What You'll Learn
Catholic population in the Americas
Catholicism is a division of Christianity, the largest religion globally. The Catholic Church is the world's oldest continuously functioning international institution. It is also the largest non-government provider of education and healthcare in the world.
The Americas have a significant Catholic population, with the United States, Brazil, and Mexico having the highest numbers of Catholics in the Western Hemisphere. The United States is home to about 7% of the world's Catholics. According to a 2020 survey, there were 61.9 million Catholics in the U.S., about 18.7% of the population. However, other sources state that 20% of U.S. adults identify as Catholics, which would amount to roughly 53 million Catholic adults nationwide. The U.S. Catholic population has undergone demographic shifts, with a notable presence of Hispanic Catholics, who make up 36% of the Catholic population in the country. The average number of adherents per congregation is 3,000 for Catholics, which is unusually high compared to other groups.
Brazil has the largest Catholic population in the world, with estimates ranging from 123 million to 140 million or higher. However, the percentage of the population that identifies as Catholic has declined over time, dropping from approximately 74% in 2000 to about 65% in 2010. The CIA Factbook and the Pew Research Center report a higher percentage of 68.6% and 64.63%, respectively.
Mexico has the second-largest Catholic population globally, with an estimated 85% of the population identifying as Catholic in 2010, according to the 2010 Mexican Census. The CIA World Factbook reports an even higher percentage of 91.89%.
In Canada, the Catholic population is smaller compared to the United States, Mexico, and Brazil. In 2011, there were 12.7 million Catholics in Canada, making up 39% of the total population.
The Catholic Church has had a significant impact on the history and culture of the Americas. The Louisiana Purchase in 1803, which transferred vast territories from the French Republic to the United States, included areas with a culturally French and Catholic population. These areas, including Arkansas, Iowa, Missouri, Kansas, and Louisiana, were influenced by their Catholic heritage, as seen in the naming of settlements after Catholic saints, such as St. Louis and St. Ignace. The descendants of this colony are known today as the Louisiana Creole and Cajun people.

Catholic population in Europe
Catholicism is a division of Christianity, the largest religion in the world. The Catholic Church is the world's oldest continuously functioning international institution. It is also the largest non-government provider of education and healthcare globally.
Christianity has been practised in Europe since the first century, and a number of Pauline Epistles were addressed to Christians living in Greece and other parts of the Roman Empire. In the High Middle Ages, the Scholastic movement sought to connect Catholicism with Greek thought. The East-West Schism of the 11th century and the Protestant Reformation of the 16th century divided "Christendom" into hostile factions. The Age of Enlightenment of the 18th century brought about a rise in atheism and agnosticism in Western Europe.
In 1910, Europe was home to about two-thirds of the world's Catholics, and 44% of Europe's population was Catholic. By 2010, Europe's Catholic population had dropped to 35%, and only 11% of the world's population lived in Europe. Despite these shifts, Latin America and Europe remained the most heavily Catholic regions in the world in 2010.
According to a 2010 study by the Pew Research Center, 76.2% of the European population identified as Christian, with Roman Catholics being the largest Christian group, accounting for more than 48% of European Christians. The second-largest group were the Orthodox Christians, who made up 32% of European Christians. About 19% of European Christians were part of the mainline Protestant tradition.
European countries with significant or majority Catholic populations include Andorra, Austria, Belarus (western), Belgium, Bosnia and Herzegovina (central and southwestern), Croatia, France, Germany (western and southern), Hungary, the Republic of Ireland, Italy, Latvia (the Latgale region), Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, the Netherlands (eastern and southern), Poland, Portugal, San Marino, Slovakia, Slovenia, Spain, Switzerland (central and southern), Ukraine (western), and Vatican City. There is also a large Catholic minority in Albania (10-15%). In the Czech Republic and the United Kingdom, Catholics make up about 10% of the population, while in Serbia and Romania, they constitute over 5% of the population.
In some European countries, the number of people who do not identify with any religious faith has been increasing. For example, in the Netherlands, this number increased from 45% to 57% between 2010 and 2021. Similarly, in Sweden, the share of the population who were members of the church decreased from 69% to 54% during the same period. In France, the share of people not believing in God rose from 44% to 56% in the last 19 years.

