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 regency).[2][3] It has an area of 5,925.843 km2, and at the 2020 Census had a population of 9,924,509.[4]
The national government regards the Surabaya Metropolitan Area as including only Surabaya, Sidoarjo Regency, and Gresik Regency, known as "Zona Surabaya Raya".[5] Gresik Regency includes Bawean Island, covering some 196 km2 and lying north of Java; however Bawean Island is excluded from the Metropolitan Area.
