China is officially an atheist state that recognises exactly five religions: Buddhism, Taoism, Islam, Catholicism and Protestantism. The largest form of religious practice in the country is none of them. Chinese folk religion — ancestor veneration, local deities, temple festivals — involves several hundred million people and has no official status at all, which is why published figures for religion in China vary more wildly than for any other country.
The Five Religions the State Recognises
Religious activity in China is legal only through state-sanctioned bodies, one for each recognised faith: the Buddhist Association of China, the Chinese Taoist Association, the Islamic Association of China, the Chinese Patriotic Catholic Association, and the Three-Self Patriotic Movement together with the China Christian Council for Protestants.
Article 36 of the constitution guarantees freedom of religious belief and protects "normal religious activities" — a qualifier doing considerable work, since what counts as normal is decided administratively. The Regulations on Religious Affairs, substantially tightened in a 2018 revision, require venues to register, restrict religious education of minors, and place religious affairs under the United Front Work Department.
Communist Party members, who number close to 100 million, are required to be atheists. This alone removes a substantial slice of the adult population from any religious count, at least officially.
Folk Religion Is the Largest Practice and Counts as Nothing
What most Chinese people actually do is not on the list. Burning incense at a local temple, making offerings at a family grave during Qingming, consulting a fortune teller, honouring the Kitchen God, venerating Mazu on the southern coast — these are widespread, ancient and organised around no institution the state registers.
Estimates of participation run from several hundred million to as much as three-quarters of the population, depending entirely on whether the surveyor counts practices or professed identity. Ask people what religion they belong to and most say none; ask whether they visited a grave at Qingming and the answer changes.
Officially, much of this is classified as folk custom rather than religion, which suits everyone: it keeps the practice legal without requiring registration, and it keeps the official religious population low.
Taoism Is the Only One That Started Here
Taoism is China's indigenous organised religion, drawing on the Daodejing attributed to Laozi and taking institutional form with the Way of the Celestial Masters, conventionally dated to 142 CE. It absorbed a great deal of existing folk practice, which is part of why the line between Taoism and folk religion is blurry in practice.
Its major sites remain active: Wudang Mountain in Hubei, the birthplace of much Taoist martial tradition, and the five sacred mountains, of which Tai Shan in Shandong has been climbed by pilgrims and emperors for over two thousand years.
The state-recognised Taoist clergy number in the tens of thousands, a small figure that badly understates the tradition's reach, since most Taoist-influenced practice happens outside any temple registry.
Buddhism Came Along the Silk Road
Buddhism arrived from India via the Silk Road around the first century CE and became, over the following millennium, the most institutionally powerful religion in Chinese history — powerful enough that emperors periodically suppressed it, most severely in 845 CE when tens of thousands of monasteries were closed.
It is now the largest of the five recognised religions, with estimates around 185 to 250 million adherents depending on the definition, and roughly 33,000 temples. Chan Buddhism, which became Zen in Japan, developed here; the Shaolin Monastery in Henan is its most famous institution.
Tibetan Buddhism is a distinct case with distinct politics. It is practised across Tibet, Qinghai, Sichuan and Inner Mongolia, and its leadership is directly contested: the 14th Dalai Lama has lived in exile in India since 1959, and Beijing asserts the right to approve reincarnations, a claim formalised in 2007 regulations.
The Two Churches, Twice Over
Christianity in China exists in registered and unregistered forms simultaneously, and this doubling is the central fact about it.
Protestants worship either in Three-Self churches, which are registered and supervised, or in unregistered "house churches" that operate in a legal grey zone and have at times been tolerated and at times demolished. Estimates of the total Protestant population range from around 40 million to over 60 million, and the uncertainty is almost entirely about how many people are in unregistered congregations.
Catholicism was split by the question of who appoints bishops. The Chinese Patriotic Catholic Association appointed its own; an "underground" church loyal to Rome refused to recognise them. A provisional agreement between the Vatican and Beijing in 2018, renewed since, established a process giving the Pope a final say over candidates put forward in China — a compromise criticised from both directions, and one that has not ended the split on the ground.
