship due to having authority over some aspect of the universe and/or life. The ''Oxford Dictionary of English'' defines ''deity'' as a God (male deity), god or god ...
and the number of people who agree with statements on lacking a belief in a deity is usually higher than the number of people who self-identify as "atheists".

, broad estimates of those who have an absence of belief in a deity range from 500 to 750 million people worldwide as of 2006.
An earlier estimate stated that there were 200 million to 240 million self-identified atheists worldwide as of the year 2000, with China and Russia being major contributors to these figures.
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 alone accounting for 200 million of that demographic as of 2013.
Zuckerman, Galen and Pasquale estimated there were 400 million nonreligious or nontheistic people as of 2016.
Relative to its own populations, Zuckerman ranks the top five countries with the highest possible ranges of atheists and agnostics: Sweden (46–85%), Vietnam (81%), Denmark (43–80%), Norway (31–72%), and Japan (64–65%).

Enlightenment.
Discrepancies exist among sources as to how atheist and religious demographics are changing. Questions to assess non-belief may ask about negation of the prevailing belief, rather than an assertion of
positive atheism. Also, self-identification is not congruous to people's lack of beliefs automatically. For instance, merely not having a belief in a god, for whatever reason, does not automatically mean that people self-identify as an "atheist".
According to global
Win-Gallup International studies, 13% of respondents were "convinced atheists" in 2012,
11% were "convinced atheists" in 2015,
and in 2017, 9% were "convinced atheists".
Some global studies have indicated that
global atheism may be in decline due to irreligious countries having the lowest birth rates in the world and religious countries having higher birth rates in general.

Because some governments have strongly
promoted atheism and others have strongly
condemned it, atheism may be either over-reported or under-reported for different countries. The accuracy of any method of estimation is debatable, as there are opportunities to misreport (intentionally or not) a category of people without an organizational structure. Also, many surveys on religious identification ask people to identify themselves as "agnostics" or "atheists", which is potentially confusing, since these terms are interpreted differently; some identify themselves as
agnostic atheists. Additionally, many of these surveys only gauge the number of

Jack David Eller states that "atheism is quite a common position, even within religion" and that "surprisingly, atheism is not the opposite or lack, let alone the enemy, of religion but is the most common form of religion."

ists, may indulge in some religious activities as a way of connecting with their culture, all the while being atheist. Therefore, given limited poll options, some may use other terms to describe their identity. Some politically motivated organizations that report or gather population statistics may, intentionally or unintentionally, misrepresent atheists. Survey designs may bias results by the wording of questions and the available response options. Statistics are generally collected on the assumption that religion is a categorical variable. Instruments have been designed to measure attitudes toward religion, including one that was used by
L. L. Thurstone. This may be a particularly important consideration among people who have neutral attitudes, as it is more likely that prevailing social norms will influence the responses of such people on survey questions that effectively force respondents to categorize themselves either as belonging to a particular religion or as belonging to no religion. A negative perception of atheists and pressure from family and peers may also cause some atheists to disassociate themselves from atheism. Misunderstanding of the term may also be a reason some label themselves differently.
For example, a Canadian poll released 12 September 2011 sampled 1,129 Canadian adults and collected data on the numbers of declared atheists. These numbers conflicted with the latest
Canadian census data that presupposed that a religious affiliation predisposed a belief in a deity and was based on a poorly worded question. A quote from the study:
The data also revealed some interesting facts about Canadians' beliefs:

Even when people directly claim not to believe in a deity, they still do not self-identify as "atheist". For instance, 41% of Norwegians, 48% of the French, and 54% of Czechs claimed not to believe in a deity, but only 10%, 19%, and 20% of those respondents, respectively, self-identified as "atheist".
In the United States, only 5% of the 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".

. The percentages on telepathy and reincarnation were similar to the percentages of "religious people" in the Netherlands. Furthermore, the author of the study notes, "Thus, despite the fact that they claim to be convinced atheists and the majority deny the existence of a personal god, a rather large minority of the Dutch convinced atheists believe in a supernatural power!"
A 2004 survey by the BBC in 10 countries showed the proportion of the population "who don't believe in God" to be close to 17% in the countries surveyed; however, 8% of the respondents specifically stated that they consider themselves to be "atheists". Diversity was observed in that "across the entire sample, almost 30% of all atheists surveyed said they sometimes prayed."

note that it is unlikely that most atheists and agnostics do not believe in the gods based on a careful analysis of philosophical and scientific arguments alone, since science testing scores in societies where atheism or theism is widespread, can be just as poor and such societies can have widespread supernatural beliefs besides gods.
Reviewing psychological studies on atheists, Miguel Farias noted that studies concluding that analytical thinking leads to lower religious belief "do not imply that that atheists are more conscious or reflective of their own beliefs, or that atheism is the outcome of a conscious refutation of previously held religious beliefs" since they too have variant beliefs such as in

of the naturalistic variety.
In terms of apostasy, Farias notes that a greater proportion of people who leave religion do so for motivational rather than rational reasons and the majority of deconversions occur in adolescence and young adulthood when one is emotionally volatile.
Furthermore, Farias notes that atheists are indistinguishable from New Age individuals or Gnostics since there are commonalities such as being individualistic, non-conformist, liberal, and valuing

(discipline or impulse control, and acting on values like "pursuit of truth"). Secular group members tended to be less
agreeable (e.g. more likely to hold unpopular, socially challenging views), as well as more
open minded (e.g. more likely to consider new ideas) than members of religious groups. Luke Galen, a personality researcher, writes "Many previously reported characteristics associated with religiosity are a function not of belief itself, but of strong convictions and group identification."

concerns and posits that this is due to their lack of belief in an afterlife, leading to a focus on what can be fixed here and now. Another study by Caldwell-Harris describes atheists as being capable of experiencing awe, which she states debunks stereotypes of atheists as "cynical and joyless". A 2014 study created six different personality profiles of 'types' of nonbelievers and compared them to Big Five personality traits. In countries which have high levels of atheism such as Scandinavian nations, atheist organizations there generally have very low membership and only those that have links to a political party or offer legalized rituals have some noticeable membership.

In a global study on atheism, sociologist Phil Zuckerman noted that countries with higher levels of atheism also had the highest suicide rates compared to countries with lower levels of atheism. He concludes that correlations does not necessarily indicate causation in either case. A study on depression and suicide suggested that those without a religious affiliation have a higher suicide attempt rates than those with a religious affiliation. A study into mental well-being in religious and non-religious people found that mental well-being for both religious people and non-religious people hinged on the certainty of their belief, and that previous studies had not controlled for the effect of belonging to a group when studying churchgoers. Benjamin Beit-Hallahmi regarded atheists in Western society to be "much more likely to be a man, married, with higher education", and regarded the personality of atheists to be "less authoritarian and suggestible, less
dogmatic, less prejudiced, more tolerant of others, law-abiding, compassionate, conscientious, and well educated. They are of high intelligence, and many are committed to the intellectual and scholarly life". A review of the literature found that being non-religious did not necessarily entail poorer mental health.
Geographic distribution
Though atheists are in the minority in most countries, they are relatively common in Europe, Canada, Australia, New Zealand, East Asia and present communist states. It is difficult to determine actual atheist numbers.
In 1916, 1,000 leading American scientists were randomly chosen from '' American Men of Science'' and 41.8% believed God existed, 41.5% disbelieved, and 16.7% had doubts/did not know. When the study was replicated 80 years later using '' American Men and Women of Science'' in 1996 results were similar, with 39.3% believing God exists, 45.3% disbelieved, and 14.5% had doubts/did not know.[Larson, E.
