South Korea is made up of 17 first-tier administrative divisions,6 metropolitan cities,1 special city,1 special self-governing city, and 9 provinces, including one special self-governing province. These are further subdivided into a variety of entities, including cities, counties, districts, towns, townships, neighborhoods and villages. The governors of the divisions are elected every four years. A si is one of the divisions of a province, along with gun, cities have a population of at least 150,000, once a county attains that population, it becomes a city. Cities with a population of over 500,000 are divided into districts, Gimhae, Hwaseong, gus are then further divided into neighborhoods, cities with a population of less than 500,000 do not have wards – these cities are directly divided into neighborhoods. A gun is one of the divisions of a province, and of the cities of Busan, Daegu, Incheon. A gun has a population of less than 150,000, is densely populated than a gu. Gun are comparable to British non-metropolitan districts, counties are divided into towns and districts. Specially, the size of a gun is less than a US county, a gu is equivalent to district in the West. Most cities are divided into gu, though the cities of Busan, Daegu, Incheon. Gu are similar to boroughs in some Western countries, and a gu office handles many of the functions that would be handled by the city in other jurisdictions, an eup is similar to the unit of town. Along with myeon, an eup is one of the divisions of a county, the main town or towns in a county—or the secondary town or towns within a citys territory—are designated as eup. In order to form an eup, the population required is 20,000. A myeon is one of the divisions – along with eup – of a county, myeons have smaller populations than eup and represent the rural areas of a county or city. The minimum population limit is 6,000, a dong is the primary division of districts, and of those cities which are not divided into districts. The dong is the smallest level of government to have its own office. In some cases, a legal dong is divided into several administrative dong. Administrative dong are usually distinguished from one another by number, in such cases, each administrative dong has its own office and staff
