“Global Christianity: A Report on the Size and Distribution of the World’s Christian Population” has just been published by the Pew Research Center’s Forum on Religion & Public Life. The report locates Christian populations around the world and compares them with other religious groups and with historical estimates of the number of Christians from a century ago.

Using data from the report, I have put together the following simple quiz so you can test your own knowledge.

I will post the answers on this blog tomorrow, or you can look up the answers yourself by reading the Pew study online.
