The Seoul Capital Area has a population of 25.6 million (as of 2012) and is ranked as the second largest metropolitan area in the world. Its area is about 11,704 km2. It forms the cultural, commercial, financial, industrial, and residential center of South Korea.

Geography and climate
The Capital Area occupies a plain in the Han River valley. It contains some of the most fertile land on the Korean peninsula, although relatively little of it is now used for agriculture. The Gimpo Plain, one of the country's larger expanses of level arable land, covers much of the area of the cities of Gimpo and Bucheon.
