A new report on religion and international migration by the Pew Research Center’s Forum on Religion & Public Life finds that Christians comprise nearly half – an estimated 106 million, or 49% – of the world’s 214 million international migrants. According to the study, Faith on the Move: The Religious Affiliation of International Migrants, Muslims make up the second-largest group – almost 60 million, or 27%. The remaining quarter are a mix of Hindus, Buddhists, Jews, adherents of other faiths and the religiously unaffiliated (those who identify as atheists and agnostics or say they have no particular religion).

Atheists and agnostics, Jews and Mormons are among the highest-scoring groups on a new survey of religious knowledge by the Pew Research Center’s Forum on Religion & Public Life, outperforming evangelical Protestants, mainline Protestants and Catholics on questions about the core teachings, history and leading figures of major world religions.

By some key measures, Americans ages 18 to 29 are considerably less religious than older Americans, according to a new report released by the Pew Research Center's Forum on Religion & Public Life.

A new survey finds that Americans change their religious affiliation early and often, and the reasons they give for changing—or leaving religion altogether—differ widely depending on the origin and destination of the convert.

"Faith in Flux: Changes in Religious Affiliation in the U.S." is a follow-up to the U.S. Religious Landscape Survey, conducted by the Pew Forum in 2007 and released in 2008, which found that a remarkably high number of people have changed their religious affiliation since childhood.
