The government of Indonesia defines a metropolitan area as an urban agglomeration where its spatial planning is prioritised due to its highly important influence on the country.
[1] The metropolitan areas in Indonesia are managed based on Presidential Regulation (Peraturan Presiden).
The national government has established 10 metropolitan areas across the country, anchored by the cities of Jakarta, Surabaya, Bandung, Semarang, Medan, Makassar, Palembang, Denpasar, Banjarmasin, and Manado.
Despite having no official metropolitan areas recognised on national level, there are several other cities whose urbanised area exceeds their city limits such as Yogyakarta, Malang, and Cirebon.
Demographia defines an urban area (urbanised area agglomeration or urban centre) as a continuously built up land mass of urban development that is within a labor market (metropolitan area), without regard for administrative boundaries (city).
