Jakarta, officially the Special Capital Region of Jakarta, is the capital and largest city of Indonesia and an autonomous region at the provincial level. Lying on the northwest coast of Java, the world's most populous island, Jakarta is the largest metropole in Southeast Asia and serves as the Headquarters of ASEAN. The Special Region has a status equivalent to that of a province and is bordered by the province of West Java to the south and east and Banten to the west. Its coastline faces the Java Sea to the north, and it shares a maritime border with Lampung to the west. Jakarta's metropolitan area has an estimated population of 41.9 million as of 2025, making it the largest urban area in Indonesia and the world; in addition of being ASEAN's second largest economy after Singapore.
Jakarta is the economic, cultural, and political centre of Indonesia. Although Jakarta extends over only 661.23 km (255.30 sq mi) and thus has the smallest area of any Indonesian province, its metropolitan area covers 7,076.31 km (2,732.18 sq mi), which includes the satellite cities of Bogor, Depok, Tangerang, South Tangerang, and Bekasi. Jakarta ranks first among the Indonesian provinces in the human development index. Jakarta's business and employment opportunities, along with its ability to offer a potentially higher standard of living compared to other parts of the country, have attracted migrants from across the Indonesian archipelago, making it a melting pot of numerous cultures.
