Growth of religion
According to Harvard University professor Robert D. Putnam, an increasing number of Americans are leaving their faith and becoming unaffiliated. By 2050, Christianity is expected to remain the majority in the United states (66.4%, down from 78.3% in 2010), and the number of Christians in absolute number is expected to grow from 243 million to 262 million.
According to a 2005 paper submitted to a meeting of the American Political Science Association, most of Christianity's growth has occurred in non-Western countries. The paper concludes that the Pentecostalism movement is the fastest-growing religion worldwide. Protestantism is growing as a result of historic missionary activity and indigenous Christian movements by Africans in Africa, and due primarily to conversion in Asia, Latin America, Muslim world, and Oceania. According to Pew Research Center, Christianity is declining in the United states while non-Christian faiths are growing.
