Catholics Worldwide

The Roman Catholic flock has quadrupled from an estimated 291 million faithful in 1910 to 1.2 billion a century later. As a share of the global population, Catholics have remained steady at about 17 percent, but their geographic range has changed dramatically. In 1910, two-thirds of the world’s Catholics lived in Europe; now less than a quarter do.
