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.

Historically, Portugal has been a country of Catholics. The 2021 census demonstrated that this trend has not been inverted, as over 80 percent of the population in Portugal identified as Catholic. Protestant or Evangelic believers accounted for more than two percent of the population, while Jehovah's Witnesses constituted one percent of residents. Among non-Christian faiths, Muslims were the most representative group, making up 0.42 percent of the population.

Religious but generally not practicing the faith

In the same year, Catholics numbered more than seven million people spread throughout the country, conquering the religious majority in the mainland and in the two autonomous regions. Citizens without religion totaled more than 1.2 million, which made of them the second most numerous religious group in Portugal. Young people presented the same religious trend, with young Catholics being the most representative group, followed by non-religious. Among youngsters, the attendance of religious events was mostly conducted occasionally, while a quarter did not participate in such proceedings at all.

The contribute of immigration to the growth of Evangelical Christianity

Despite being the minority, non-Catholic Christian and non-Christian faiths have been growing in Portugal. In 2011, Evangelical believers totaled 75.6 thousand, more than doubling ten years after. Such growth was partially motivated by the increase in Brazilian immigration, as more than 61 percent of new members of Evangelical churches in 2023 were of Brazilian origin. In fact, Brazil was the place of origin of almost 82 percent of all the immigrant Evangelical Christians residing in Portugal. However, more than a quarter of new Evangelical Christians were Portuguese, which shows that other religions, namely Christian Catholicism, have been losing members to Evangelical Catholicism.

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).

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.

This statistic presents the perceived proportion of Muslim citizens (out of 100) in Europe in 2018. According to data published by Ipsos, with the exception of Turkey, all the countries in this statistic overestimated the number of Muslims in their country.

In 2023, over 87 percent of Indonesians declared themselves to be Muslim, followed by 7.4 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.

Roman Catholic is the most common religious affiliation in Colombia. In a survey carried out in 2023, nearly 64 percent of Colombian respondents claimed to be of Catholic faith, whereas the second most chosen religion was Evangelism, with 15.7 percent of the people interviewed. More than 14 percent of respondents answered they had no religious affiliation. The advent of evangelicalism in Colombia and LAC The share of Catholics in Colombia is above the average in Latin America and the Caribbean, where about 53 percent of adults identify as followers of Catholicism. Nevertheless, even if Colombia stood out historically as one of the countries with the largest share of Catholics in the region, their numbers have been dwindling considerably in the past few decades: in the year 2000, 85.5 of Colombians identified as Catholics, over 15 percent points more than two decades later. Meanwhile, Evangelism keeps gaining ground in both the country and the region. While merely 3.4 percent of Colombians were evangelical in 1996, this share had grown almost five-fold by 2020, while atheists and agnostics passed from 4.5 to 10.3 in the same lapse of time. The whole of Latin America is experiencing a similar trend, with evangelists accounting for more than one fifth of the population in countries such as Guatemala, Costa Rica, and Brazil. The success of Evangelical Churches in Latin America is related, among other things, to the creation of social safety nets in poor communities, the rise of conservative political parties and movements, and more flexible standards for ordination.
Religiosity among young Colombians Interestingly, eastern religions such as Buddhism enjoy the same popularity as Evangelism and Protestantism among young Colombians. Religion seems to have a considerable impact on youngsters’ life. More than half of surveyed Colombians aged between 15 and 29 claimed that religious beliefs provided them with inner peace, while another 12.5 and 10 percent said that it helped them to quit drugs and gangs, respectively. Only 5.5 percent of the respondents affirmed that religious beliefs had no influence on their lives. As for the religiosity of young Catholic Colombians, very few claimed to be very observant. Around 45 percent considered themselves not very observant, while around a third classified as somewhat observant.

This statistic shows the results of a global survey on faith in God or a supreme being. The survey was conducted in 23 countries in September 2010. 70 percent of respondents in the United States stated they believe in God or a higher being.

Religious adherence varies widely between countries and regions across the globe. While in some countries, such as Bangladesh (majority-Muslim), Thailand (majority-Buddhist), and Nigeria (over 50 percent Muslim and 45 percent Christian), almost all people indicate that religion is important in their daily lives, in others such as Japan, Sweden, and Estonia, over three quarters of people do not believe that religion is important to them. Among countries with higher levels of religious adherence, there are some interesting cases. Predominantly Islamic countries, such as Bangladesh, Indonesia, and Saudi Arabia, tend to show high levels of religious adherence. Italy, the historical center of the Catholic Church, records much higher levels of religiosity than other Western European countries, such as France, Germany, or the UK. The United States has almost double the number of people saying they believe religion is important in their daily life than not important. While religious adherence has declined over the past half century in the U.S., waves of immigration from predominantly Catholic countries, as well as the cultural impact of Evangelical Protestantism in some areas has meant that it is still one of the most religious Western countries. Israel, in spite of being an officially Jewish state, records roughly half of respondents being religious. Another notable trend is the tendency of some post-communist countries to show lower levels of religiosity, likely a result of the policy of state atheism under communism - Russia, Belarus, and Estonia all come towards the least religious end of the list for this reason, although Poland, or former-Soviet states in the Caucuses and Central Asia show much higher levels of religious adherence.
