Irreligion |
---|
Irreligion is the absence or rejection of religious beliefs or practices. It encompasses a wide range of viewpoints drawn from various philosophical and intellectual perspectives, including atheism, agnosticism, religious skepticism, rationalism, secularism, and non-religious spirituality. These perspectives can vary, with individuals who identify as irreligious holding diverse beliefs about religion and its role in their lives. [1]
Relatively little scholarly research was published on non-belief until 15 years ago. [2]
Over the past several decades, the number of secular persons has increased, with a rapid rise, early 21st century, in many countries. [3] [4] : 4 [1] [5] : 112 [6] In virtually every high-income country and many poor countries, religion has declined. [5] : 112 However, irreligious people might decline as a share of the world population because of faster population growth in highly religious countries. [1] [7] Pew Research Center (Pew) expects it to probably decrease, at least for a time, from 16.4% to 13.2% by 2050 for this reason. [7] It's also possible that many countries are gradually becoming more secular, generation by generation. [7] Younger generations tend to be less religious than their elders. [7] [8] [9] : 5 They might become more religious as they age, but still be less religious than previous generations if their countries become more affluent and stable. [9] : 13 Measures of religion are complex and not linear as is shown from decades of research on belief, belonging, and behavior. [10] [ page needed ] Consistency among an individual's religious beliefs and attitudes is rare as is shown from decades of anthropological, sociological, and psychological research. [11] [12]
Estimating the number of irreligious people in the world is difficult. [13] [1] Those who do not affiliate with a religion are diverse. In many countries censuses and demographic surveys do not separate atheists, agnostics and those responding "nothing in particular" as distinct populations, obscuring significant differences that may exist between them. [14] : 60 People can feel reasonable anxieties about giving a politically ‘wrong’ answer – in either direction. [13] Measurement of irreligiosity requires a high degree of cultural sensitivity, especially outside the West, where the concepts of "religion" or "the secular" are not always rooted in local culture or even exist. [4] : 13-15,31-34 Also, there's considerable prevalence of atheism and agnosticism in ancient Asian texts. [15] Atheistic traditions have played a significant part in those cultures for millennia. [15] "Cultural religion" must be taken into account: non-religious people can be found in religious categories, especially where religion has very deep-seated religious roots in a culture. [14] : 59 Many of the religiously unaffiliated have some religious beliefs. [16] [17] : 24 Also, some of them engage in certain kinds of religious practices. [16] [17] : 24 In 2016, Zuckerman, Galen and Pasquale estimated there were 400 million nonreligious or nontheistic people. [18] A 2022 Gallup International Association (GIA) survey, done in 61 countries, reported that 62% of respondents said they are religious, one in four that they aren't, 10% that they're atheists and the rest are not sure. [19] In 2016, it found similar results (62%, 25%, 9% and 5%), also in 2014. [19] [20] : 1 : 3 People in the European Union, East Asia and Oceania were the least religious. [19] In 2010, according to Pew, the religiously unaffiliated numbered more than 1.1 billion, about one-in-six people (16.3% of an estimated 6.9 billion). [21] [16] [17] : 24 : 25 76% of them resided in the 60 countries of Asia-Pacific. [16] [17] : 25 : 46 : 66 China, an atheist state and the world's most populous country, alone held the majority (62.2% or about 700 million). [22] [1] [16] [17] : 25 : 46 : 66 Several smaller countries eclipse China's percent of residents who are irreligious. [22] Shares were relatively similar in three of the six regions: Asia-Pacific (21.2% of more than 4 billion), Europe (18.2% of more than 742 thousands) and North America (17.1% of more than 344 thousands). [16] [17] : 25
irreligion is either a borrowing from French or from Latin. [23] The term irreligion is a combination of the noun religion and the ir- form of the prefix in-, signifying "not" (similar to irrelevant). It was first attested in French as irréligion in 1527, then in English as irreligion in 1598. It was borrowed into Dutch as irreligie in the 17th century, though it is not certain from which language. [24]
According to the encyclopedia Britannica , the term irreligion is frequently characterized differently depending on context. [1] Sometimes, surveys of religious belief use lack of identification with a religion as a marker of irreligion. [1] This can be misleading: in some cases a person may identify with a religious cultural institution but not hold the doctrines of that institution or take part in its religious practice. [1]
Some scholars define irreligion as the active rejection of religion, as opposed to the mere absence of religion. [1] The Encyclopedia of Religion and Society defines it as: "Active rejection of religion in general or any of its more specific organized forms. It is thus distinct from the secular, which simply refers to the absence of religion. [...] In contemporary usage, it is increasingly employed as a synonym for unbelief [...]" [25] [26]
The Oxford English Dictionary has two definitions, one of which is labelled obsolete (first published in 1900). [23] It is want of religion; hostility to or disregard of religious principles; irreligious conduct. [23]
The Merriam Webster Dictionary defines it as "the quality or state of being irreligious" and "irreligious" as "neglectful of religion: lacking religious emotions, doctrines, or practices", also "indicating lack of religion". [27]
In 1993, the United Nations Human Rights Committee declared that article 18 of the International Covenant on Civil and Political Rights "protects theistic, non-theistic and atheistic beliefs, as well as the right not to profess any religion or belief." [32] The committee further stated that "the freedom to have or to adopt a religion or belief necessarily entails the freedom to choose a religion or belief, including the right to replace one's current religion or belief with another or to adopt atheistic views." Signatories to the convention are barred from "the use of threat of physical force or penal sanctions to compel believers or non-believers" to recant their beliefs or convert. [33] [34]
Most democracies protect the freedom of religion or belief, and it is largely implied in respective legal systems that those who do not believe or observe any religion are allowed freedom of thought.
