In contrast, Latin America and the Caribbean, which was the most heavily Catholic region in 1910 and 2010, grew from 4% of the global population in 1910 to 9% in 2010. The share of the region's population that is Catholic decreased from about 90% in 1910 to 72% in 2010.
North America's share of the global Catholic population has increased slowly, from about 5% in 1910 to 8% as of 2010. The Catholic share of its population grew from 16% to 26% during this period. In 2010, there were an estimated 75.4 million Catholics in the United States, 22.2 million of whom were born outside the country. Three-quarters (76%) of Catholic immigrants in the US are from Latin America and the Caribbean, 10% from Asia-Pacific, and 10% from Europe.
In Europe, the Catholic population decreased from 44% in 1910 to 35% in 2010. The largest growth in the Catholic population as a percentage of the regional population occurred in Sub-Saharan Africa, which went from about 1% Catholic in 1910 to 21% Catholic in 2010. The Catholic share of the population in the Asia-Pacific region grew from 1% to 3% during this period.
According to the CIA Factbook and the Pew Research Center, the country with the largest percentage of Catholics in its population is Vatican City at 100%, followed by Timor-Leste at 97%.

Mexico has the second-largest Catholic population, with around 100 million or 72.1% of the population practising the religion. The Philippines is third, with 85.5 million Catholics, making up 81% of the population. This makes the Philippines the country with the largest Catholic population in Asia.
The United States has the fourth-largest Catholic population, with an estimated 69.3 million people identifying as Catholic.

Catholic population growth
The Catholic population has grown over the past century, with the number of Catholics worldwide more than tripling between 1910 and 2010. However, the growth of the Catholic population has not kept pace with the rapid rise in the overall global population during the same period. As a result, Catholics now constitute a smaller proportion of the world's population than they did in 1910, though this varies by region.
In 2010, the Catholic population was estimated to be 1,078,790,000 by the Pew Research Center, while the Vatican Publishing House's "Statistical Yearbook of the Church" placed the number at 1.196 billion. The discrepancy between these estimates and the challenges of collecting accurate data highlight the complexity of measuring religious populations.
Regional distribution plays a significant role in understanding Catholic population growth. Latin America and the Caribbean experienced substantial population growth between 1910 and 2010, increasing from 4% to 9% of the global population. As a result, despite a decline in the proportion of Catholics in the region, Latin America became the largest Catholic population in sheer numbers, surpassing Europe.
North America's share of the global Catholic population has increased more slowly, rising from 5% in 1910 to 8% in 2010. The United States is home to about 7% of the world's Catholics, with an estimated 23% of US adults identifying as Catholic in 2010. Brazil and Mexico have the largest and second-largest Catholic populations globally, respectively, although the percentage of self-identified Catholics in these countries has decreased over the last decade.
The Asia-Pacific region has witnessed rapid growth, with the number of Catholics increasing from 5% to 12% over a century. In contrast, the Middle East and North Africa, the ancient cradle of Christianity, continue to have less than 1% of the world's Catholic population, similar to a century ago. Sub-Saharan Africa has seen the largest growth in the Catholic share of its population, increasing from about 1% in 1910 to 21% in 2010.
While the number of priests is decreasing globally, the Catholic population per priest is rising, with an average of 3,373 Catholics for every priest. The Catholic Church's vast network includes educational institutions, healthcare centres, and charities, contributing to its presence and impact worldwide.

Catholic immigrants
As of 2022, it is estimated that there are 1.3 billion Catholics in the world, making Catholicism the largest Christian denomination and accounting for over half of all Christians. This number represents a significant portion of the global population and can be largely attributed to the widespread historical influence of Catholic European empires and the lasting impact of Catholic missionary work.
Among these 1.3 billion Catholics are countless immigrants who have played, and continue to play, a pivotal role in shaping Catholic communities worldwide. Catholic immigrants have a long and complex history, often fleeing religious persecution, economic hardship, or political instability in their home countries. They have sought refuge and new opportunities in regions where the Catholic Church has had a significant presence, contributing to the growth and diversification of Catholic populations.
The experiences and contributions of Catholic immigrants are diverse and varied. Many have enriched their new homes with their cultural traditions, culinary heritage, and unique devotional practices. They have established ethnic enclaves, preserving their languages and customs while also integrating into their new societies. Catholic immigrants have made significant contributions to their adopted countries in various fields, including the arts, science, education, and politics. They have also been instrumental in the development of Catholic institutions, such as schools, hospitals, and charities, which have benefited communities at large.
One notable example of the impact of Catholic immigrants can be seen in the United States. Waves of Catholic immigration from countries like Ireland, Italy, Poland, and Latin America have transformed the religious landscape of the nation. These immigrants brought with them a vibrant faith that helped shape the American Catholic Church. They established parishes, dioceses, and religious orders, and their devotion and commitment to their faith have left an indelible mark on American Catholicism.
In conclusion, Catholic immigrants represent a significant portion of the global Catholic population and have had a profound impact on the Church and their adopted societies. Their resilience, faith, and contributions have enriched Catholic communities and continue to shape the religious landscape worldwide. As the Catholic Church continues to evolve, the stories and experiences of Catholic immigrants remain integral to its diverse and vibrant character.