Islam, and Two Very Different Communities
China's Muslim population is usually estimated between 20 and 25 million, and it is not one community. The Hui, roughly half the total, are Chinese-speaking, dispersed across the country and historically integrated — Ningxia is their autonomous region, and the Great Mosque of Xi'an, founded in the eighth century, is built in Chinese architectural style with a pagoda-form minaret.
The Uyghurs are Turkic-speaking, concentrated in Xinjiang, and their situation is entirely different. Since 2017 the region has been subject to mass detention in what the government calls vocational training centres, alongside surveillance, restrictions on religious practice and the demolition or alteration of mosques. UN human rights assessments have described possible crimes against humanity; Beijing rejects the characterisation and describes the measures as counter-terrorism.
The contrast between Hui and Uyghur experience is the clearest illustration that religious policy in China tracks ethnicity and perceived political risk more closely than doctrine.
Confucianism: Religion, Philosophy, or Neither
Confucianism is not among the five recognised religions and its status is genuinely contested. It has temples, rituals, a canon and ancestor veneration at its core, but no deity, no clergy in the usual sense and no conversion.
Chinese officialdom has historically treated it as ethical philosophy, which allowed it to be attacked as feudal ideology during the Cultural Revolution and rehabilitated later as cultural heritage. The Confucius temple at Qufu, his birthplace, is a UNESCO World Heritage site, and the government's Confucius Institutes abroad borrow the name explicitly as culture rather than creed.
Whether it counts as a religion determines whether China is described as historically religious or historically secular — which is a large consequence to hang on a definitional question.
Banned Movements and the Line the State Draws
Alongside the five recognised religions and the tolerated folk practices sits a third category: organisations the state classifies as xiejiao, usually translated as "evil cults" though closer to "heterodox teachings". The designation is administrative rather than theological, and it carries criminal penalties.
Falun Gong is the best-known case. A qigong-based movement that grew rapidly in the 1990s, it was banned in July 1999 after some 10,000 practitioners staged a silent demonstration outside the Zhongnanhai leadership compound — an act of organisation, more than any doctrine, that appears to have triggered the response. A number of Christian-derived new religious movements are on the same list.
The pattern across all three categories is consistent. What determines a religion's standing in China is less what it teaches than whether it can mobilise people outside state structures, which is why an unregistered house church of forty people and a registered temple of four thousand can be treated very differently.
What the Cultural Revolution Destroyed
Between 1966 and 1976, religion of every kind was targeted as one of the Four Olds. Temples, mosques, churches and monasteries were closed, converted to other uses or demolished; clergy were defrocked, imprisoned or sent to labour; scriptures and images were burned. Tibet lost the overwhelming majority of its monasteries.
Religious life resumed after 1978 under the reform era, and much has been physically rebuilt — but the interruption of roughly a generation broke transmission in ways that money cannot restore, particularly for traditions that depended on ordained lineages and oral instruction.
This history is why comparing modern Chinese religious statistics to pre-1949 ones is close to meaningless, and why the sharp growth rates reported for Chinese Christianity in the 1980s and 1990s are partly recovery rather than conversion.
Why the Numbers Cannot Be Pinned Down
Every figure in this article should be read with a wide margin. China's census does not ask about religion. Surveys that do face the problem that admitting to religious belief can carry consequences for employment, party membership and, for some communities, considerably more.
Official figures published by the State Council put total religious believers at around 200 million — under 15% of the population. Independent surveys, counting practice rather than declared affiliation, have produced figures several times higher. Both are measuring something real; they are simply not measuring the same thing.
The honest summary is that China is simultaneously one of the world's least religious countries by self-identification and one of the most religiously active by observance, and no single percentage captures that. For comparison across the region, the count of countries in Asia covers 49 states with almost no shared approach to the question, from India's constitutional pluralism to Indonesia's six recognised faiths.
