Following the Regional Autonomy Act () of 1999, many regencies were split to create additional regencies and cities, the number of such divisions was thus increased to 514 by 2014. However, these territorial splits can sometimes lead into corruption cases. As at early 2024, all further proposals for territorial splits are still under a
moratorium. The latest new regencies split from existing regencies were
South Buton Regency,
Central Buton Regency and
West Muna Regency in July 2014, while the latest cities were
South Tangerang and
Gunungsitoli in October 2008. There are no cities which have been split into other subdivisions, although the administrative regency of
Thousand Islands was split from
North Jakarta administrative city in 2001. Despite the name of South Tangerang being similar to that of
Tangerang city, South Tangerang was actually split from
Tangerang Regency. In two special cases, all subdivisions of
North Maluku and
Riau Islands were made from parts of the defunct North Maluku Regency and Riau Islands Regency, respectively. All subdivisions of
North Kalimantan are also made from lands of
Bulungan Regency, but its area was split to several regencies before the province was established.
Central Java (since 1965) and the
Special Region of Yogyakarta (apart from the separation of the
Thousand Islands Administrative Regency from North Jakarta City) are the only province-level areas which have not had any subdivision splits. Listed below are the subdivision splits from 1999 to the most recent ones in 2014; for pre-1999 splits see also
main article in Indonesian Wikipedia.
