Study Shows Mormonism is Fastest-Growing Faith in Half of U.S. States

Mitt Romney may or may not become the first Mormon to move into the White House next year, but a new study shows that Mormonism is moving into more parts of the country than any other religious group, making it the fastest-growing faith in more than half of U.S. states.

The 2012 Religious Congregations and Membership Study, released here Tuesday (May 1), shows that the mainline Protestants and Catholics who dominated the 20th century are literally losing ground to the rapid rise of Mormons and, increasingly, Muslims.
