Batam

The city of Batam includes Batam Island at 410 square kilometres (160 mi2), as well as other major islands such as Rempang at 165 square kilometres (64 mi2) and Galang at 80 square kilometres (31 mi2). Together, the three-interconnected islands of the Riau Archipelago are known as Barelang. The remaining hundreds of tiny islands are largely conservation areas, small fishing outposts, or uninhabited mangroves. Collectively, the land area of all these islands make up around 1,020.28 square kilometres (393.93 mi2). Batam Island is the core urban and industrial zone, while both Rempang Island and Galang Island maintain their rural character and low-density population; they are connected to Batam Island by short bridges. Bulang Island and the islands to its north lie to the west of Batam Island; while they are part of the Belakang Padang District, they are also administratively within the city.

Batam City is an industrial boomtown, an emerging transport hub and part of a free trade zone in the Indonesia–Malaysia–Singapore Growth Triangle, located 20 km (12 mi) off Singapore's south coast.
