The average for 2013 based on 84 countries was 43.2 percent. The highest value was in Poland: 95.2 percent and the lowest value was in Ethiopia: 0.6 percent. The indicator is available from 1960 to 2013. Below is a chart for all countries where data are available.

Brazil is the largest Catholic country in the world, with an estimated Catholic population of 140 million, ahead of Mexico and the Philippines, with 101 million and 85 million Catholics, respectively. Nevertheless, Brazil's Catholic population is shrinking. By 2050, today's largest Catholic country could have a majority Protestant population.

Except for Uruguay, over ** percent of the population in all the selected Latin American countries defined themselves as Catholics in 2000. However, by 2023, that was the case in only three countries: Mexico, Peru and Colombia. Over this 20-year period, Panama experienced the largest decrease in the share of Catholic believers, plummeting from **** to **** percent.

The average for 2013 based on 20 countries was 31 percent. The highest value was in Cape Verde: 87.8 percent and the lowest value was in Ethiopia: 0.6 percent. The indicator is available from 1960 to 2013. Below is a chart for all countries where data are available.

Guatemala was the most Christian country among those selected in the Latin America and Caribbean region, with **** percent of its population following Christianity in 2023. The Baháʼí faith, which originates from the Middle East, and preaches the unity of all religions and all people, was present in both Bolivia and Panama. As for agnosticism, it had the most practitioners in Uruguay and Cuba.

In 2020, Mexico had a protestant and evangelical population of ********** people, the second most followed religion in the country, just behind Catholicism. During that year, **** percent of that population was 60 years of age or older. The second age group with the most catholic followers was between 10 and 14 years of age, with *** percent.

Roman Catholic is the most common religious affiliation in Colombia. In a survey carried out in 2023, nearly ** percent of Colombian respondents claimed to be of Catholic faith, whereas the second most chosen religion was Evangelism, with **** percent of the people interviewed. More than ** 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 ** 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, **** of Colombians identified as Catholics, over ** percent points more than two decades later. Meanwhile, Evangelism keeps gaining ground in both the country and the region. While merely *** percent of Colombians were evangelical in 1996, this share had grown almost five-fold by 2020, while atheists and agnostics passed from *** to **** 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 **** and ** percent said that it helped them to quit drugs and gangs, respectively. Only *** 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.

Based on the 2020 census, Region 5 or the Bicol Region registered the highest share of households who reported Roman Catholic as their religious affiliation at 93.5 percent. This was followed by Region 8 or Eastern Visayas with a share of 92.3 percent. In contrast, only five percent of households in BARMM were Roman Catholics. The Philippines is one of the countries in the world with the highest population professing the Catholic faith, after Brazil and Mexico.

Spain has a long history of Islamic tradition under its belt. From cuisine to architecture, the southern European country has been linked to the North of Africa through many common elements. At the end of 2023, there were approximately 2.41 million Muslims in Spain, most of them of Spanish and Moroccan nationality, with upwards of eight hundred thousand believers in both cases. With a Muslim population of more than 660,000 people, Catalonia was home to the largest Muslim community in Spain as of the same date.

The not so Catholic Spain

Believers of a religion other than Catholicism accounted for approximately 3 percent of the Spanish population, according to the most recent data. Although traditionally a Catholic country, Spain saw a decline in the number of believers over the past years. Compared to previous years, when the share of believers accounted for slightly over 70 percent of the Spanish population, the Catholic community lost ground, while still being the major religion for the foreseable future.

A Catholic majority, a practicing minority

Going to mass is no longer a thing in Spain, or so it would seem when looking at the latest statistics about the matter: 50 percent of those who consider themselves Catholics almost never attend any religious service in 2024. The numbers increased until 2019, from 55.5 percent of the population never attending religious services in 2011 to 63.1 percent in 2019. The share of population that stated to be practicing believers and go to mass every Sunday and on the most important holidays accounted for only 15.5 percent.

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.

Mali is a predominantly Muslim country with 94.84 percent of the population belonging to Islam. Of that 94.84 percent, only 0.8 percent is Shi’a versus the greater majority of Sunni Muslims in the country. While most of the population is Muslim, a small minority practice other religions as well; 2.37 percent Christianity, 2.02 percent Animist, 0.04 percent Other, 0.45 percent Atheist/Agnostic, and 0.28 percent Undeclared. Of the 2.37 percent of Christians in Mali, the majority of those are Roman Catholic. The Catholic Church has six dioceses that make up less than two percent of Mali’s population. Mali is typically defined as a secular state, with a constitution and code of laws that protect the public’s right for religious freedom and practice.

While the Malian government is officially secular, it frequently consults the moderate High Council of Islam (HCIM) and the Committee of Wise Men on controversial social issues of national scope. The HCIM is an umbrella organization with representatives from all significant Muslim organizations in-country as well as over 160 non-governmental organizations. The Committee of Wise Men includes the Catholic Archbishop and prominent Malian Protestant and Muslim leaders. In an effort to enshrine its commitment to multi-faith democracy, the Malian government has declared a diverse set of religious holidays as national holidays, including Mawloud, the Prophet’s Baptism, Easter Monday, Eid al- Fitf, Tabaski, and Christmas.

