How many Catholics live in the world today, and where can they be found? As of June 2023, the global Catholic population reached 1.406 billion people, representing 17.8% of the world’s total population. This marks an increase of 15.881 million Catholics compared to 2022, reflecting a steady growth rate of 1.15% and demonstrating the Church’s continued expansion across nearly 39.6% of global territories. Scholars use linguistic, historical, and textual criticism to date texts and examine the canonization process.
The global Catholic community encompasses 1.406 billion faithful across nearly two-fifths of the world’s territories as of 2023.
The distribution of Catholics varies markedly across continents, with the Americas holding the largest share at 47.8% of the world’s Catholic population. South America alone accounts for 27.4% of all Catholics globally. Africa represents 20% of the Catholic community and shows the most energetic growth at 3.31%.
Meanwhile, Europe hosts 20.4% despite experiencing minimal growth of just 0.2%. Asia and Oceania together make up the remaining percentage, displaying varied regional patterns.
Brazil leads all nations with 182 million Catholics, comprising 13% of the global Catholic population. In Africa, the Democratic Republic of Congo stands first with 55 million Catholics, followed by Nigeria’s 35 million. Uganda, Tanzania, and Kenya also maintain substantial Catholic communities in East Africa.
Additionally, Argentina and Spain represent major Catholic populations in their respective regions. The 2025 Pontifical Yearbook provides comprehensive data and insights into these worldwide Catholic demographics and activities.
Some countries demonstrate remarkably high Catholic percentages among their residents. Vatican City maintains 100% Catholic population, while Timor-Leste reports 97.57% and San Marino registers 97%. Italy, Poland, and Spain each exceed 90% Catholic incidence, reflecting deep historical and cultural connections to the faith.
Despite population growth, the Church faces challenges in religious vocations. Priest numbers declined by 734 globally, while women religious decreased by 9,805. Notable declines are occurring in Europe and the Americas.
Europe shows a -4.9% decrease in religious vocations, Asia registers -4.2%, and the Americas demonstrate -1.3%. The Church operates extensive educational institutions including 74,550 kindergartens, 102,455 primary schools, and 52,085 secondary schools worldwide.
Looking ahead, Africa appears positioned to propel future Catholic growth given current demographic trends, while Europe’s stagnant population dynamics may limit expansion. The Vatican’s Central Office of Church Statistics continues monitoring these developments, with the most recent all-encompassing data extending through June 2023.
