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.

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 (as detailed below) 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 Global Religion Dataset: This dataset uses a religion-by-five-year unit. It aggregates the number of adherents of a given religion and religious group globally by five-year periods.

Islam is the major religion in many African countries, especially in the north of the continent. In Comoros, Libya, Western Sahara, at least 99 percent of the population was Muslim as of 202. These were the highest percentages on the continent. However, also in many other African nations, the majority of the population was Muslim. In Egypt, for instance, Islam was the religion of 79 percent of the people. Islam and other religions in Africa Africa accounts for an important share of the world’s Muslim population. As of 2019, 16 percent of the Muslims worldwide lived in Sub-Saharan Africa, while 20 percent of them lived in the Middle East and North Africa (MENA) region. Together with Christianity, Islam is the most common religious affiliation in Africa, followed by several traditional African religions. Although to a smaller extent, numerous other religions are practiced on the continent: these include Judaism, the Baha’i Faith, Hinduism, and Buddhism. Number of Muslims worldwide Islam is one of the most widespread religions in the world. There are approximately 1.9 billion Muslims globally, with the largest Muslim communities living in the Asia-Pacific region. Specifically, Indonesia hosts the highest number of Muslims worldwide, amounting to over 200 million, followed by India, Pakistan, and Bangladesh. Islam is also present in Europe and America. The largest Islamic communities in Europe are in France (5.72 million), Germany (4.95 million), and the United Kingdom (4.13 million). In the United States, there is an estimated number of around 3.45 million Muslims.

When asked about their personal attitude towards various religions in Australia, ** percent of Australians surveyed had a negative attitude towards Muslims. Buddhists appeared to be least likely to elicit negative responses and around ** percent of respondents responded negatively to Christians.

 Islam in Australia

Muslims represent almost a quarter of the religious diversity in the Asia Pacific region and Australia’s neighbor, Indonesia, has the largest Muslim population in the world. In Australia, Islam is the second largest religious group but less than ***** percent of the population are Muslim, compared to over ** percent of the population identifying as Christian. The Australian Muslim community is very diverse, consisting of migrants from Bangladesh, Lebanon, Turkey, as well as Australian-born Muslims of European heritage.

 Australians increasingly less religious

The 2016 Australian census revealed that an ever-increasing number of Australians are selecting “no religion” in the optional census question on religious affiliation. This drop in religious affiliation is a common trend in many economically developed countries, although some of Australia’s minority religions like Islam and Buddhism are still showing some growth. In contrast, Christianity appears to be declining, especially amongst people under the age of **, an age group that also recorded higher numbers of people with no religion.

The RCS-Dem dataset reports estimates of religious demographics, both country by country and region by region. RCS was created to fulfill the unmet need for a dataset on the religious dimensions of countries of the world, with the state-year as the unit of observation. It covers 220 independent states, 26 selected substate entities, and 41 geographically separated dependencies, for every year from 2015 back to 1900 and often 1800 (more than 42,000 state-years). It estimates populations and percentages of adherents of 100 religious denominations including second level subdivisions within Christianity and Islam, along with several complex categories such as "Western Christianity." RCS is designed for easy merger with datasets of the Correlates of War and Polity projects, datasets by the United Nations, the Religion And State datasets by Jonathan Fox, and the ARDA national profiles.

The landscape of religious organizations has evolved, reflecting broader societal shifts and economic variables. These institutions have adapted to challenges by embracing digital platforms and enhancing community engagement, leveraging technological innovations to maintain spiritual connections. Economic fluctuations have also impacted how people donate, yet organizations have successfully navigated these changes by offering online donation options and fostering community bonds. Diversification in revenue streams and focusing on inclusivity have allowed many groups to maintain positive revenue growth. Cultural dynamics emphasizing equality have prompted many to adopt practices that resonate with contemporary values, further supporting their mission and outreach. Industry-wide revenue is expected to rise at a CAGR of 0.5% over the past five years, including an estimated 2.5% expansion in 2025 and a total of $159.8 billion. Religious entities have demonstrated resilience, with profitability supported by strategic financial management. Wages constitute a substantial part of budgets, particularly for larger organizations, but careful planning ensures funds are allocated efficiently. Religious entities have managed to end fiscal years with budget surpluses, attributed to diligent cost control and donor support. Digital engagement has become a cornerstone for sustaining financial contributions, allowing steady income and reduced dependency on in-person donations. Though shifting economic conditions posed revenue fluctuations, strategic planning and community-centric approaches have driven ongoing resilience and sustainability. The anticipated trajectory for these organizations suggests a continued embrace of innovative outreach and technology to bolster engagement. Organizations will likely enhance efforts to connect with younger demographics, shaping experiences that align with evolving cultural preferences. The expected rise in donations, influenced by demographic changes and economic stability, presents opportunities for expanded programs and community outreach. By staying attuned to societal shifts and integrating technology, religious groups aim to maintain their relevance and engage broader audiences. The future promises growth through diversified funding, engagement strategies targeting younger members and leveraging technological advancements to strengthen spiritual and communal ties. Industry revenue is expected to boost at a CAGR of 1.4% over the next five years, reaching $171.6 billion in 2030.