Religion is not taught in any public school in Mali. There are some private schools and madrasas that do offer both Christian and Islamic teachings in addition to the state-mandated secular curriculum. In Mali, most madrasas are located in the south in areas such as Sikasso (600), Segou (428), and Bamako (268). In the northern regions of Mali there are a little over 300 madrasas.

In recent months, a loose coalition of militant Tuareg and Islamist groups, including al-Qaeda in the Islamic Maghreb (AQIM), Ansar Dine, the Movement for Unity and Jihad in West Africa (MUJAO), and the Azawad National Liberation Movement (MNLA), has taken over northern Mali with the goal of forming an Islamic state in the Trans-Sahara region. Areas under militant control have seen the imposition of strict Sharia law, including bans on music and severe restrictions on women and practitioners of non-Islamic faiths. In Timbuktu and other northern urban centers, different Islamic groups have destroyed numerous ancient Sufi mosques, tombs, and other artifacts in an effort to purge the region of “heretical” faiths.

During a survey conducted in 2023, approximately 54 percent of respondents in 17 Latin American countries claimed to be catholic. Meanwhile, 14.9 percent of the people participating in the survey said they did not profess any religion.In Mexico, more than 69 percent of respondents said they professed Catholicism.

Roughly 85 percent of Guinea’s population is Muslim, primarily of the Sunni school. Muslims constitute a majority in all four geographic regions. Christians, mostly Roman Catholic, comprise an 8 percent minority and are situated primarily in Conakry and eastern parts of the Forest Region.Other Christian denominations include Anglicans, Baptists, Jehovah's Witnesses, Seventh-Day Adventists, and various evangelical subgroups. Approximately 7 percent of inhabitants, located principally in the Forest Region, adhere exclusively to indigenous religious beliefs. Islam was introduced in Guinea in the 17th century in what is now the country’s northeast. Starting in the late 1720s, the Fulani ethnic group established a theocratic Muslim state in the mountainous Fouta Djallon region. The Fulani created an ethnoreligious social hierarchy which relegated non-Muslims to the lowest rungs of the social ladder. Though the state was ultimately assimilated into Guinea-proper, the Fulani have remained the country’s most ardent Muslim population, ahead of the Mandinka subgroup of the Mandé people. The non-Muslim Soso people were gradually pushed out of the Fouta Djallon due to Fulani oppression. The majority migrated to coastal parts of Lower Guinea between the 17th and 20thcenturies; an area comprised of the prefectures Boke, Boffa, Conakry, Coyah, Dubreka, Fria, Forecariah, Kindia, and Telimele. Roman Catholic missionaries made inroads into Soso communities following their (the Soso’s) establishment of trade ties with Europe. Many Guinean children, particularly in the Fouta Djallon region attend Islamic schools, which combine the government’s secular curriculum with Quranic studies. More devout Muslims student may enroll at a madrassah, or mosque school, which typically forego French for Arabic as the language of instruction, and adhere exclusively to a religious studies curriculum. Though Guinea’s constitution guarantees religious freedom, Islam enjoys demographic, social, and cultural dominance. In the past some Guineans have claimed the government favors Muslims in its policies, citing the cancellation of classes at publicly funded universities in accommodation of Friday prayers. Despite these and other reports of social discrimination against non-Muslims, religious freedoms are generally respected in the country.

The share for Catholic and Evangelic believers in Brazil show opposite trends. While in 1994 Catholics gathered 75 percent of the Brazilian population, it is estimated that in 2032 this figure will drop to 39.8 percent. Meanwhile Evangelicals, which at the beginning of the indicated period were only 14 percent of the population, are estimated to reach 38.6 percent by 2032, a growth of 24.6 percentage points. Nevertheless, in 2019, Brazilian catholic believers were still the largest group, with 51 percent.

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.

Kenya had a Catholic population of roughly 9.7 million people, according to the last country census conducted in 2019. Around one million Catholics lived in the capital Nairobi, the largest amount among all Kenyan counties. Nearly 590,000 people living in Kiambu adhered to Catholicism, while half-million dwelled in Machakos.

In 2024, Ethiopia had the largest Christian population in Africa, with around 77.5 million people who identified as Christian. The second highest Christian population was in Nigeria, with 74.4 million people. Christianity has a significant presence in Africa, with its history on the continent dating back to the fourth century in Ethiopia. Furthermore, Christianity has spread throughout Africa with different denominations and traditions, taking root in various regions. Some of the largest Christian denominations in Africa include the Roman Catholic Church, the Anglican Church, and the Pentecostal and Charismatic movements.

The figures for Catholic and Evangelic believers in Peru show opposite trends, according to a survey conducted in the country between 1995 and 2020. In 1995, Catholics made up for nearly 90 percent of the population, while in 2020 this figure fell to 69.4 percent. Despite it, Peru remains one of the Latin American countries with the largest share of Catholic believers. In the same time frame, the share of Evangelists grew from 3.8 to 17.5 percent.

Based on the 2020 census, the majority of Filipino households were affiliated with the Roman Catholic religion, accounting for about 79 percent. Meanwhile, the share of the Muslim population was 6.4 percent. The Philippines is one of the countries in the world with the highest population professing the Catholic faith, after Brazil and Mexico.
