The Pew Research Center’s Forum on Religion & Public Life has recently published a new study on global Christianity:

A comprehensive demographic study of more than 200 countries finds that there are 2.18 billion Christians of all ages around the world, representing nearly a third of the estimated 2010 global population of 6.9 billion. Christians are also geographically widespread – so far-flung, in fact, that no single continent or region can indisputably claim to be the center of global Christianity.

In the following video, Conrad Hackett, a demographer with the Pew Research Center, talks with the Wall Street Journal regarding the findings of the study.

To test your own knowledge of Christianity around the world, please take Pew Forum’s short quiz. The full analysis, “Global Christianity: A Report on the Size and Distribution of the World’s Christian Population,” is available on the their website.
