The U.S. government estimates the total population at 1.4 billion (midyear 2021).  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 1 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 Buddhists, 60 to 80 million Protestants, 21 to 23 million Muslims, seven to 20 million Falun Gong practitioners, 12 million Roman Catholics, six to eight million Tibetan Buddhists, and hundreds of millions who follow various folk traditions.  According to Boston University’s 2020 World Religion Database, there are 499 million folk and ethnic religionists (34 percent), 474 million agnostics (33 percent), 228 million Buddhists (16 percent), 106 million Christians (7.4 percent), 100 million atheists (7 percent), 23.7 million Muslims (1.7 percent), and other religions adherents who together constitute less than 1 percent of the population, including 5.9 million Taoists, 1.8 million Confucians, 20,500 Sikhs, and 2,900 Jews.  According to the Christian advocacy NGO Open Doors USA’s World Watch List 2022 report, there are 96.7 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.  A June report on the Xinjiang Uyghur Autonomous Region (Xinjiang) issued by the Department of Population and Employment Statistics of the PRC’s National Bureau of Statistics estimates the total population in Xinjiang is 26 million.  The report states Uyghurs, along with ethnic Kazakh, Hui, Kyrgyz, and members of other predominantly Muslim ethnic minority groups, number approximately 15 million residents, or 58 percent of the total population there.

While there is no reliable government breakdown of the Buddhist population by school, the vast majority of Buddhists are adherents of Mahayana Buddhism, according to the Pew Research Center.  Most ethnic Tibetans practice Tibetan Buddhism, although a sizeable minority practices Bon, a pre-Buddhist indigenous religion.

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 a religious practice.

The U.S. government estimates the total population at 68.1 million (midyear 2021).  ccording to a January 2020 report released by the government-appointed Observatory for Secularism, based on a poll conducted in cooperation with polling company Viavoice, approximately 47 percent of respondents identify as Catholic, 3 percent Muslim, 3 percent Protestant, 2 percent Buddhist, 1 percent Jewish, 1 percent Christian Orthodox, and 1 percent other religious groups; 34 percent said they have no religious affiliation and 8 percent preferred not to respond.  According to the observatory’s 2019 report, there are 140,000-150,000 Jehovah’s Witnesses and 150,000-300,000 Hindus.  In a poll on secularism released in February and conducted with Viavoice, 35 percent of respondents say they are believers, 30 percent nonbelievers or atheist, 14 percent agnostic, and 13 percent indifferent.  Most observers, including the observatory in its 2019 report, estimate the number of Muslims in the country at three to five million, or between 4 and 7 percent of the population.  According to Church of Scientology leaders, there are approximately 40,000 followers in the country.

A poll by the research firm French Institute of Public Opinion (IFOP) conducted August 24-25 found that 51 percent of respondents said they do not believe in God, and 49 percent said they do.  According to the IFOP poll, the highest percentage of believers (58 percent) was found among those 65 years and older and the lowest (45 percent) among those aged 35-49.  Other age groups were close to evenly split, with a slight majority of nonbelievers.

The U.S. government estimates the total population at 79.9 million (midyear 2021).  Unofficial estimates based on the census and figures provided by religious groups indicate approximately 27 percent of the population is Catholic and 25 percent belongs to the Evangangelische Kirche in Deutschland (EKD) – a confederation of Lutheran, Reformed (Calvinist), and United (Prussian Union) Protestant regional churches.  Other Protestant denominations, including the New Apostolic Church, Baptist communities, and nondenominational Christians, account for approximately 2 percent of the population.  Orthodox Christians represent 1.9 percent of the population.

According to government estimates published in April, approximately 6.6 percent of the population is Muslim, of which 74 percent is Sunni, 8 percent Alevi, 4 percent Shia, 1 percent Ahmadi, and 1 percent other affiliations such as Alawites and Sufis.  The remaining 12 percent of Muslims in the country say they are not affiliated with any of the above groups or are unwilling to disclose an affiliation.  Intelligence officials estimate there are approximately 12,150 Salafi Muslims in the country.  Estimates of the Jewish population vary widely; the Federal Ministry of the Interior estimates it at 95,000, while other estimates place the number at approximately 190,000 when including Jews who do not belong to a specific Jewish community.  According to the secular NGO Religious Studies Media and Information Service (REMID), Buddhists (270,000); Jehovah’s Witnesses (167,000); Hindus (100,000); Yezidis (100,000); members of The Church of Jesus Christ of Latter-day Saints (Church of Jesus Christ) (40,000); Sikhs (10,000-15,000); and members of the COS (3,400) together constitute less than 1 percent of the population.  All of REMID’s estimates are based on members who have registered with a religious group.  According to the nonprofit Research Group Worldviews Germany, approximately 39 percent of the population either has no religious affiliation or belongs to religious groups not counted in government statistics.

The U.S. government estimates the total population at 7.3 million (midyear 2021).  According to SAR government statistics, there are more than one million followers of Taoism and approximately one million followers of Buddhism; 800,000 Protestants; 404,000 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 621,000 followers (404,000 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 630,000 (midyear 2021).  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 2021 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 is Roman Catholic, of whom almost half are foreign domestic workers and other expatriates, and 2.5 percent of the population is Protestant.  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 2020 estimate of the National Bureau of Statistics of China, the total population of the TAR is approximately 3,648,000, 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.  The majority of ethnic Tibetans in the PRC live in the TAR, in Tibetan autonomous prefectures (TAPs), and in counties in Qinghai, Sichuan, Gansu, and Yunnan Provinces.  Official census data show Tibetans constitute approximately 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 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 June report on the XUAR issued by the Department of Population and Employment Statistics of the National Bureau of Statistics estimates the total population is 26 million.  The report states Uyghurs, along with Kazakh, Hui, Kyrgyz, and members of other predominantly Muslim ethnic minority groups constitute approximately 15 million residents in Xinjiang, or approximately 58 percent of the total population.  According to the report, of these, 12 million are Uyghurs.  The largest segment of the remaining population is Han Chinese (11 million, approximately 42 percent), with additional groups including Mongols, Tibetans, and others constituting less than 1 percent.  Uyghurs are overwhelmingly Sunni Muslims.  The Globe and Mail reported in September 2019 that according to sources in the region, Uyghur and Han Chinese Christians likely number in the thousands.
