Remarks: Because officially Muslim governments (such as Saudi Arabia,[44] Iran,[45] Sudan,[46] Somalia,[47] Afghanistan,[48] Pakistan[49] and Persian Gulf States[50]) that often forcibly suppress other religious beliefs rule a number of traditionally Islamic countries, the figures for these other religious groups could be higher than reported in those nations. While conversion to Islam is among its most supported tenets, conversion from Islam to another religion is considered to be the sin of apostasy. According to the Hadith[51] and in some countries it is subject to the penalty of death.[52] See Freedom of religion by country and Apostasy in Islam.

  19.  Northern Mariana Islands 16% (Mahayana – 10% practicing)
  20.  North Korea 14% (Mahayana – 2% practicing)
Remarks: East Asian Buddhism is the mixture of Mahayana Buddhism, with Taoism and Confucianism. Because officially Communist governments that often forcibly suppressed religious expressions still rule a number of traditionally Buddhist countries, and because Buddhists often practice other traditional East Asian religions, the figures could be much higher in these regions. Mahayana Buddhism in Far East Asian countries has a very wide meaning. That is why in such countries as China, Vietnam, North and South Korea, Taiwan, Hong Kong, and Singapore, the three religions of Buddhism, Taoism and Confucianism are often all considered at once. This is referred to as a "Triple religion", with Gautama Buddha in the center, Laozi in the left, and Confucius in the right.
In some regions, such as Japan, belief systems vary with differing emphasis on Shintoism, as well as Ancestor Worship. Additionally, as Buddhism has harmonized with many Asian cultures, it is often regarded as a cultural background or philosophy rather than a formal religion. As such, the Buddhist population is difficult to gauge exactly, but is often nominal. The lesser percentage given is a number of Buddhists who have taken the formal step of going for refuge. And the wider percentage given are informal/nominal adherents of combined Buddhism with its related religions and those who subscribe to Buddhism and its philosophies in principle but stop short of any ceremonial or formal practice.[53][54][55][56][57][58][59][60][61] See Buddhism by country and Irreligion.

Remarks: Ranked by mean estimate which is in brackets. Irreligious includes agnostic, atheist, secular believer, and people having no formal religious adherence. It does not necessarily mean that members of this group don′t belong to any religion. Some religions have harmonized with local cultures and can be seen as a cultural background rather than a formal religion. Additionally, the practice of officially associating a family or household with a religious institute while not formally practicing the affiliated religion is common in many countries. Thus, over half of this group is theistic and/or influenced by religious principles, but nonreligious/non-practicing and not true atheists or agnostics.[3] See Spiritual but not religious.

Sikhism

Countries with the greatest proportion of Sikhs:
  1.  India 1.9%
  2.  United Kingdom 1.2%[114][115]
  3.  Canada 0.9%[116]
  4.  Malaysia 0.5%[117]

  9.  Australia 0.1%[124][125]
  10.  Italy 0.1%[126]
The Sikh homeland is the Punjab state, in India, where today Sikhs make up approximately 61% of the population. This is the only place where Sikhs are in the majority. Sikhs have emigrated to countries all over the world – especially to English-speaking and East Asian nations. In doing so they have retained, to an unusually high degree, their distinctive cultural and religious identity. Sikhs are not ubiquitous worldwide in the way that adherents of larger world religions are, and they remain primarily an ethnic religion. But they can be found in many international cities and have become an especially strong religious presence in the United Kingdom and Canada.[127]

Taoists/Confucianists/Chinese traditional religionists

As a spiritual practice, Taoism has made fewer inroads in the West than Buddhism and Hinduism. Despite the popularity of its great classics the I Ching and the Tao Te Ching, the specific practices of Taoism have not been promulgated in America with much success;[128] these religions are not ubiquitous worldwide in the way that adherents of bigger world religions are, and they remain primarily an ethnic religion. Nonetheless, Taoist ideas and symbols such as Taijitu have become popular throughout the world through Tai Chi Chuan, Qigong, and various martial arts.[129]