The statistic shows the total population of India from 2019 to 2029. In 2023, the estimated total population in India amounted to approximately 1.43 billion people.

Total population in India

India currently has the second-largest population in the world and is projected to overtake top-ranking China within forty years. Its residents comprise more than one-seventh of the entire world’s population, and despite a slowly decreasing fertility rate (which still exceeds the replacement rate and keeps the median age of the population relatively low), an increasing life expectancy adds to an expanding population. In comparison with other countries whose populations are decreasing, such as Japan, India has a relatively small share of aged population, which indicates the probability of lower death rates and higher retention of the existing population.

With a land mass of less than half that of the United States and a population almost four times greater, India has recognized potential problems of its growing population. Government attempts to implement family planning programs have achieved varying degrees of success. Initiatives such as sterilization programs in the 1970s have been blamed for creating general antipathy to family planning, but the combined efforts of various family planning and contraception programs have helped halve fertility rates since the 1960s. The population growth rate has correspondingly shrunk as well, but has not yet reached less than one percent growth per year.

As home to thousands of ethnic groups, hundreds of languages, and numerous religions, a cohesive and broadly-supported effort to reduce population growth is difficult to create. Despite that, India is one country to watch in coming years. It is also a growing economic power; among other measures, its GDP per capita was expected to triple between 2003 and 2013 and was listed as the third-ranked country for its share of the global gross domestic product.

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.

Christianity is the major religion in numerous African countries. As of 2024, around 96 percent of the population of Zambia was Christian, representing the highest percentage on the continent. Seychelles and Rwanda followed with roughly 95 percent and 94 percent of the population being Christian, respectively. While these countries present the highest percentages, Christianity was also prevalent in many other African nations. For instance, in South Africa, Christianity was the religion of nearly 85 percent of the people, while the share corresponded to 71 percent in Ghana. Religious variations across Africa Christianity and Islam are the most practiced religions in Africa. Christian adherents are prevalent below the Sahara, while North Africa is predominantly Muslim. In 2020, Christians accounted for around 60 percent of the Sub-Saharan African population, followed by Muslims with a share of roughly 30 percent. In absolute terms, there were approximately 650 million Christians in the region, a number forecast to increase to over one billion by 2050. In contrast, Islam is most prevalent in North Africa, being the religion of over 90 percent of the population in Algeria, Morocco, Tunisia, and Libya. Christianity in the world As opposed to other religions, Christianity is widely spread across continents worldwide. In fact, Sub-Saharan Africa, Latin America and the Caribbean, and Europe each account for around 25 percent of the global Christian population. By comparison, Asia-Pacific and North America make up 13 percent and 12 percent of Christians worldwide, respectively. In several regions, Christians also suffer persecution on religious grounds. Somalia and Libya presented the most critical situation in Africa in 2021, reporting the strongest suppression of Christians worldwide just after North Korea and Afghanistan.