A noted exception to ambiguity, explicitly allowing non-religion, is Article 36 of the Constitution of China (as adopted in 1982), which states that "No state organ, public organization or individual may compel citizens to believe in, or not believe in, any religion; nor may they discriminate against citizens who believe in, or do not believe in, any religion." [35] Article 46 of China's 1978 Constitution was even more explicit, stating that "Citizens enjoy freedom to believe in religion and freedom not to believe in religion and to propagate atheism." [36]
Women in the labor force are more like men in religiosity. [38] When they are out of it, they tend to be more religious. [38]
In many countries censuses and demographic surveys do not separate atheists, agnostics and those responding "nothing in particular" as distinct populations. [14] : 60
Eleven countries have nonreligious majorities. In 2020, the countries with the highest percentage of "Non-Religious" ("Term encompassing both (a) agnostics; and (b) atheists") were North Korea, the Czech Republic and Estonia. [39] According to the 2018 Chinese General Social Survey, the country had the largest count of unaffiliated people: about one billion adults. [40] Some boadly religious practices continue to play a significant role in the lives of a substantial shares of the Chinese population. [40]
Determining objective irreligion, as part of societal or individual levels of secularity and religiosity, requires a high degree of cultural sensitivity from researchers. This is especially so outside the Western world, where the concepts of "religious" and "secular" are not necessarily rooted in local culture or even exist. [4] : 13-15,31-34 "Cultural religion" is a vivid reality. [14] : 59 It must be taken into account when trying to ascertain the numeric strength of atheism and agnosticism in a country. [14] : 59 It is generally not considered more important than self-identification measures. [14] : 59 Non-religious people can be found in religious categories. [14] : 59 This is especially the case where religion has very deep-seated religious roots in a culture, such as with Christianity in Europe, Islam in the Middle East, Hinduism in India, and Buddhism in South-east Asia. [14] : 59 For instance, Scandinavian countries have among the highest measures of nonreligiosity and even atheism in Europe. For example, 58% of the Swedish population identify with the Church of Sweden. [41] Yet, 47% of atheists who live in those countries are still formally members of the national churches. [42] [ pages needed ] Many East Asians identify as "without religion" (wú zōngjiào in Chinese, mu shūkyō in Japanese, mu jong-gyo in Korean), but "religion" in that context refers only to Buddhism or Christianity. Most of the people "without religion" practice Shinto and other folk religions. In the Muslim world, those who claim to be "not religious" mostly imply not strictly observing Islam, and in Israel, being "secular" means not strictly observing Orthodox Judaism. Vice versa, many American Jews share the worldviews of nonreligious people though affiliated with a Jewish denomination, and in Russia, growing identification with Eastern Orthodoxy is mainly motivated by cultural and nationalist considerations, without much concrete belief. [43]
In 2016, Zuckerman, Galen and Pasquale estimated there were 400 million nonreligious or nontheistic people. [18] In their 2013 essay, Ariela Keysar and Juhem Navarro-Rivera estimated there were about 450 to 500 million nonbelievers, including both "positive" and "negative" atheists, or approximately 7% of the world population. [44] These estimates come from the International Social Survey Programme 2008 survey in which 40 countries took part. [45] In 2010, the religiously unaffiliated numbered more than 1.1 billion (around 1,126,500,000 persons), about one-in-six people (16.3% of an estimated 6,9 billion world population), according to