Jakarta, officially the Special Capital Region of Jakarta, is the capital and largest city of Indonesia. Lying on the northwest coast of Java, the world's most populous island, Jakarta is the largest city in Southeast Asia, and serves as the diplomatic capital of ASEAN. The city is the centre of the economy, culture, and politics of Indonesia. It has a province level status which has a population of 10,562,088 as of 2020. Although Jakarta extends over only 664.01 square kilometres (256.38 sq mi), and thus has the smallest area of any Indonesian province, its metropolitan area covers 9,957.08 square kilometres (3,844.45 sq mi), which includes the satellite cities Bogor, Depok, Tangerang, South Tangerang, and Bekasi, and has an estimated population of 35 million as of 2021, making it the largest urban area in Indonesia and the second-largest in the world. Jakarta ranks first among the Indonesian states in human development index. Jakarta's business opportunities, and its ability to offer a potentially higher standard of living than is available in other parts of the country, have attracted migrants from across the Indonesian archipelago, making it a melting pot of numerous cultures.