The Hajj to Mecca in Saudi Arabia is considered among the world’s largest human gatherings, with over **** million pilgrims in 2025. The Saudi government restricted Hajj to residents in Saudi Arabia only during the COVID-19 pandemic in 2020. The number of Hajj pilgrims dropped to about **** thousand in 2021. Like other religious pilgrimages, Hajj is considered an annual rite of passage to renew one's moral and spiritual connection. Approximately a quarter of the human population identify themselves as Muslims. According to their faith of Islam, it is one of their five religious duties to perform the Hajj at least once in their lifetime. Who are the pilgrims? According to Islamic tradition, any Muslim who has reached maturity is due to perform the Hajj. During the last Hajj season before the COVID-19 pandemic, about two thirds of the pilgrims to Mecca came from outside of the Saudi Arabian Kingdom. The government of Saudi Arabia issues each years’ Hajj visas on a country quota system, based on the size of the Muslim population .     Financial aspects   One main condition for a mature Muslim to qualify to perform the Hajj is to be free of debt and other financial and social obligations. Many Muslims around the world spend a significant amount of their life-savings to be able to make this spiritual journey. As an example, the cost of performing Hajj for a Malaysian Muslim was calculated at about ***** thousand Malaysian ringgits. For first time Hajj pilgrims, the Malaysian government subsidizes more than half of that amount. Some Muslims who can’t afford the financial or physical challenges of the Hajj sometimes perform the smaller Islamic pilgrimage to Mecca called Umrah, which can be attempted all year round.

The majority of Japanese adhere to Shintoism, a traditional Japanese religion focusing on rituals and worship at shrines. In 2021, around 48.6 percent of the total population of Japan participated in Shinto practices. Closely behind is Buddhism, with more than 46 percent of the population adhering to its practices. Most Japanese thus practice both religions. The original ShintoShintoism adherents worship spirits or gods at shrines, often publicly, through rituals and traditions. Shintoism is deeply ingrained in the Japanese culture and way of life, but the number of followers has been decreasing over the past years, as has the number of Japanese who are adhering to any kind of religion. Tradition seems to have to make way for modern attitudes and choices – still the number of people who call themselves Shinto adherents is quite high, even if they do not actively practice it. Everything zen in BuddhismWhile Shintoism seems to become a thing of the past, the number of Buddhists, on the other hand, has been stable over the last decade, and if anything, has only slightly decreased. Japan is, in fact, among the countries with the largest Buddhist communities, right after China, of course, and Thailand. This might be due to Buddhism being able to adapt much easier to modern times and its adherents’ everyday lives, as well as a better PR machine – Buddhism is, after all, also quite popular in the Western world.

In 2021, 53.3 percent of the total population in Canada were Christian, 4.9 percent were Muslim, but almost more than a third are not religious at all – with the rest stating they adhere to Hinduism, Sikhism, Buddhism, the Jewish faith, and other Christian denominations. Canada’s religious pluralismCanada is not a very religious country in general. Canadians adhere to a wide variety of beliefs and faiths, with the majority following Christianity, followed by those who do not believe in any deity or religion at all. As with many Western countries, the younger generations are less inclined to identify with faith, and Christianity in particular is not as popular as it is among the older generations. Alternative worship for the younger generations?Canadian teenagers are no less enthusiastic about religion than their parents, and they are just as grounded in their faith as the older generations. They are, however, also just as indecisive when it comes to whether they would call themselves religious or not. Interestingly, they seem much more interested in traditional aboriginal spirituality than in the Judeo-Christian model. They also seem quite interested in another alternative to Christianity: Buddhism is quite popular among the younger generations. Whether this signifies a general trend away from Christianity and towards religious alternatives remains to be seen.

In 1800, the population of the region of present-day India was approximately 169 million. The population would grow gradually throughout the 19th century, rising to over 240 million by 1900. Population growth would begin to increase in the 1920s, as a result of falling mortality rates, due to improvements in health, sanitation and infrastructure. However, the population of India would see it’s largest rate of growth in the years following the country’s independence from the British Empire in 1948, where the population would rise from 358 million to over one billion by the turn of the century, making India the second country to pass the billion person milestone. While the rate of growth has slowed somewhat as India begins a demographics shift, the country’s population has continued to grow dramatically throughout the 21st century, and in 2020, India is estimated to have a population of just under 1.4 billion, well over a billion more people than one century previously. Today, approximately 18% of the Earth’s population lives in India, and it is estimated that India will overtake China to become the most populous country in the world within the next five years.

