Though you might not know it from Broadway's "The Book of Mormon," 12% of Mormon missionaries are women—a number that is about to skyrocket thanks to an unexpected change in official Latter-day Saint policy. The church announced last month that Mormon women are now eligible to begin serving missions at age 19 instead of 21, and that Mormon men may serve at 18 instead of 19.
It has been quite a year for Mormonism in America. Outside the faith, the presidential candidacy of Mitt Romney sparked unprecedented levels of interest and attention. Meanwhile, church leaders have transformed how young Mormons start their adulthood, affecting everything from education to dating and marriage.
