Greater Malang (Indonesian: Malang Raya) is a region in East Java, Indonesia, encompassing the municipality of Malang and its hinterland. About 3 million people in East Java reside in Greater Malang. The principal city, Malang is well known as the home of notable universities in Indonesia,[4] and the nearby Batu (now also an independent city), is well known as a tourism centre in East Java.[5]
In the Dutch colonial era, Greater Malang was a residency, an old form of second-tier subdivision, called Karesidenan Malang (Malang Residency), consisting of four cities (Malang, Batu, Pasuruan, Probolinggo) and four regencies (Malang Regency, Pasuruan Regency, Probolinggo Regency, Lumajang Regency).[6] [7] But now, the definition of Greater Malang just consists of the Malang highlands area, namely Malang city, Batu city, and Malang Regency, together with one district (kecamatan Purwodadi) of Pasuruan Regency.[8] Even this is excessive, as parts of Malang Regency - the 9 districts in the south (bordering the south coast of East Java) and the 3 districts lying west of Batu city - are not part of the Malang Valley urbanisation. The component parts are tabled below, with their areas, their populations at the 2010 and 2020 Censuses, and the official estimates as at mid 2023.[9]