Catholic population in Africa
Catholicism is a division of Christianity, the largest religion globally. Basic Catholic beliefs include the idea that Jesus is the son of God, that he rose from the dead, and that the Bible is the word of God.
Christian activity in Africa began in the 1st century when the Patriarchate of Alexandria in Egypt was formed as one of the four original Patriarchs of the East. However, the Islamic conquest in the 7th century resulted in a harsh decline for Christianity in Northern Africa. Despite this, there is evidence that Christianity persisted in the region for several centuries after the conquest.
In the modern era, the presence of the Catholic Church has grown in Africa, partly due to the French colonization of several African countries. Catholic Church membership rose from 2 million in 1900 to 140 million in 2000. In 2005, the Catholic Church in Africa, including Eastern Catholic Churches, embraced approximately 135 million of the 809 million people in Africa. By 2009, when Pope Benedict XVI visited Africa, it was estimated at 158 million.
Africa has added the greatest number of Catholics in recent years out of all the continents. In 2021, the African continent gained 40 million people, 8.3 million of whom were Catholic. The Democratic Republic of Congo has the highest number of baptized Catholics in Africa, with almost 55 million, followed by Nigeria with 35 million. By 2025, one-sixth of the world's Catholics (230 million) are expected to be Africans.
Africa has the largest total number of infant pupils, Catholic primary schools, primary school pupils, and Catholic secondary schools, and the third-most secondary school students out of all the continents. Africa also has a far higher rate of Mass attendance in countries with large Catholic populations. Nigeria, Kenya, and Lebanon have the highest proportion of Catholics who attend Mass weekly or more, with Nigeria as the clear leader at 94%.

Catholic population in Asia
Catholicism is a division of Christianity, the largest religion in the world. Catholics believe that Jesus is the son of God, that he was crucified around 33 CE, and that he rose from the dead and ascended to Heaven. They also believe in the Bible as the word of God, the Ten Commandments as a moral compass, and the story of Adam and Eve, including the concept of original sin.
While the number of Catholics worldwide has more than tripled over the past century, from 291 million in 1910 to 1.1 billion in 2010, the geographic distribution of Catholics has changed significantly. In 1910, Europe was home to about two-thirds of all Catholics, with nearly nine-tenths living in Europe (65%) or Latin America (24%). By 2010, Europe's share had dropped to 11% of the world's population, while Latin America and the Caribbean had grown to 9%.
Brazil has the largest Catholic population in the world, with estimates ranging from 123 million to 140 million or more. Mexico is second, with 83.9% of its population identifying as Catholic in the 2010 Mexican Census. The United States is home to about 7% of the world's Catholics, with an estimated 23-24% of the country's population being Catholic as of 2010.
In Asia, the Catholic population is much smaller, with Catholics making up less than 1% of the population in China and Japan, and less than 1.5% in India. The Philippines has a significant Catholic population, with about 80% of its 116 million people being Catholic. However, this percentage has decreased over time, and it was once believed to be the most Catholic country in Asia until the 1990s. Today, Timor-Leste has the highest percentage of Catholics in Asia, with 97-98% of its 1.5 million residents practicing the religion. Catholicism in Timor-Leste is not simply a byproduct of Western colonization, as less than 20% of the population was Catholic when Portugal left in 1975. It was during the brutal Indonesian colonization from 1975 to 1999 that the Timorese became predominantly Catholic.
Despite the relatively small percentage of Catholics in Asia, the continent is home to over 4 billion people, making it the most populous continent. Asian Catholics account for nearly 11% of all baptized members of the Universal Church, and they have built numerous educational and medical institutions across the region that play a crucial role in local societies and politics. Pope Francis has shown a focused interest in Asia, visiting several countries in recent years, including the Philippines, Thailand, Japan, and Vietnam.

Catholic population in Oceania
Oceania is predominantly Christian, with varying rates of Catholicism across the region. By 2000, the overall Catholic population in Oceania was estimated to be around 29%-30%. However, this percentage varies across the region, with countries and territories like Papua New Guinea, the Solomon Islands, and Kiribati having high rates of Catholicism, while others like Australia, New Zealand, and Fiji have more modest rates.
In the case of Papua New Guinea, which gained independence in 1975, the Catholic Church has played a significant role in the country's history. By 2000, the region had four archdioceses: Manang, Mount Hagen, Port Moresby, and Rabaul, overseeing 374 parishes. The population of Papua New Guinea was estimated to be around 4,926,984, with approximately 30% identifying as Catholic.
Tonga, on the other hand, has a different story. In the mid-19th century, Catholics faced a dangerous environment due to the intermittent wars waged by Taufaahau, a Protestant who considered Catholics his enemies. It was French intervention that ensured some tolerance for Catholics. By 2000, Tonga's population of 102,320 was 16% Catholic, organised into 12 parishes.
French Polynesia, another territory in Oceania, has a significant Catholic population as well. Approximately 33% of the population is Catholic, while 49% are Protestant, showcasing the diversity of Christian denominations in the region.
While Oceania as a whole has a significant Catholic population, it is worth noting that the region did not experience the same growth as other parts of the world between 2022 and 2023. The number of Catholics in Oceania rose by about 123,000 during this period, reaching nearly 11.11 million. However, the number of priests in the region decreased, contributing to a lower ratio of priests to Catholics compared to other regions.