Pew Research Center. [21] [16] [17] : 24 : 25 In Pew reports, "unaffiliated" are atheists, agnostics, and people who checked "nothing in particular". [14] : 60 76% of them resided in one of the six regions: Asia-Pacific. [16] [17] : 25 A 2012 WIN/Gallup International report on a poll from 57 countries reported that 59% of the world's population identified as a religious person, 23% as not a religious person, 13% as "convinced atheists", and also a 9% decrease in identification as "religious" when compared to the 2005 average from 39 countries. [46] A 2015 WIN/Gallup International poll found that 63% of the globe identified as a religious person, 22% as not a religious person, and 11% as "convinced atheists". [47] Their 2016 survey found that 62% of the globe identified as a religious person, less than 25% as not a religious person, 9% others as "convinced atheists" and 5% others "Do not know/no response". [20] Keysar and Navarro-Rivera advised caution with these figures since other surveys have consistently reached lower figures for the number of atheists worldwide. [48] : 553 : 554
Inverse association between intelligence and religiosity, and the inverse correlation between intelligence and fertility might lead to a decline in non-religious identity (contra-secularization hypothesis) in the foreseeable future. [49] [50] : 2 In 2007, sociologist Phil Zuckerman's global studies on atheism 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. [51] A Pew 2015 global projection study for religion and nonreligion, projected that between 2010 and 2050, there will be some initial increases of the unaffiliated followed by a decline by 2050. [52] Some theorists think religion will fade away but Pew reveals a more complicated picture. [7] Pew predicts the unaffiliated share of the world population will decrease, at least for a while, from 16.4% to 13.2% by 2050. [53] [7] Pew states that religious areas are experiencing the fastest growth because of higher fertility and younger populations. [7] [54] By 2060, Pew says the number of unaffiliated will increase by over 35 million, but the overall population-percentage will decrease to 13% because the total population will grow faster. [55] [56] This would be mostly because of relatively old age and low fertility rates in less religious societies such as East Asia, particularly China and Japan, but also Western Europe. [53] [1] By 2019, 43 out of 49 countries studied continued to become less religious. [5] : 110 [6]
Being nonreligious is not necessarily equivalent to being an atheist or agnostic. Many of the nonreligious have some religious beliefs. [16] [17] : 24 Also, some of the unaffiliated engage in certain kinds of religious practices. [16] [17] : 24 For example, "belief in God or a higher power is shared by 7% of Chinese unaffiliated adults, 30% of French unaffiliated adults and 68% of unaffiliated U.S. adults. [16] [17] : 24 Being unaffiliated with a religion on polls does not automatically mean objectively nonreligious since there are, for example, unaffiliated people who fall under religious measures, just as some unbelievers may still attend a church or other place of worship. [14] [ pages needed ] Out of the global nonreligious population, 76.2% reside in Asia-Pacific, while the remainder reside in Europe (12%), North America (5.2%), Latin America and the Caribbean (4%), sub-Saharan Africa (2.4%) and the Middle East and North Africa (0.2%). [16] [17] : 24
The Pew Research Centre in the table below reflects "religiously unaffiliated" in 2010 which "include atheists, agnostics, and people who do not identify with any particular religion in surveys".
The Zuckerman data on the table below only reflect the number of people who have an absence of belief in a deity only (atheists, agnostics). These do not include the broader number of people who do not identify with a particular religion, such as deists, pantheists, and spiritual but not religious people.

