Irreligion (adjective form: non-religious or irreligious) is the absence, indifference to, or rejection of religion.  According to the Pew Research Center's 2012 global study of 230 countries and territories, 16% of the world's population is not affiliated with a religion, while 84% are affiliated. 
Irreligion may include some forms of theism, depending on the religious context it is defined against; for example, in 18th-century Europe, the epitome of irreligion was deism,  while in contemporary East Asia the shared term meaning "irreligion" or "no religion" (無宗教 / 无宗教, Chinese pron. wú zōngjiào, Japanese pron. mu shūkyō, Korean pron. mu jonggyo), with which the majority of East Asian populations identify themselves, implies non-membership in one of the institutional religions (such as East Asian Buddhism) and not necessarily non-belief in traditional folk religions collectively represented by Chinese Shendao, Japanese Shinto and Korean Shindo (神道, meaning " dao (ways) of gods"). 
According to cross-cultural studies, since religion and fertility are positively related while irreligion and fertility are negatively related, non-religious identity is expected to decline as a proportion of the global population throughout the 21st century.  By 2060, according to their projections, the number of unaffiliated will increase by over 35 million, but the percentage will decrease to 13% because the total population will grow faster.  
The term irreligion is a combination of the noun religion and the prefix ir-, 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. 
- Secular humanism embraces human reason, ethics, social justice, and philosophical naturalism while specifically rejecting religious dogma, supernaturalism, pseudoscience, and superstition as the bases of morality and decision making. Secular humanism posits that human beings are capable of being ethical and moral without religion or a god.
- Freethought holds that positions regarding truth should be formed on the basis of logic, reason, and empiricism, rather than authority, tradition, revelation, or other dogma. In particular, freethought is strongly tied with rejection of traditional religious belief.
- " Spiritual but not religious" rejects organized religion as the sole or most valuable means of furthering spiritual growth. In contrast to religion, spirituality has often been associated with the interior life of the individual.
- Theological noncognitivism is the argument that religious language – specifically, words such as God – are not cognitively meaningful. It is sometimes considered as synonymous with ignosticism.
- Naturalism is the idea or belief that only natural (as opposed to supernatural or spiritual) laws and forces operate in the universe.  Adherents of naturalism assert that natural laws are the rules that govern the structure and behavior of the natural universe and that the changing universe at every stage is a product of these laws.
- Secularism refers to the a political conviction that the church and the state should be separate entities. Secularists, who can be religious or irreligious, believe that organised religion should not happen in public places like schools. 
- Atheism is the rejection of belief that any deities exist or, in a narrower sense, atheism is specifically the position that there are no deities. There are ranges from Negative and positive atheism. 
- Agnosticism is the view that the existence of God, of the divine or the supernatural is unknown or unknowable. 
- Agnostic atheism is a philosophical position that encompasses both atheism and agnosticism. Agnostic atheists are atheistic because they do not hold a belief in the existence of any deity and agnostic because they claim that the existence of a deity is either unknowable in principle or currently unknown in fact. 
- Deism is the philosophical position that rejects revelation as a source of religious knowledge and asserts that reason and observation of the natural world are sufficient to establish the existence of a Supreme Being or creator of the universe.   
- Apatheism is the attitude of apathy towards the existence or non-existence of god(s).  
- Antireligion is opposition to religion of any kind. It can describe opposition to organized religion, religious practices, religious institutions, or specific forms of supernatural worship or practice, whether organized or not.
In 1993, the UN's 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."  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.  
A noted exception to ambiguity, explicitly allowing non-religion, is Article 36 of the Constitution of the People's Republic of China (as adopted in 1982), which states that "No state organ, public organization or individual may compel citizens to believe in, or not to believe in, any religion; nor may they discriminate against citizens who believe in, or do not believe in, any religion."  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." 
Although 11 countries listed below have nonreligious majorities, it does not mean that the majority of the populations of these countries don't belong to any religious group. For example, 58% of the Swedish population belongs to the Lutheran Christian Church,  while 59% of Albanians declare themselves as religious.[ citation needed] Also, though Scandinavian countries have among the highest measures of nonreligiosity and even atheism in Europe, 47% of atheists who live in those countries are still members of the national churches. 
A Pew 2015 global projection study for religion and nonreligion, projects that between 2010 and 2050, there will be some initial increases of the unaffiliated followed by a decline by 2050 due to lower global fertility rates among this demographic.  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. 
According to Pew Research Center's 2012 global study of 230 countries and territories, 16% of the world's population is not affiliated with a religion, while 84% are affiliated.  A 2012 Worldwide Independent Network/Gallup International Association report on a poll from 57 countries reported that 59% of the world's population identified as religious person, 23% as not religious person, 13% as "convinced atheists", and also a 9% decrease in identification as "religious" when compared to the 2005 average from 39 countries.  Their follow-up report, based on a poll in 2015, found that 63% of the globe identified as religious person, 22% as not religious person, and 11% as "convinced atheists".  Their 2017 report found that 62% of the globe identified as religious person, 25% as not religious person, and 9% as "convinced atheists".  However, researchers have advised caution with the WIN/Gallup International figures since other surveys which use the same wording, have conducted many waves for decades, and have a bigger sample size, such as World Values Survey; have consistently reached lower figures for the number of atheists worldwide. 
Being nonreligious is not necessarily equivalent to being an atheist or agnostic. Pew Research Center's global study from 2012 noted that many of the nonreligious actually have some religious beliefs. For example, they observed that "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."  Out of the global nonreligious population, 76% reside in Asia and the Pacific, while the remainder reside in Europe (12%), North America (5%), Latin America and the Caribbean (4%), sub-Saharan Africa (2%) and the Middle East and North Africa (less than 1%). 
The term "nones" is sometimes used in the U.S. to refer to those who are unaffiliated with any organized religion. This use derives from surveys of religious affiliation, in which "None" (or "None of the above") is typically the last choice. Since this status refers to lack of organizational affiliation rather than lack of personal belief, it is a more specific concept than irreligion. A 2015 Gallup poll concluded that in the U.S. "nones" were the only "religious" group that was growing as a percentage of the population.

無宗教 mushūkyō, "no religion", in Japanese language and mindset identifies those people who do not belong to organised religion. To the Japanese, the term "religion" or "faith" means organised religions on the model of Christianity, that is a religion with specific doctrines and requirement for church membership. So, when asked "what is their religion", most of the Japanese answer that they "do not belong to any religion". According to NHK studies, those Japanese who identify with mushūkyō and therefore do not belong to any organised religion, actually take part in the folk ritual dimension of Shinto. Ama Toshimaru in Nihonjin wa naze mushukyo na no ka ("Why are the Japanese non-religious?") of 1996, explains that people who do not belong to organised religions but regularly pray and make offerings to ancestors and protective deities at private altars or Shinto shrines will identify themselves as mushukyo. Ama designates "natural religion" what NHK studies define as "folk religion", and other scholars have named "Nipponism" (Nipponkyō) or "common religion".

In general, deism refers to what can be called natural religion, the acceptance of a certain body of religious knowledge that is inborn in every person or that can be acquired by the use of reason and the rejection of religious knowledge when it is acquired through either revelation or the teaching of any church.

Deism is a rationalistic, critical approach to theism with an emphasis on natural theology. The deists attempted to reduce religion to what they regarded as its most foundational, rationally justifiable elements. Deism is not, strictly speaking, the teaching that God wound up the world like a watch and let it run on its own, though that teaching was embraced by some within the movement.
