Seoul is a Megacity
The capital and largest city of South Korea is Seoul. Its population is around to 10 million, or almost 1/5 of all Koreans. Because it has a population of more than ten million, it is regarded as a megacity. In Seoul's National Capital Area, about half of the city's inhabitants live (which also includes Incheon and Gyeonggi). With more than 25.6 million inhabitants, the Seoul Capital Area is the second-largest metropolitan area in the world. It has the sixth-highest population density worldwide.
In terms of overall quality of life, Seoul ranked seventh in the world in 2016, according to data from the Sustainable Cities Index by design and consulting company Arcadis. The city's economy represents 67 percent of the country's GDP, with a gross domestic product (GDP) of $903 billion, according to data from Oxford Economics, an advising business, for 2015. The Global Power City Index 2017, created by the Institute for Urban Strategies of the Mori Memorial Foundation, ranks cities based on six factors, including economy, research, culture, liveability, and accessibility. Seoul is ranked sixth, surpassing cities like Hong Kong.
The corporate headquarters of Samsung and LG are located in Seoul. Then there are programs that link business with urban development. The Digital Media City, a facility with more than 500,000 square meters of space devoted to digital technology, is one such. Since its construction in 2002, it has drawn cutting-edge businesses from the high-tech industry. The Gangnam district became home to Google's first Asian campus for start-ups in 2015, demonstrating the city's dynamism. Therefore, it should not be surprising that the city ranks well in the United Nations' ICT Development Index and is considered one of the world's broadband capitals.