Since 2007, there has been a surprising remarkably sharp trend away from religion. [6] [5] From about 2007 to 2019, 43 out of 49 countries studied became less religious. [6] Past influential thinkers from Karl Marx to Max Weber to Émile Durkheim thought that the spread of scientific knowledge would dispel religion throughout the world. [5] : 112 Industrialization also didn't cause religion to disappear. [5] : 110 Political scientists Ronald Inglehart and Pippa Norris argue faith is "more emotional than cognitive", and both advance an alternative thesis termed "existential security." They postulate that rather than knowledge or ignorance of scientific learning, it is the weakness or vulnerability of a society that determines religiosity. They claim that increased poverty and chaos make religious values more important to a society, while wealth and security diminish its role. As need for religious support diminishes, there is less willingness to "accept its constraints, including keeping women in the kitchen and gay people in the closet". [59]
Rates of people identifying as non-religious began rising in most societies at least as early as the turn of the 20th century. [60] In 1968, sociologist Glenn M. Vernon wrote that US census respondents who identified as "no religion" were insufficiently defined because they were defined in terms of a negative. He contrasted the label with the term "independent" for political affiliation, which still includes people who participate in civic activities. He suggested this difficulty in definition was partially due to the dilemma of defining religious activity beyond membership, attendance, or other identification with a formal religious group. [60] During the 1970s, social scientists still tended to describe irreligion from a perspective that considered religion as normative for humans. Irreligion was described in terms of hostility, reactivity, or indifference toward religion, and or as developing from radical theologies. [61]

In a study of religious trends in 49 countries (they contained 60 percent of the world’s population) from 1981 to 2007, Inglehart and Norris found an overall, but not universal, increase in religiosity. [5] : 110 Respondents in 33 of 49 countries rated themselves higher on a scale from one to ten when asked how important God was in their lives. This increase occurred in most former communist and developing countries. Most high-income countries became less religious. [5] : 112 A sharp reversal of the global trend occurred from 2007 to 2019, when 43 out of 49 countries studied became less religious. This reversal appeared across most of the world. [5] The decline in belief was not confined to high-income countries and appeared across most of the world. [6] In virtually every high-income country, religion has continued to decline. [5] : 112 At the same time, many poor countries, together with most of the former communist states, have also become less religious. [5] : 112 From 2007 to 2019, only five countries became more religious, whereas the vast majority of the countries studied moved in the opposite direction. [5] : 112 India is the most important exception to the general pattern of declining religiosity. [5] : 112 The United States was a dramatic example of declining religiosity –with the mean rating of importance of religion dropping from 8.2 to 4.6 –while India was a major exception. Research in 1989 recorded disparities in religious adherence for different faith groups, with people from Christian and tribal traditions leaving religion at a greater rate than those from Muslim, Hindu, or Buddhist faiths. [62]
Inglehart and Norris speculate that the decline in religiosity comes from a decline in the social need for traditional gender and sexual norms, ("virtually all world religions instilled" pro-fertility norms such as "producing as many children as possible and discouraged divorce, abortion, homosexuality, contraception, and any sexual behavior not linked to reproduction" in their adherents for centuries) as life expectancy rose and infant mortality dropped. They also argue that the idea that religion was necessary to prevent a collapse of social cohesion and public morality was belied by lower levels of corruption and murder in less religious countries. They argue that both of these trends are based on the theory that as societies develop, survival becomes more secure: starvation, once pervasive, becomes uncommon; life expectancy increases; murder and other forms of violence diminish. As this level of security rises, there is less social/economic need for the high birthrates that religion encourages and less emotional need for the comfort of religious belief [5] Change in acceptance of "divorce, abortion, and homosexuality" has been measured by the World Values Survey and shown to have grown throughout the world outside of Muslim-majority countries. [5]
In sociology, secularization is a multilayered concept that generally denotes "a transition from a religious to a more worldly level." There are many types of secularization and most do not lead to atheism, irreligion, nor are they automatically antithetical to religion. Secularization has different connotations such as implying differentiation of secular from religious domains, the marginalization of religion in those domains, or it may also entail the transformation of religion as a result of its recharacterization.
The study of religiosity and intelligence explores the link between religiosity and intelligence or educational level. Religiosity and intelligence are both complex topics that include diverse variables, and the interactions among those variables are not always well understood. For instance, intelligence is often defined differently by different researchers; also, all scores from intelligence tests are only estimates of intelligence, because one cannot achieve concrete measurements of intelligence due to the concept’s abstract nature. Religiosity is also complex, in that it involves wide variations of interactions of religious beliefs, practices, behaviors, and affiliations, across a diverse array of cultures.
Accurate demographics of atheism are difficult to obtain since conceptions of atheism 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 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".
Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there are no deities. Atheism is contrasted with theism, which is the belief that at least one deity exists.
In the United States, between 4% and 15% of citizens demonstrated nonreligious attitudes and naturalistic worldviews, namely atheists or agnostics. The number of self-identified atheists and agnostics was around 4% each, while many persons formally affiliated with a religion are likewise non-believing.
A 2023 poll by the Pew Research Center found that 4% of Americans in the United States self-identified as atheists. This is an increase from 3.1% of Americans in 2014. 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". According to a poll by non-profit PRRI in 2023, 4% of Americans were atheist and 5% were agnostic. 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. According to Gallup, there are variations in their polling results because they ask about God in three different wordings, each with a different result.
