Christianity
As a percentage of Christians, the Catholic Church and Orthodoxy (both Eastern and Oriental) are declining in parts of the world (though Catholicism is growing in Asia, in Africa, vibrant in Eastern Europe, etc.), while Protestants and other Christians are on the rise in the developing world. The so-called "popular Protestantism" is one of the fastest growing religious categories in the world. Nevertheless, Catholicism will also continue to grow to 1.63 billion by 2050, according to Todd Johnson of the Center for the Study of Global Christianity. Africa alone, by 2015, will be home to 230 million African Catholics. And if in 2018 the U.N. projects that Africa's population will reach 4.5 billion by 2100 (not 2 billion as predicted in 2004), Catholicism will indeed grow as will other religious groups.