In 2023, the population of Bali, Indonesia, amounted to around *** million people. The Hindu population in Bali accounts for about ** percent of its total population, and the island is well known for its rich culture, religious practices, and traditions. While Buleleng is the largest regency in the province, the highest population density is found in Denpasar, the capital and primary hub of Bali.   Tourism economy in Bali Bali is considered one of the world’s most famous islands, offering picturesque natural settings and vibrant culture, attracting large numbers of both local and international visitors. As of the first quarter of 2023, more than *** million foreign tourists visited the island, with most international travelers to Bali coming from Australia. Bali also stands as the most preferred domestic travel destination among Indonesians, making tourism a vital sector of its economy.   Balinese agricultural foundations Besides travel and tourism, Bali is also closely tied to agriculture, forestry, and fishing, as these sectors provide work opportunities for a significant part of the population. The tropical island is renowned for some primary commodities, such as coconuts, cocoa, and coffee, which dominate its overall crop production. Furthermore, paddy fields, a striking part of Bali’s landscape in many areas of the island, cover more than ** percent of its total land area, conveying its agrarian roots. Paddy fields are commonly utilized to cultivate rice, one of the staple foods of Indonesians. Tabanan and Gianyar are among the Balinese regencies producing the highest quantities of rice.

During the eighteenth century, it is estimated that France's population grew by roughly fifty percent, from 19.7 million in 1700, to 29 million by 1800. In France itself, the 1700s are remembered for the end of King Louis XIV's reign in 1715, the Age of Enlightenment, and the French Revolution. During this century, the scientific and ideological advances made in France and across Europe challenged the leadership structures of the time, and questioned the relationship between monarchial, religious and political institutions and their subjects. France was arguably the most powerful nation in the world in these early years, with the second largest population in Europe (after Russia); however, this century was defined by a number of costly, large-scale conflicts across Europe and in the new North American theater, which saw the loss of most overseas territories (particularly in North America) and almost bankrupted the French crown. A combination of regressive taxation, food shortages and enlightenment ideologies ultimately culminated in the French Revolution in 1789, which brought an end to the Ancien Régime, and set in motion a period of self-actualization.

War and peace

After a volatile and tumultuous decade, in which tens of thousands were executed by the state (most infamously: guillotined), relative stability was restored within France as Napoleon Bonaparte seized power in 1799, and the policies of the revolution became enforced. Beyond France's borders, the country was involved in a series of large scale wars for two almost decades, and the First French Empire eventually covered half of Europe by 1812. In 1815, Napoleon was defeated outright, the empire was dissolved, and the monarchy was restored to France; nonetheless, a large number of revolutionary and Napoleonic reforms remained in effect afterwards, and the ideas had a long-term impact across the globe. France experienced a century of comparative peace in the aftermath of the Napoleonic Wars; there were some notable uprisings and conflicts, and the monarchy was abolished yet again, but nothing on the scale of what had preceded or what was to follow. A new overseas colonial empire was also established in the late 1800s, particularly across Africa and Southeast Asia. Through most of the eighteenth and nineteenth century, France had the second largest population in Europe (after Russia), however political instability and the economic prioritization of Paris meant that the entire country did not urbanize or industrialize at the same rate as the other European powers. Because of this, Germany and Britain entered the twentieth century with larger populations, and other regions, such as Austria or Belgium, had overtaken France in terms of industrialization; the German annexation of Alsace-Lorraine in the Franco-Prussian War was also a major contributor to this.

World Wars and contemporary France

Coming into the 1900s, France had a population of approximately forty million people (officially 38 million* due to to territorial changes), and there was relatively little growth in the first half of the century. France was comparatively unprepared for a large scale war, however it became one of the most active theaters of the First World War when Germany invaded via Belgium in 1914, with the ability to mobilize over eight million men. By the war's end in 1918, France had lost almost 1.4 million in the conflict, and approximately 300,000 in the Spanish Flu pandemic that followed. Germany invaded France again during the Second World War, and occupied the country from 1940, until the Allied counter-invasion liberated the country during the summer of 1944. France lost around 600,000 people in the course of the war, over half of which were civilians. Following the war's end, the country experienced a baby boom, and the population grew by approximately twenty million people in the next fifty years (compared to just one million in the previous fifty years). Since the 1950s, France's economy quickly grew to be one of the strongest in the world, despite losing the vast majority of its overseas colonial empire by the 1970s. A wave of migration, especially from these former colonies, has greatly contributed to the growth and diversity of France's population today, which stands at over 65 million people in 2020.

