WASHINGTON, Dec. 19 (UPI) -- There are 2.18 billion Christians around the world, nearly a third of the estimated 2010 global population of 6.9 billion, a demographic study found.
The comprehensive demographic study of more than 200 countries said Christians are also geographically widespread and that no single continent or region can indisputably claim to be the center of global Christianity, the Pew Research Center's Forum on Religion & Public Life reported.
