What to Know About Sidoarjo

Key Facts

Sidoarjo is a regency located in the eastern part of East Java province, Indonesia. Positioned strategically in the northeastern region of Java Island, Sidoarjo serves as an important economic and industrial hub with its proximity to Surabaya, Indonesia's second-largest city. The regency covers an area of approximately 634.89 square kilometers and has a population of around 2.1 million people according to recent estimates, making it one of the most densely populated regions in East Java. Sidoarjo is administratively divided into 18 districts (kecamatan) and 322 villages (kelurahan/desa), reflecting its complex urban-rural character. The region is particularly notable for the 2006 Lusi mud flow disaster, one of the largest mud volcanoes in the world, which has significantly impacted the local landscape and economy. Despite this challenge, Sidoarjo maintains a diverse economy with strong agricultural, industrial, and commercial sectors, benefiting from its location along major transportation corridors connecting Surabaya with other parts of eastern Java.
