The U.S. government estimates the total population at 1.4 billion (midyear 2020 estimate). According to the State Council Information Office (SCIO) report Seeking Happiness for People: 70 Years of Progress on Human Rights in China, published in September 2019, there are more than 200 million religious adherents in the country. An SCIO April 2018 white paper on religion in the country states there are approximately 5,500 religious groups.

Local and regional figures for the number of religious followers, including those belonging to the five officially recognized religions, are unclear. Local governments do not release these statistics, and even official religious organizations do not have accurate numbers. The Pew Research Center and other observers say the numbers of adherents of many religious groups often are underreported. The U.S. government estimates that Buddhists comprise 18.2 percent of the country’s total population, Christians 5.1 percent, Muslims 1.8 percent, followers of folk religions 21.9 percent, and atheists or unaffiliated persons 52.2 percent, with Hindus, Jews, and Taoists comprising less than one percent. According to a February 2017 estimate by the U.S.-based NGO Freedom House, there are more than 350 million religious adherents in the country, including 185 to 250 million Chinese Buddhists, 60 to 80 million Protestants, 21 to 23 million Muslims, seven to 20 million Falun Gong practitioners, 12 million Catholics, six to eight million Tibetan Buddhists, and hundreds of millions who follow various folk traditions. According to the Christian advocacy NGO Open Doors USA’s World Watch List 2020 report, there are 97.2 million Christians. According to 2015 data from the World Jewish Congress, the country’s Jewish population is 2,500, concentrated in Beijing, Shanghai, and Kaifeng.

The SCIO’s April 2018 white paper found the number of Protestants to be 38 million. Among these, there are 20 million Protestants affiliated with the Three-Self Patriotic Movement (TSPM), the state-sanctioned umbrella organization for all officially recognized Protestant churches, according to information on TSPM’s website in March 2017. The SCIO report states there are six million Catholics, although media and international NGO estimates suggest there are 10-12 million, approximately half of whom practice in churches not affiliated with the CCPA. Accurate estimates on the numbers of Catholics and Protestants as well as other faiths are difficult to calculate because many adherents practice exclusively at home or in churches that are not state sanctioned.

According to the 2018 SCIO white paper, there are 10 ethnic minority groups totaling more than 20 million persons for whom Islam is the majority religion. Other sources indicate almost all Muslims are Sunni. The two largest Muslim ethnic minorities are Hui and Uyghur, with Hui Muslims concentrated primarily in the Ningxia Hui Autonomous Region and in Qinghai, Gansu, and Yunnan Provinces. The SARA, also referred to as the National Religious Affairs Administration, estimates the Muslim Hui population at 10.6 million. Most Uyghur Muslims are concentrated in the Xinjiang Uyghur Autonomous Region (XUAR) and, along with ethnic Kazakh, Hui, Kyrgyz, and members of other predominantly Muslim ethnic minority groups, number approximately 14.9 million residents, or 60 percent of the total population there.

While there is no reliable government breakdown of the Buddhist population by branch, the vast majority of Buddhists are adherents of Mahayana Buddhism, according to the Pew Research Center.

Prior to the government’s 1999 ban on Falun Gong, the government estimated there were 70 million adherents. Falun Gong sources estimate tens of millions continue to practice privately, and Freedom House estimates there are seven to 20 million practitioners.

Some ethnic minorities follow traditional religions, such as Dongba among the Naxi people in Yunnan Province and Buluotuo among the Zhuang in Guangxi Zhuang Autonomous Region. The central government classifies worship of Mazu, a folk deity with Taoist roots, as an expression of “cultural heritage” rather than religious practice.