Irreligion in Belgium pertains to citizens of Belgium that are atheist, agnostic, or otherwise unaffiliated with any religion. Irreligion is the second most common religious stance in Belgium, following Catholicism.
Irreligion in Estonia pertains to atheism, agnosticism, and secularism of the people and institutions of Estonia. Irreligion is prominent in Estonia, where a majority of citizens are unaffiliated with any religion. Estonian irreligion dates back to the 19th century, when Estonian nationalists and intellectuals deemed Christianity a foreign religion in opposition to Estonian independence. Irreligion in Estonia was later accelerated by the Soviet occupation of the Baltic states, in which state atheism was enforced. By some metrics, Estonia is the most irreligious country in the world.
Irreligion is common in Sweden, and Sweden is one of the most secular nations in the world. The majority of Swedish citizens are members of the Church of Sweden, but very few are practicing members. Sweden has legally been a secular state since 2000 when the Church of Sweden was separated from the state.
Irreligion in Ireland pertains to the population of Ireland that are atheist, agnostic, or otherwise unaffiliated with any religion. The 2022 census recorded that 14% of the population was irreligious; the second largest category after Roman Catholicism. The population was traditionally devoutly Catholic throughout much of Ireland's modern history, with a peak of 94.9% identifying as Catholic in the 1961 census. This percentage has declined to 69% in the 2022 census, the lowest recorded. Conversely, those with no religion made up less than 0.1% of the population in 1961; the proportion grew slowly until the 1991 census where it began to rapidly increase to its current share of 14% of the population in 2022.
According to public opinion polls, irreligion in Uruguay ranges from 30 to 40 to over 47 percent of the population. Uruguay has been the least-religious country in South America due to nineteenth-century political events influenced by positivism, secularism, and other beliefs held by intellectual Europeans. The resistance of the indigenous population to evangelization, which prevented the establishment of religion during the colonial era, has also been influential. According to Nestor DaCosta (2003), irreligion has historically been a feature of Uruguayan identity.
The relationship between the level of religiosity and the level of education has been studied since the second half of the 20th century.
China has the world's largest irreligious population, and the Chinese government and the ruling Chinese Communist Party have conducted antireligious campaigns throughout their rule. Religious freedom is protected under the Chinese constitution. Among the general Chinese population, there are a wide variety of religious practices. The Chinese government's attitude to religion is one of skepticism and non-promotion.
Irreligion in Africa, encompassing also atheism in Africa as well as agnosticism, secular humanism and general secularism, has been estimated at over tens of millions in various polls. While the predominant religions in Africa are Islam and Christianity, many groups and individuals still practice their traditional beliefs. Despite this the irreligious population is notable, especially in South Africa where 15.1% of the population describe themselves as irreligious and in Botswana, where 20% of the population describes themselves as non-religious.
Philip Joseph Zuckerman is a sociologist and professor of sociology and secular studies at Pitzer College in Claremont, California. He specializes in the sociology of substantial secularity and is the author of eight books, including Beyond Doubt: The Secularization of Society (2023) What It Means to Be Moral: Why Religion Is Not Necessary for Living an Ethical Life (2019).
Irreligion in Latin America refers to various types of irreligion, including atheism, agnosticism, deism, secular humanism, secularism and non-religious. According to a Pew Research Center survey from 2014, 8% of the population is not affiliated with a religion. According to Latinobarómetro, the share of irreligious people in Latin America quadrupled between 1996 and 2020, from 4% to 16%.
Irreligion in Turkey refers to the extent of the lack, rejection of, or indifference towards religion in the Republic of Turkey. Based on surveys, Islam is the predominant religion and irreligious people form a minority in Turkey. Precise estimates of the share of deists, atheists, agnostics, and other unaffiliated people in the population vary, though in survey averages they constitute a larger percentage than Christians and Jews in the country.
Irreligion in Italy includes all citizens of Italy that are atheist, agnostic, or otherwise irreligious. Approximately 12% of Italians are irreligious, and no affiliation is the second most common religious demographic in Italy after Christianity. Freedom of religion in Italy was guaranteed by the Constitution of Italy following its enactment in 1948. Until then, the Catholic Church was the official state church of Italy.
In sociology, desecularization is a resurgence or growth of religion after a period of secularization. The theory of desecularization is a reaction to the theory known as the secularization thesis, which posits a gradual decline in the importance of religion and of religious belief itself, as a universal feature of modern society. The term desecularization was coined by Peter L. Berger, a former proponent of the secularization thesis, in his 1999 book The Desecularization of the World.
