Global Catholic population in 2025: 1.4 billion
The Catholic Church, comprising the Latin Church and 23 Eastern Catholic Churches, is the oldest continuously functioning international institution in the world. It is also the largest non-government provider of education and healthcare globally. As of 2025, the global Catholic population is estimated to be 1.4 billion. This number represents a notable 1.15% increase from 2022, when there were approximately 1.39 billion Catholics worldwide.
The Americas continue to be the region with the highest proportion of Catholics, accounting for 47.8% of the global total. Brazil has the largest number of Catholics in the Americas, with 182 million, while Argentina, Colombia, and Paraguay have Catholic populations exceeding 90%. In South America, 27.4% of Catholics in the Americas reside, while 6.6% are in North America, and 13.8% in Central America.
In Asia, the Catholic population grew by 0.6% between 2022 and 2023, with the Philippines and India registering significant numbers. The Catholic population in Oceania also experienced an increase of 1.9%, totaling just over 11 million Catholics in 2023.
Africa registered the greatest growth in the Catholic population, increasing by 3.31% from 2022 to 2023. This growth is particularly evident in countries such as the Democratic Republic of Congo, Nigeria, Uganda, Tanzania, and Kenya.
While the Middle East and North Africa are the ancient cradle of Christianity, the region currently represents less than 1% of the global Catholic population.

Catholic population growth: 1.15% increase between 2022 and 2023
According to the Vatican's Central Office of Church Statistics, the global Catholic population increased by 1.15% between 2022 and 2023. This marks a notable rise from approximately 1.39 billion to 1.406 billion adherents worldwide. The distribution of baptised Catholics differs across various geographic areas, influenced by the distinct demographic characteristics of each continent.
The Catholic Church, the world's oldest continuously functioning international institution, has experienced dynamic shifts in its regional distribution over the past century. In 1910, Europe was the epicentre of Catholicism, housing about two-thirds of all Catholics, with nearly nine-tenths residing in Europe (65%) and Latin America (24%). However, by 2010, Europe's share had significantly diminished to 24% of the global Catholic population.
Latin America and the Caribbean witnessed a substantial population growth during this period, increasing from 4% of the global population in 1910 to 9% in 2010. This shift altered the religious landscape, with Latin America surpassing Europe as the region with the largest Catholic population.
The latest statistics from the Vatican underscore the evolving nature of the Catholic Church's global presence. While the relative weight of each continent has largely remained stable, there are notable variations in the number of Catholics per bishop across regions. For instance, Africa and America present higher figures, with 365,000 and 334,000 Catholics per bishop, respectively. Oceania enjoys a favourable situation, with each bishop catering to 87,000 Catholics, indicating a slight excess of bishops compared to other continents.
In terms of ecclesiastical jurisdictions, the Catholic world encompasses 3,041 jurisdictions as of the end of 2023. The number of priests within these jurisdictions totalled 406,996, reflecting a marginal decrease of 734 from the previous year. These statistics shed light on the organisational structure and human resources of the Catholic Church, highlighting potential imbalances between the demand and supply of pastoral services.

Catholic population by region: 47.8% in Americas, 20.4% in Europe, 27.4% in South America
The Catholic Church is the largest non-government provider of education and healthcare in the world. According to the 2023 Annuario Pontificio (Pontifical Yearbook), the number of baptized Catholics in the world was about 1.376 billion at the end of 2021. However, the World Christian Database estimates the number of Catholics worldwide as of 2025 to be 1.272 billion. Another source estimates the global Catholic population in 2025 to be 1.4 billion, with a growth of 1.15% between 2022 and 2023.
The Americas have the highest proportion of Catholics in the world, with 47.8% of the global total. South America alone accounts for 27.4% of the global Catholic population, with Brazil having the largest number of Catholics in the region, at 182 million. This represents 13% of the world's total Catholic population. Argentina, Colombia, and Paraguay also stand out in South America, with over 90% of their populations identifying as Catholic. North America and Central America, on the other hand, account for 6.6% and 13.8% of the global Catholic population, respectively.
Europe, which was once home to about two-thirds of the world's Catholics, now accounts for a much smaller proportion. As of 2025, Europe is home to 20.4% of the world's Catholics. This decline is partly due to the overall population growth in other regions, such as Latin America and the Caribbean, which grew from 4% of the global population in 1910 to 9% in 2010.
Africa has also experienced significant growth in its Catholic population, with about 171 million Catholics (16%) in sub-Saharan Africa alone, up from an estimated 1 million (less than 1%) in 1910. The Democratic Republic of Congo leads the region with nearly 55 million Catholics, followed by Nigeria with 35 million. Africa currently represents 20% of the world's Catholic population.

Catholic immigrants in the US: 76% from Latin America
The Catholic Church is the world's oldest continuously functioning international institution, and the largest non-government provider of education and healthcare globally. As of 2025, there are 1.4 billion Catholics worldwide, constituting 48.1% of 2.6 billion Christians. The global Catholic population increased by 1.15% between 2022 and 2023.
The number of Catholics in the world has tripled over the past century, but the overall population has also increased rapidly, so Catholics have maintained a stable share of the global population. However, the geographic distribution of Catholics has changed substantially. In 1910, Europe was home to two-thirds of all Catholics, and 90% lived in Europe or Latin America. By 2010, only a quarter of Catholics lived in Europe, while 39% lived in Latin America and the Caribbean.
In the US, Catholicism is the single largest religious group, with 62 million adherents. The percentage of Americans who are Catholic has fallen from 25% in 1960 to 22% in 2021. Three-quarters (76%) of Catholic immigrants in the US are from Latin America and the Caribbean, with 10% from Asia-Pacific and 10% from Europe. The Catholic Church in the US is highly diverse, with most dioceses offering Mass in multiple languages. The growth in the US Catholic population is partly due to immigration from Latin America, with nearly half of foreign-born US Catholics coming from this region. The US Catholic population has also been boosted by relatively high fertility rates among Latino women. In 2021, 33% of adult Catholics were Hispanic, and 45% of Catholics aged 18-29 were Hispanic/Latino.
