Among Christians globally, Orthodox share falling, Catholic, Protestant shares increasing % of world Christians who are Christian
Orthodox Christians have decreased as a share of the overall Christian population even as their numbers have more than doubled since 1910, when there were 125 million of them. This decrease in share is due to the fact that the worldwide populations of Catholics, Protestants and other Christians have collectively almost quadrupled over the last century (from 490 million in 1910 to 1.9 billion in 2010). Roughly one-in-eight Christians (12%) are now Orthodox, down from one-in-five (20%) in 1910.
