Greater Jakarta (Indonesian: Jakarta Raya) is the urban agglomeration surrounding Jakarta, Indonesia, the capital and largest city in the country. There are multiple definitions, all of which rank Greater Jakarta among the largest urban agglomerations on the planet.
Jakarta and Greater Jakarta in general, are home to people from all over Indonesia and Southeast Asia, as well as a sizeable expatriate population. The native and majority Sundanese resides in Greater Jakarta, along with significant numbers of Javanese, Betawi as well as Bataks from the rest of the island.
Jabodetabek Definition 
The definition of Jabodetabek is the basis for all metropolitan area definitions, however, it became a former designation in 2011.
Various Names and Definitions 
As Greater Jakarta continued its rapid growth and sprawl over the decades, definitions are modified and municipalities (kota) coalesced out of regencies. Names grow longer as syllables of cities are tacked on the ends. Initially, the metropolitan area was defined as:
- Jabotabek, the combination of "Ja"karta + "Bo"gor + "Ta"ngerang + "Be"kasi cities (Kota) and Regencies (Kabupaten), this name was rendered obsolete when "De"pok was added.
- Jabodetabek, Depok was carved out of Bogor Regency in 1999, leading to the new name (but covering the same area as Jabotabek) Similarly, South Tangerang was carved out of Tangerang Regency, without a name change or area change. Former official government designation, which in turn became obsolete in 2011 (however, this name and definition are still in popular use).
- Jabodetabekjur, The "new" official government definition since 2011, Jabodetabek definition has been further extended to include the sprawl into the northern section of Cianjur Regency, covering 4 kecamatan (see map), namely Sukaresmi, Pacet, Cipanas, and Cugenang, increasing the area of the metropolitan area, to Jabodetabekjur. There is a government agency, BKSP Jabodetabekjur, assigned to be responsible for the development of Greater Jakarta, along with a map of its coverage. These areas of Cianjur are not particularly urban, the addition of them is purely related to definition, not necessarily built-up area.
- Jabodetabekpunjur, variation of Jabodetabekjur including the town of Puncak which already lies in the territory covered by Jabodetabekjur.
Furthermore, as the region is densely populated and large cities lie just outside even this definition, the following table has been provided:

Surrounding Region 
Surrounding the defined regions of Greater Jakarta, continues some densely populated communities. Greater Bandung, home to 8 million people, is adjacent to Purwakarta and Cianjur, far flung suburbs of Jakarta. The suburban zone around Sukabumi ringing Mount Gede is home to 1.8 million residents, itself amalgamating with the section of Cianjur, the part which has been officially added to the definition of Greater Jakarta. Rankasbitung and Labuan, Pandeglang border the Serang Regency and Tangerang Regency to the south, and are in the process of amalgamation with the greater metropolitan region.
