Administrative districts of South Korea

South Korea is made up of 17 first-tier administrative divisions: 6 metropolitan cities (gwangyeoksi 광역시/廣域市), 1 special city (teukbyeolsi 특별시/特別市), 1 special self-governing city (teukbyeol-jachisi 특별자치시/特別自治市), and 9 provinces (do 도/道), including one special self-governing province (teukbyeol jachido 특별자치도/特別自治道). These are further subdivided into a variety of smaller entities, including cities (si 시/市), counties (gun 군/郡), districts (gu 구/區), towns (eup 읍/邑), townships (myeon 면/面), neighborhoods (dong 동/洞) and villages (ri 리/里).

Official Revised Romanization of Korean spellings are used

The top tier of administrative divisions are the provincial-level divisions, of which there are several types: provinces (including special self-governing provinces), metropolitan cities, special cities, and special self-governing cities. The governors of the provincial-level divisions are elected every four years.

A si (시; 市, pronounced [ɕi]) is one of the divisions of a province, along with gun. Cities have a population of at least 150,000; once a county (gun) attains that population, it becomes a city (Gijang county in Busan is an exception). Cities with a population of over 500,000 (such as Suwon, Cheongju, and Jeonju) are divided into districts (gu); Gimhae, Hwaseong and Namyangju are noticeable exceptions to this rule. Gus are then further divided into neighborhoods (dong); cities with a population of less than 500,000 do not have wards – these cities are directly divided into neighborhoods (dong).
