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 ** 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.

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.

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.

In 2020, Mexico had a catholic population of ********** people, by far the most followed religion in the country. Almost ** 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.

Based on the 2020 census, the majority of Filipino households were affiliated with the Roman Catholic religion, numbering about 86 million people. Meanwhile, there were roughly seven million Muslims in the country. The Philippines is one of the countries in the world with the highest population professing the Catholic faith, after Brazil and Mexico.

As of 2015, around ** million female and male population among households in the Philippines were affiliated with the Roman Catholic Church. The Philippines is one of the countries in the world with the highest population professing the Catholic faith, after Brazil and Mexico.

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.

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. Around ** percent considered themselves not very observant, while around a third classified as somewhat observant.

Roman Catholic was the most common religion affiliation in Mexico in 2023. In a survey carried out that year, roughly **** percent of Mexican respondents claimed to be of catholic faith. Mexico ranks among the Latin American countries with the highest share of Catholics. More than nine percent of respondents answered they didn't profess any religion.

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.

This statistic shows the ten largest cities in Italy in 2025. In 2025, around 2.75 million people lived in Rome, making it the largest city in Italy. Population of Italy Italy has high population figures and a high population density in comparison to other European countries. A vast majority of Italians lives in urban areas and in the metropolises (as can be seen in this statistic), while other areas, such as the island Sardinia, are rather sparsely inhabited. After an increase a few years ago, Italy’s fertility rate, i.e. the average amount of children born to a woman of childbearing age, is now on a slow decline; however, it is still high enough to offset any significant effect the decrease might have on the country’s number of inhabitants. The median age of Italy’s population has been increasing rapidly over the past 50 years – which mirrors a lower mortality rate – and Italy is now among the countries with the highest life expectancy worldwide, only surpassed by two Asian countries, namely Japan and Hong Kong. Currently, the average life expectancy at birth in Italy is at about 83 years. Most of Italy’s population is of Roman Catholic faith. The country actually boasts one of the largest numbers of Catholics worldwide; other such countries include Brazil, Mexico and the United States. The central government of the Roman Catholic Church, the Holy See, is located in Vatican City in the heart of Italy’s capital and ruled by the Bishop of Rome, the Pope. Officially, Vatican City does not belong to Italy, but is a sovereign state with its own legislation and jurisdiction. It has about 600 inhabitants, who are almost exclusively members of the clergy or government officials.

BackgroundThe northeastern region of Argentina has the highest age-adjusted cervical cancer mortality rates. Given the strong link between HPV infections and cervical cancer, one of the main interventions is the population-based use of HPV vaccines. However, the acceptability is not very clear in low- and middle-income countries. The purpose of this study was to estimate the level of HPV vaccine acceptance and associated determinants among caregivers of girls in a northeastern city of Argentina.MethodsA school-based survey was conducted in 2015 using a multistage sampling method. The primary sample unit were schools stratified by socioeconomic status selected at random, and caregivers of school girls were interviewed. The acceptability was determined using the adapted Theory of Planned Behavior. We performed logistic regression models to assess associated determinants.ResultsThe study included 347 caregivers. The intention to vaccinate was 59.88%. A positive attitude of caregivers (aOR 4.67; 3.11–7.03) and positive influence of social norms (aOR 1.95; 1.03–3.70) were the main predictors independently associated to the intention to vaccinate against HPV. In contrast, practicing a Christian non-Catholic religion decreased the intention to vaccinate against HPV (OR 0.59; 0.36–0.95). All other factors evaluated were not significantly associated with intention to vaccinate against HPV.ConclusionsThis study shows that evaluating attitudes, normative social beliefs, and perceived self-efficacy regarding HPV vaccination can be of utmost importance for mapping and planning of health-related strategies in developing countries.

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. Particularly in Honduras, Colombia and Ecuador, most Christians think religion is very important in their lives.

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.
