A mission of The Church of Jesus Christ of Latter-day Saints is a geographical administrative area to which church missionaries are assigned. Almost all areas of the world are within the boundaries of an LDS Church mission, as of July 2015, there are 418 missions of the LDS Church. Geographically, a mission may be a city, a city and surrounding areas, typically, the name of the mission is the name of the country, and then the name of the city where the mission headquarters office is located. New missionaries receive a formal mission call, assigning them to a mission for the duration of their two years or eighteen months of service. Each mission has, on average, about 150 missionaries serving there, see main article, Mission president All missionaries serve in a mission under the direction of a mission president, who, like individual missionaries, is assigned by the LDS Church president. The mission president must be a high priest in the Melchizedek Priesthood. In 2013 the mission presidents wife was given leadership roles in the mission. Mission presidents are typically in their forties or older, and usually have the means to devote themselves full-time to the responsibility for three consecutive years. The church provides mission presidents with a living allowance but it normally requires them to supplement it with their own funds. Often, the president must learn the local language spoken in the mission. The mission president has at least two counselors, who are Latter-day Saints usually from the area who keep their regular employment. The role of the counselors varies by mission, but they serve as liaisons between the mission and the local membership of the church. In some areas where the church is newer senior men who are serving full-time missions along with their wives may be called as counselors in the mission presidency, like other units of the church, a leadership council is used to assist in governance of the mission. Prior to April 2013, this was called a zone leader council, consisting of the mission president, assistants to the mission president. Missions are organized in two parallel structures, the first is the organization of the missionaries. There are two or more missionaries who serve as assistants to the president, the missionaries are divided into zones, each led by one or more missionaries assigned as zone leaders. The zones may be large or small depending on the mission. The number of missionaries in a zone also varies widely, the zones are divided into districts, each being led by a missionary assigned as a district leader
