Ex-Mormon or post-Mormon refers to a disaffiliate of the Church of Jesus Christ of Latter-day Saints (LDS Church) or any related groups, such as the Community of Christ (formerly the Reorganized Church of Jesus Christ of Latter Day Saints or the RLDS church), The Church of Jesus Christ (or the Bickertonites), and in rare cases the Fundamentalist Church of Jesus Christ of Latter-day saints (FLDS Church), all of which are 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.
