As of 2010, Christianity was the religion with the most followers worldwide, followed by Islam (Muslims) and Hinduism. In the forty years between 2010 and 2050, it is projected that the landscape of world religions will undergo some noticeable changes, with the number of Muslims almost catching up to Christians. The changes in population sizes of each religious group is largely dependent on demographic development, for example, the rise in the world's Christian population will largely be driven by population growth in Sub-Saharan Africa, while Muslim populations will rise across various regions of Africa and South Asia. As India's population is set to grow while China's goes into decline, this will be reflected in the fact that Hindus will outnumber the unaffiliated by 2050. In fact, India may be home to both the largest Hindu and Muslim populations in the world by the middle of this century.

In 2020, around 28.8 percent of the global population were identified as Christian. Around 25.6 percent of the global population identify as Muslims, followed by 14.9 percent of global populations as Hindu. The number of Muslims increased by 347 million, when compared to 2010 data, more than all other religions combined.

From 2022 to 2060, the worldwide population of Muslims is expected to increase by 45.7 percent. For the same period, the global population of Buddhists is expected to decrease by 12.2 percent.

According to a survey conducted in South Korea in 2023, over ** percent of respondents reported no religious affiliation, while approximately ** percent identified as Christians and ** percent as Buddhists. Religious population South Korea is a multi-religious society where Christianity, Buddhism, and various other religions coexist with shamanism. According to a previous study, the domestic religious population appeared to decline over time after reaching its peak in 2005, at nearly ** million people. In contrast, the share of people who are religiously unaffiliated has increased in recent years. Within the last two decades, the religiously unaffiliated population has increased from about ** percent to more than ** percent. Shamanism Shamanism has continued to significantly influence the daily lives of many South Koreans. According to a survey conducted in 2023, about ** percent of respondents reported having consulted a fortune-teller within the past year. Roughly ** percent of those respondents were already affiliated with a religion.

The World Religion Project (WRP) aims to provide detailed information about religious adherence worldwide since 1945. It contains data about the number of adherents by religion in each of the states in the international system. These numbers are given for every half-decade period (1945, 1950, etc., through 2010). Percentages of the states' populations that practice a given religion are also provided. (Note: These percentages are expressed as decimals, ranging from 0 to 1, where 0 indicates that 0 percent of the population practices a given religion and 1 indicates that 100 percent of the population practices that religion.) Some of the religions are divided into religious families. To the extent data are available, the breakdown of adherents within a given religion into religious families is also provided.

The project was developed in three stages. The first stage consisted of the formation of a religion tree. A religion tree is a systematic classification of major religions and of religious families within those major religions. To develop the religion tree we prepared a comprehensive literature review, the aim of which was (i) to define a religion, (ii) to find tangible indicators of a given religion of religious families within a major religion, and (iii) to identify existing efforts at classifying world religions. (Please see the original survey instrument to view the structure of the religion tree.) The second stage consisted of the identification of major data sources of religious adherence and the collection of data from these sources according to the religion tree classification. This created a dataset that included multiple records for some states for a given point in time. It also contained multiple missing data for specific states, specific time periods and specific religions. The third stage consisted of cleaning the data, reconciling discrepancies of information from different sources and imputing data for the missing cases.

The National Religion Dataset: The observation in this dataset is a state-five-year unit. This dataset provides information regarding the number of adherents by religions, as well as the percentage of the state's population practicing a given religion.

In 2023, over ** percent of Indonesians declared themselves to be Muslim, followed by *** percent who were Christians. Indonesia has the largest Islamic population in the world and for this reason is often recognized as a Muslim nation. However, Indonesia is not a Muslim nation according to its constitution. The archipelago is a multifaith country and officially recognizes six religions – Islam, Protestantism, Catholicism, Buddhism, Hinduism, and Confucianism. Not all provinces in Indonesia are Muslim majority The spread of Islam in Indonesia began on the west side of the archipelago, where the main maritime trade routes were located. Until today, most of the Indonesian Muslim population are residing in Western and Central Indonesia, while the majority religion of several provinces in Eastern Indonesia, such as East Nusa Tenggara and Bali, is Christian and Hindu, respectively. Discrimination towards other beliefs in Indonesia The Indonesian constitution provides for freedom of religion. However, the Government Restrictions Index Score on religion in Indonesia is relatively high. Indonesians who practice unrecognized religions, including Indonesia’s indigenous or traditional belief systems, such as animism, dynamism, and totemism, face legal restrictions and discrimination. Indonesian law requires its citizens to put one of the recognized religions on their national identity cards, with some exceptions for indigenous religions. Although legally citizens may leave the section blank, atheism or agnosticism is considered uncommon in Indonesia.