The U.S. government estimates the total population at 7.2 million (midyear 2020 estimate). According to SAR government statistics, there are more than one million followers of Taoism and approximately one million followers of Buddhism; 500,000 Protestants; 403,000 Catholics; 300,000 Muslims; 100,000 Hindus; and 12,000 Sikhs. The Catholic Diocese of Hong Kong, which recognizes the Pope and maintains links to the Vatican, reported approximately 620,000 followers (403,000 local residents and 217,000 residents with other nationalities). The Church of Jesus Christ of Latter-day Saints reported it has approximately 25,100 members. According to the World Jewish Congress, there are approximately 2,500 Jews, primarily expatriates. Small communities of Baha’is and Zoroastrians also reside in the SAR. Confucianism is widespread, and in some cases, elements of Confucianism are practiced in conjunction with other belief systems. The Falun Dafa Association estimates there are approximately 500 Falun Gong practitioners.

There are numerous Protestant denominations, including Baptist, Christian and Missionary Alliance, Lutheran, Methodist, Anglican, the Church of Christ in China, Seventh-day Adventist, and Pentecostal.

The U.S. government estimates the total population at 614,000 (midyear 2020 estimate). According to a 2015 estimate by the research group Association of Religion Data Archives, 48.1 percent of the population are folk religionists, 17.3 percent Buddhist, 11 percent Taoist, 4.5 percent Catholic, 2.5 percent other Christian, 1.2 percent other religious groups (including Hindus, Muslims, and Jews), and 15.4 percent nonreligious. The SAR Government Information Bureau 2020 yearbook states the majority of the population practices Buddhism or Chinese folk religions. The yearbook does not provide an estimate for Buddhists, but it states they are numerous and individuals often practice a mixture of Buddhism, Confucianism, and Chinese folk religions. The SAR Government Information Bureau estimates 4.5 percent of the population are Roman Catholics, of whom almost half are foreign domestic workers and other expatriates, and 2.5 percent of the population are Protestants. Protestant denominations include the Anglican, Baptist, Lutheran, Methodist, Pentecostal, and Presbyterian Churches. Evangelical Christian and independent local nondenominational churches, some of which are affiliated with officially recognized mainland churches, are also present. Various reports estimate the Muslim population at 5,000 to 10,000. Smaller religious groups include Baha’is, who estimate their membership at more than 2,000, and Falun Gong practitioners, who estimate their numbers at 20 to 50 persons.

According to official data from the 2018 estimate of the National Bureau of Statistics of China, the total population of the TAR is 3,371,500, of which Tibetans make up approximately 90 percent. Han Chinese make up approximately 8 percent. Other ethnicities comprise the remainder. Some experts, however, believe the number of Han Chinese and other non-Tibetans living there is significantly underreported. Outside the TAR, official census data show Tibetans constitute 24.4 percent of the total population in Qinghai Province, 2.1 percent in Sichuan Province, 1.8 percent in Gansu Province, and 0.3 percent in Yunnan Province, although the percentage of Tibetans is much higher within prefectures and counties of these provinces designated as autonomous for Tibetans.

Most ethnic Tibetans practice Tibetan Buddhism, although a sizeable minority practices Bon, a pre-Buddhist indigenous religion. Small minorities practice Islam, Catholicism, or Protestantism. Some scholars estimate there are as many as 400,000 Bon followers across the Tibetan Plateau, most of whom also follow the Dalai Lama and consider themselves also to be Tibetan Buddhists. Scholars estimate there are up to 5,000 Tibetan Muslims and 700 Tibetan Catholics in the TAR. Other residents of traditionally Tibetan areas include Han Chinese, many of whom practice Buddhism (including Tibetan Buddhism), Taoism, Confucianism, or traditional folk religions, or profess atheism, as well as Hui Muslims and non-Tibetan Catholics and Protestants.

A 2018 report on the XUAR issued by the Department of Population and Employment Statistics of the National Bureau of Statistics estimates the total population was 24.87 million. The report states Uyghurs, along with Kazakh, Hui, Kyrgyz, and members of other predominantly Muslim ethnic minority groups constitute approximately 14.9 million residents in Xinjiang, or 60 percent of the total population. According to the BBC, of these, 12 million are Uyghurs. The largest segment of the remaining population is Han Chinese, with additional groups including Mongols, Tibetans, and others. Most Uyghurs are Muslim. The Globe and Mail reported in September 2019 that according to sources in the region, Christians likely number in the thousands.
