The Surabaya metropolitan area or Greater Surabaya, known locally as Gerbangkertosusila (Javanese: ꦒꦼꦂꦧꦁ​ꦏꦼꦂꦠꦱꦸꦱꦶꦭ, romanized: Gěrbangkěrtåsusila, from Gresik-Bangkalan-Mojokerto-Surabaya-Sidoarjo-Lamongan), is a metropolitan area in East Java, Indonesia. It is the country's second-largest metropolitan area, after Jakarta metropolitan area. Gerbangkertosusila had also been used in presidential decree to refer to larger region which include Jombang, Bojonegoro, and Tuban.

Definition

Grebangkertosusila is an official acronym of "Gresik Bangkalan Mojokerto Surabaya Sidoarjo Lamongan", a main metropolitan or planning area in East Java consisting of the seven cities and regencies with those names (Mojokerto is both a city and a separate regency). It has an area of 6,310.06 km, and at the 2020 Census had a population of 9,924,509, rising to 9,975,878 according to the official estimates as at mid 2022.

The national government regards the Surabaya Metropolitan Area as including only Surabaya, Sidoarjo Regency, and Gresik Regency, known as "Zona Surabaya Raya". Gresik Regency includes Bawean Island, covering some 196 km and lying north of Java; however Bawean Island is excluded from the Metropolitan Area.

Demographics

Surabaya traditionally constituted Indonesia's second-largest metropolitan area, after Jakarta, but fast growing Bandung Metropolitan Area (in West Java) is since 2005 more populous. However, the extended metropolitan area of Surabaya is second in Indonesia only to Jabodetabek. The areas and populations at the 2010 Census, the 2020 Census and according to the official estimates for mid 2022, are shown below for the component parts of the metropolitan area.

Note: (a) The island of Bawean, while part of Gresik Regency, is not technically part of the Metropolitan area; nevertheless for convenience the figures given here include Bawean.
