Ex-Mormon or post-Mormon refers to a disaffiliate of the Church of Jesus Christ of Latter-day Saints (LDS Church) or any of its schismatic breakoffs, collectively called "Mormonism". Ex-Mormons—sometimes referred to as exmo or postmo[1]—may neither believe in nor affiliate with the LDS Church. In contrast, Jack Mormons may believe but do not affiliate; and cultural Mormons may or may not affiliate but do not believe in certain doctrines or practices of the LDS Church. The distinction is important to a large segment of ex-Mormons, many of whom consider their decision to leave as morally compelling and socially risky. According to 2014 Pew data, around 1/3 of adults raised LDS no longer adhere to the faith (up from around 10% in the 1970s and 1980s) and in 2008 only 25% of LDS young adults were actively involved.[2][3] Two surveys taken across the state of Utah between 1980 and 1981, showed that for every five converts into Mormonism, there were two converts out.[4] Many ex-Mormons experience troubles with family members who still follow Mormon teachings.[5] Aggregations of ex-Mormons may comprise a social movement.
