(AP) - A new analysis spells out how the Christian population is shrinking in Europe, while growing dramatically in Africa and elsewhere.

Europe is now home to about a quarter of the world's Christians, compared to two-thirds a century ago. About one-quarter of the Christian population is now found in sub-Saharan Africa. More than a third is in the Americas.

Overall, Christians remain the largest religious group in the world, with nearly 2.2 billion people. Muslims are the second-largest group, with about 1.5 billion adherents.

The smallest concentration of Christians is found in the region where the faith began, the Mideast and North Africa, where Christians are only about 4 percent of the population.

The study was released Monday by the Pew Research Center's Forum on Religion & Public Life.
