Pew Forum het pas ‘n uitvoerige studie gedoen oor die omvang en verspreiding van die Christendom en die vergelyking met ander gelowe.
A century ago, this was not the case. In 1910, about two-thirds of the world’s Christians lived in Europe, where the bulk of Christians had been for a millennium, according to historical estimates by the Center for the Study of Global Christianity. Today, only about a quarter of all Christians live in Europe (26%). A plurality – more than a third – now are in the Americas (37%). About one in every four Christians lives in sub-Saharan Africa (24%), and about one-in-eight is found in Asia and the Pacific (13%).
