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.

Christianity was the largest religion in a high number of the countries included in the survey. Of the countries, Peru, South Africa, and Poland had the highest share of Christians at around 75 percent. Moreover, around 90 percent in India and Thailand stated that they believed in another religion, with Hinduism and Buddhism being the major religion in the two countries respectively. Sweden and South Korea were the only two countries where 50 percent or more of the respondents stated that they did not have any religious beliefs.

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.

Christianity is the main religion in Sub-Saharan Africa. As of 2020, over 650 million people in the region were Christian. Muslims followed, amounting to around 330 million, while folk religions counted over 33 million adherents. By 2050, the number of Christians in Sub-Saharan Africa is forecast to exceed 1.1 billion, Muslims are forecast to be around 670 million, and folk religions to account for about 61 million adherents.

In 2023, **** percent of Americans were unaffiliated with any religion. A further **** percent of Americans were White evangelical Protestants, and an additional **** percent were White mainline Protestants. Religious trends in the United States Although the United States is still home to the largest number of Christians worldwide, the nation has started to reflect a more diverse religious landscape in recent years. Americans now report a wide range of religious beliefs and backgrounds, in addition to an increasing number of people who are choosing to identify with no religion at all. Studies suggest that many Americans have left their previous religion to instead identify as atheist, agnostic, or nothing in particular, with many reasoning that they stopped believing in the religion's teachings, that they didn't approve of negative teachings or treatment of LGBTQ+ people, or that their family was never that religious growing up. Christian controversies Over the last few years, controversies linked to Christian denominations have plagued the nation, including reports of child sexual abuse by the Catholic Church, the Church of Jesus Christ of Latter-day Saints, and the Southern Baptist Convention. Christian churches have also been accused of supporting discriminatory actions against LGBTQ+ people and people belonging to other religious groups. In addition, there have been increasing concerns about Christian nationalism, the political ideology that asserts that America was founded to be a Christian nation. Although the majority of Americans still think that declaring the United States a Christian nation would go against the U.S. Constitution, studies found that most Republicans would be in favor of this change.

The 2000 constitution of Cote d’Ivoire provides for religious freedom for all citizens. Approximately 40 percent of the population is Christian, another 40 percent is Muslim, and an estimated 25 percent of the population practice indigenous beliefs. Traditionally, the north has been associated with Islam and the south with Christianity. Throughout rural areas and central Cote d’Ivoire you will find people practicing indigenous beliefs. Many nominal Christian and Muslim practitioners practice a hybrid of Christian and indigenous or Muslim and indigenous beliefs. Nearly all Christians and Muslims belong to ethnic groups that believe in animism, fetishism, and witchcraft. Christian groups include Roman Catholics, Jehovah’s Witnesses, Seventh-day Adventists, Methodists, Assemblies of God, and Southern Baptists. The Evangelical Protestant Church of Cote d’Ivoire has over 1500 organized churches in its membership. The Basilica of Our Lady of Peace of Yamoussoukro is a Roman Catholic basilica built in the late 1980s by then-President Felix Houphouet-Boigny. It is considered the largest church in the world. The USD 300 million price tag contributed to a significant portion to the total national debt of Cote d’Ivoire. Historically, Christian religions have been slightly favored by the government with the Catholic Church being the favorite. While Christian schools received subsidies from the Ministry of Education for decades, Muslim schools were only considered official schools and given similar subsidies beginning in 1994. Accusations of discrimination against Islamic and traditional religious communities concerned employment, national identity card renewals, and the aforementioned religious school subsidies. This resulted in government resentment from both indigenous and Muslim populations. A 1999 coup led political leaders to stir up religious divisions between the north and south. Alassane Ouattara, a Muslim northerner was banned from the 2000 election. This led to a 2002 troop mutiny and rebellion by discontent northern Muslims. Religious tensions escalated in 2010 with the presidential election results. Alassane Ouattara was elected president and incumbent President Laurent Gbagbo rejected the results and refused to step down. Ouattara is a northern Muslim, Gbagbo a southern Christian. The ensuing violence, destruction of property, and massive displacement of people divided Cote d’Ivoire into two regions, north and south. The underlying ethnic, religious, and national fragmentation of Cote d’Ivoire contributed greatly to this division. Only minor reports of discrimination based on religious affiliation, belief, or practice have occurred in 2012.

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.

Are different religions associated with different social, cognitive, and emotional tendencies? Although major world religions are known to encourage social interactions and help regulate emotions, it is less clear to what extent adherents of various religions differ in these dimensions in daily life. We thus carried out a large-scale sociolinguistic analysis of social media messages of Christians and Buddhists living in the United States. After controlling for age and gender effects on linguistic patterns, we found that Christians used more social words and fewer cognitive words than Buddhists. Moreover, adherents of both religions, similarly used more positive than negative emotion words on Twitter, although overall, Christians were slightly more positive in verbal emotional expression than Buddhists. These sociolinguistic patterns of actual rather than ideal behaviors were also paralleled by language used in the popular sacred texts of Christianity and Buddhism, with the exception that Christian texts contained more negative and fewer positive emotion words than Buddhist texts. Taken together, our results suggest that the direct or indirect influence of religious texts on the receivers of their messages may partially, but not fully, account for the verbal behavior of religious adherents.

Islam and Christianity form the two dominant religions in Nigeria. The basis of traditional religions was systematically exterminated in the religio-cultural life of the Nigerian people after their contact with colonialism. Approximately 90 percent of the Nigerian people have since preferred to be identified with either Islam or Christianity.Nigeria’s contact with Islam predated that of Christianity and European colonialism; its spread was facilitated into Sub-Saharan Africa through trade and commerce. The northern part of Nigeria is symbolic to the history of Islam, as it penetrated the area through the Kanem-Borno Empire in the 11th century before spreading to the other predominately Hausa states. Islam was then introduced into the traditional societies of the Yoruba-speaking people of south-west Nigeria through their established commercial relationship with people of the North, particularly the Nupe and Fulani.Christianity reached Nigeria in the 15th century with the visitation of the Roman and Catholic missionaries to the coastal areas of the Niger-Delta region, although there were few recorded converts and churches built during this period. Christianity soon recorded a boost in the southern region given its opposition to the slave trade and its promotion of Western education. In contrast to the smooth process Christian evangelization underwent in the South, its process in the North was difficult because Islam had already become well-established.Given the philosophy of Islam as a complete way of life for a Muslim, Islam has always been closely attached to politics in Nigeria. The emergence of particular Islamic groups was significantly influenced by international events, particularly the 1979 Iranian revolution and the corresponding disenchantment from the West. These developments shaped Nigerian national politics of the period as Muslims radically redefined their political interests in line with religion and began to clamor for the incorporation of the Sharia legal system into the country’s judicial system. Nigeria then tried to harness opportunities accruable from other Muslim countries by becoming a registered member with the Organization of Islamic Conference (OIC) in 1985. This inflamed Christians and nurtured the fear of domination by their Muslim counterparts and the possibility of a gradual extinction of their religio-political strength in the national political structure. The distinct religious separation has also instigated violence in present-day Nigeria, including the Sharia riot in Kaduna in 2000, ongoing ethno-religious violence in Jos since 2001, and the 2011 post-election violence that erupted in some northern states. Nigerians’ continued loyalty to religion compared to that of the country continues to sustain major political debate, conflict, and violent outbreaks between populations of the two faiths.
