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.

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.

Except for Uruguay, over 60 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 82.8 to 33.4 percent.

In 2022, there were around 1.39 billion Catholics worldwide, approximately 17.7 percent of the total global population. Even though the Catholic population has increased in absolute numbers, the share of Catholics has always fluctuated around 17 percent since 2010.

In 2022, there were around 1.39 billion Catholics worldwide, compared to 1.38 billion in 2021. In more than 20 years, the global Catholic population grew by approximately 194 million people. The Catholic population is growing fast in Africa and in the Americas, while it is declining in Europe.

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.

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.

This statistic shows the total population of Brazil from 2020 to 2023, with a forecast through 2030. In 2023, the total population of Brazil was estimated at around 211.7 million inhabitants. Population of Brazil Brazil has a surprisingly low (and decreasing) population growth rate; despite it being home to the largest number of Catholics in the world, the majority of women in Brazil use some form of contraception, which is often government-subsidized or free, even though the Catholic Church retains its stance that the use of contraceptives is inherently wrong. Within the space of just one generation, families have gone from having more than six children to having just one or two, and the share of Catholics in the population is dwindling, too. The influence of 'telenovelas' — the overwhelmingly popular soap operas often with strong women figures and fewer than three children — could also be helping shape the population’s view of what an ideal family is. The fertility rate in Brazil fell below the replacement rate in 2006 and is still decreasing. The impending population imbalance in Brazil can be seen in the decreasing lower tier of the country’s age distribution. This follows a trend similar to the one Japan and many European countries are experiencing, which are now facing the problems of providing for an aging population with fewer young and working taxpayers. The trend is not quite as extreme in Brazil, giving it time to prepare for the fallout of decreasing family size. This preparation will be important to help the country maintain its emerging economic strength, which is watched with interest by many economists who have said that Brazil’s is one to watch — thus its position as one of the pillars of the “big four” BRIC countries.

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.

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.