This dataset shows the Worker Population Ratio (WPR), in percentage terms, for major religions, based on usual status (ps+ss). For years before 2017-18, the data was obtained in different quinquennial rounds of NSSO conducted from 2004-05 (NSS 61st) to 2011-12 (NSS 68th round). From 2017-18 the data is sourced from the annual report of the Periodic Labour Force Survey (PLFS) conducted by the Ministry of Statistics and Programme Implementation. The data highlights the proportion of the working population within major religious communities.

Time-series dataset of the demographic characteristics of the UK ethnic minority populations and religious groups up to 2006, to study ethnic and religious demographic diversity and its impact upon future population size, age-structure and the ethnic and religious composition of the UK population. This dataset is compiled from various existing data sources: 2001 Census, Labour Force Survey (LFS) and International Passenger Survey (IPS) data. In the absence of vital statistics by ethnic groups, indirect methods were used to estimate vital rates, including the ‘Own Child’ method applied to LFS household data to derive fertility estimates of ethnic and religious groups. Building on previous work, fertility rates of ethnic groups were produced up to 2006, distinguishing between UK-born and foreign-born populations. Migration rates were based on ONS International Migration Statistics (using IPS data), LFS and census data and projected on various assumptions. The results served population projections to mid-century and beyond of the main ethnic minority populations, including mixed populations, and using cohort-component methods. Furthermore, estimates of fertility rates for the major religious (and non-religious) groups were produced.

Datasets include: (1) Calculated fertility estimates for all women aged 15 to 49 in the UK, by 5 years age group, by ethnic group, religion and place of birth (UK/non-UK), based on LFS data; (2) Data on mixed children by ethnic group of the mother; (3) Data on country of birth by ethnic group (all populations); (4) Data on immigration flow by country of origin.

This project aims to analyse ethnic and religious demographic diversity, to investigate the potential for convergence of trends over time and its impact upon future population size, age-structure and the ethnic and religious composition of the UK population.

Existing statistical sources (especially the 2001 Census, the Labour Force Survey (LFS) and the Office for National Statistics (ONS) Longitudinal Survey) will be used to produce time-series of the demographic characteristics of the ethnic minority populations and religious groups up to 2006. In the absence of vital statistics by ethnic groups, the Own Child method applied to LFS and census data will be used to derive fertility estimates of ethnic and religious groups.

The results will serve population projections to mid-century and beyond of the main ethnic minority populations, including mixed populations, and using cohort-component methods. Migration rates will be based on ONS International Migration Statistics, LFS and census data and projected on various assumptions.

Furthermore, estimates of fertility rates and other demographic information for the major religious (and non-religious) groups will be produced with a view to making preliminary projections of their future size. The potential convergence of the demographic characteristics of ethnic and religious groups will be analysed, including mixed unions as an indicator for integration.

Census 2021 data on religion by highest qualification level, by sex, by age, England and Wales combined. This dataset provides Census 2021 estimates that classify usual residents in England and Wales by ethnic group. The estimates are as at Census Day, 21 March 2021.

The religion people connect or identify with (their religious affiliation), whether or not they practise or have belief in it.
This question was voluntary and the variable includes people who answered the question, including “No religion”, alongside those who chose not to answer this question.

Total counts for some population groups may not match between published tables. This is to protect the confidentiality of individuals' data. Population counts have been rounded to the nearest 5 and any counts below 10 are suppressed, this is signified by a 'c' in the data tables.

This dataset shows population counts for usual residents aged 16 years and over. Some people aged 16 years old will not have completed key stage 4 yet on census day, and so did not have the opportunity to record any qualifications on the census.

These estimates are not comparable to Department of Education figures on highest level of attainment because they include qualifications obtained outside England and Wales.
