Seoul Gwanak-gu is densely populated where 513,186 people living in the area of 29.57 km², based on the Korean Republic Census in 2014. Originally a part of Siheung County, Gyeonggi Province, it was transferred to Seoul with the rapid expansion of the National Capital Area (Sudogwon-Gijeon Region) due to its population growth and rapid industrialization in 1960s. The area which is dominated by Mount Gwanak was quickly changed the town into a mosaic of dense residential and industrial areas. Partitioned from Yeongdeungpo District and established as a district in 1973, it now neighbors the Seocho, Dongjak, Guro and Geumcheon Districts and exercises jurisdiction about 21 Administrative Precincts under 3 Legal Precincts.
Large slum quarters were formed by migrant populations from all over Korea who sought jobs in industrialized Seoul. A series of redevelopment projects from 1970s, and the relocation of Seoul National University to the district where the Original Campus in YeonGeon-dong, Seoul Jongno-gu was occupied by the Faculty of Medicine of SNU, led to a reduction of slum quarters and indigent textile industries and transformed the town into a residential uptown neighborhood of Seoul. The area is also heavily populated by SNU students from surrounding provinces.