In 2025, North Korea was the country with the strongest suppression of Christians with an index value of 98. Somalia followed behind with 94, with Yemen in third. The World Watch List The index ranges from 0 (complete freedom) to 100 (total suppression). The survey for the World Watch List included various aspects of religious freedom: the legal and official status of Christians, the actual situation of Christians living in the country, regulations from the state as well as factors that can undermine the freedom of religion in a country. Christianity worldwideEven though Christianity is the largest religion worldwide, there are many areas of the world where Christians are persecuted. As the list shows, this is especially the case in countries with larger Muslim populations. Moreover, these countries are characterized by their authoritarian nature. The global distribution of religions varies strongly; whereas almost 100 percent of Hindus and Buddhists are found in the Asia-Pacific, Christians are spread around most world regions except the Middle East and North Africa.

In 2024, there were around 394,608 divorces involving Muslim marriages, a decrease in compared to the previous year. 2022 saw a peak in divorces, reaching an all-time high for the past decade. The rise in divorce cases indicated a growing acceptance of the practice. Even so, divorcing in Indonesia can have serious consequences, especially for women. Muslim marriages in Indonesia Indonesia has the world’s largest Muslim population, and they are served by the religious courts with regards to matters concerning marriage and divorce, inheritance, and property. In 2022, almost two million Muslim marriages took place in Indonesia, including informal registrations. Under Syariah law, Muslims are permitted to marry once they reach sexual maturity. This has led to a widespread practice of forced child marriage in Indonesia. In September 2019, the Indonesian parliament passed a bill to raise the minimum age of marriage for women from 16 years to 19 years. Financial burden of divorce Forced marriage was cited as a ground for divorce in *** cases in 2022. The second-most commonly cited grounds for divorce, however, were financial problems and difficulties. Unfortunately, for many women, the financial difficulties would not end with divorce – in fact, it may just be the beginning. Men are typically the primary breadwinner in Indonesia, leaving many women financially dependent on their husbands. As of 2021, only half of Indonesian women had an account in a financial institution. Meanwhile, custody of the children is usually awarded to the woman after a divorce. This leaves many Indonesian women without financial support, and the additional burden of having children to raise alone. Despite the decreasing stigma of divorce, many women might still choose to stay in a bad marriage to avoid being put in a financially precarious situation.

Muslims residing in Oslo, Norway will be fasting in the middle of the month of Ramadan for a total of ** hours and ** minutes, between the times of **** am and **** pm. During the Islamic holy month of Ramadan, observing Muslims worldwide abstain from eating, drinking, smoking, and sexual activities from sunrise to sunset.RamadanThe Islamic calendar is based on the lunar year; therefore, it is ten days shorter than the Gregorian solar calendar. Thus, Ramadan will take place from the 1st to the 29th of March 2025. The fasting hours are calculated from dusk until dawn of each day for the whole of the month of Ramadan. Differing fasting times in different places result from the fact that the length of each day varies based on the latitude of each location and changes each day due to the Earth's orbit around the sun. However, there might be slight interpretational differences between different schools of thought and branches of Islam. Muslim worldAccording to the latest estimations there are over *** billion Muslims worldwide. It is estimated that that by 2026 the Muslim population will increase to over **** billion narrowing the gap with Christianity, whose community is projected to grow to just over ***** billion by then. The majority of Muslims worldwide are located in Asia, though it is only a quarter of the continent’s population.

In 2022, the marriage rate in the United States stood at *** per 1,000 people of the population. This is a decrease from 1990 levels, when the marriage rate was *** marriages per 1,000 people. Marriage Marriage is a union that can legally, culturally, and financially bind two people. Marriage occurs between all genders, races, and cultures, and is often drastically different all around the world, due to the diversity of cultures and religions. Marriage can be recognized by a state, religious authority, or an organization. Typically viewed as a contract, it brings people together through a multitude of avenues. A part of marriage is the wedding, for which couples can decide to partake in or not. Weddings are also incredibly diverse and vary in time, money, and customs. Marriage in the United States Marriage in the United States is viewed differently across all 50 states. The number of married couples in the United States has been steadily increasing since 1960. On the other hand, the divorce rate in the United States has decreased since 1990. Nevada was the state in 2021 that had the highest marriage rate in the United States, due to easy accessibility to get married there. In 2021, Nevada was also the state with the highest divorce rate in the country.
