Over 80,000 missionaries are serving missions for The Church of Jesus Christ of Latter-day Saints. Most are young people under the age of 25, serving in nearly 400 missions throughout the world. Missionaries can be single men between the ages of 18 and 25, single women over the age of 19 or retired couples. Missionaries work with a companion of the same gender during their mission, with the exception of couples, who work with their spouse. Single men serve missions for two years and single women serve missions for 18 months.
