Irreligious includes agnostic, atheist, secular people, and those having no formal religious adherence. It does not necessarily mean that those 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. The practice of officially associating a family or household with a religion, 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. See Spiritual but not religious. Hindus Countries with the greatest proportion of Hindus from Hinduism by country in 2010: in 2010 • 81.3% • 79.8% • 48.54% • 27.9% • 25.0% • 24.8% • 22.3% • 18.2% • 15.0% • 12.6% • 12.0% • 9.6% • 8.1% • 6.7% • 6.3% • 5.1% • 3.0% • 2.6% • 2.2% • 2.1% • 1.7% • 1.7% • 1.5% • 1.4% • 1.2% • 0.7% Buddhists Countries with the greatest proportion of Buddhists from Buddhism by country in 2010: in 2010 • 96.9% • 93.2% • 80.1% • 74.7% • 69.3% • 66.0% • 55.1% • 36.2% - 66.7% • 35.1% • 33.2% • 22.9% • 19.8% • 18.2% • 17.3% • 16.4% • 13.2% • 10.6% • 10.3% • 8.6% • 3.1% • 2.8% • 2.7% • 2.5% • 2.0% • 1.6% • 1.5% • 1.2% • 1.1% 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 practice of Taoism has not been promulgated in America with much success. 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, qigong, and various martial arts. • 33.0–80.0% • 30.0% • 28.0% • 13.9% • 8.5% • 2.6% • 0.2–1.0% • 0.01–0.05% • 0.05% In 1999, the Chinese traditional religion had 184,000 believers in Latin America, 250,000 believers in Europe, and 839,000 believers in North America. Ethnic and indigenous religionists Indigenous statistics come from the 2009 U.S. Department of State's International Religious Freedom Act, based on the highest estimate of people identified as indigenous or followers of indigenous religions that have been well-defined. Due to the syncretic nature of these religions, the numbers may not reflect the actual number of practitioners. • 35.6% • 32.9% • 30.9% • 29.5% • 25.0% • 25.0% • 12.0% • 10.5% • 9.0% • 9.0% • 8.5% • 5.0% Sikhs Countries with the greatest proportion of Sikhs: • 2.12% • 1.72% • 1.10% • 0.88% • 0.88% • 0.83% • 0.75% • 0.56% • 0.37% • 0.35% The Sikh homeland is the Punjab state, in India, where Sikhs make up approximately 58% 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. They can be found in many international cities and have become an especially strong religious presence in the United Kingdom and Canada. Sikhism is the fastest growing religion in New Zealand and Australia. Spiritists • 10.3% • 10.2% • 4.8% • 3.6% • 2.7% • 2.2% • 1.9% • 1.5% • 1.4% • 1.3% • 1.1% • 1.0% • 1.0% • 0.9% • 0.7% • 0.5% • 0.5% • 0.4% • 0.2% • 0.2% (ARDA claim) Spiritist estimates come from a single source, which gives a relative indication of the size of the Spiritist communities within each country.
