List of districts of Seoul
The Districts of Seoul are the twenty-five "gu" ("districts"; hangeul: 구; hanja: 區) comprising Seoul, South Korea. The "gu" vary greatly in area (from 10 to 47 km) and population (from less than 140,000 to 630,000). Songpa-gu is the most populated, while Seocho-gu has the largest area. Gu are similar to London's or New York's boroughs or Tokyo's 23 special wards. Each gu's government handles many of the functions that are handled by city governments in other jurisdictions. This city-like standing is underscored by the fact that  each gu has its own legislative council, mayor and sister cities. Each "gu" is further divided into "dong" or neighborhoods. Some "gu" have only a few "dong" while others (like Jongno-gu) have a very large number of distinct neighborhoods. List by population and area. "2014 estimate by Seoul Statistics".
