Administrative divisions of South Korea

[1][2] 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).

A gun (군; 郡) is one of the divisions of a province (along with si), and of the metropolitan cities of Busan, Daegu, Incheon and Ulsan (along with gu).

A myeon (면; 面) is one of the divisions – along with eup – of a county (gun) and some cities (si) of fewer than 500,000 population.

Myeons have smaller populations than eups and represent the rural areas of a county or city.

[6] Some populous dong are subdivided into ga (가; 街), which are not a separate level of government, but only exist for use in addresses.

Many major thoroughfares in Seoul, Suwon, and other cities are also subdivided into ga.[7] A ri (리; 里) is the only division of towns (eup) and townships (myeon).

[8] Although the details of local administration have changed over time, the basic outline of the current three-tiered system was implemented under the reign of Gojong in 1895.
