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. 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.2 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%). Read the full

Distribution of the World's Christian Population,
