The next article also shows that there is 33% share of Christians in
world population but also mentions other very interesting figures as
well.

“Almost two billion Christians live on every continent. They comprise
the majority of people living in the United States and Canada (86%),
Latin America (92%), Europe (76%) and Australia (85%). Christianity is
also the most prevalent faith in Africa (48%). Christianity is a
dominant force on every continent but Asia (9%). Most of the world's
population is in Asia, so only one-third of the world's population is
Christian.”

“About half of the world's Christian population is Roman Catholic.”
