Washington, DC - 04/27/2009 - A new survey by the Pew Research Center's Forum on Religion & Public Life 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, and is based on over 2,800 callback interviews with members of the largest segments of the population that have changed religious affiliation.

The poll results offer a fuller picture of the "churn" within religion in America, where about half of adults have changed religious affiliation at least once in their life.

Key findings include:

  • Most people who change their religion leave their childhood faith before age 24, and many of those who change religion do so more than once.
  • Many people who have left a religion to become unaffiliated, the group that has grown the most from religious switching, say they did so in part because they stopped believing in the teachings of their childhood faith. Many also cite disillusionment with religious people and institutions as reasons for becoming unaffiliated.
  • Many people who have left the Catholic Church say they did so because they stopped believing in Catholic teachings. This is true for half of Catholics who have become Protestant as well as two-thirds of Catholics who have become unaffiliated. Many fewer say they left because of the clergy sexual abuse scandal.
  • In contrast with other groups, Americans who have switched from one Protestant denominational family (e.g., Baptist, Methodist) to another tend to do so because of changes in life circumstances, such as marriage or moving to a new community.
The report, including a detailed executive summary, methodology and topline questionnaire, is available on the Pew Forum's Web site. For the original "U.S. Religious Landscape Survey," visit http://religions.pewforum.org.
