(Indonesian: kecamatan), which comprise 604 villages (Indonesian: gampong). The areas of the districts and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2021, are listed below. These are grouped below into three sections for convenience, which have no administrative significance. The table also includes the locations of the district administrative centres, the number of administrative villages (gampong) in each district, and its post code. Notes: (a) comprises a group of islands off the north-western tip of Sumatra, of which the largest are Pulau Breuh, Pulau Nasi and Pulau Teunom. (b) includes some smaller islands off the north-western tip of Sumatra but closer to the mainland than Pulo Aceh District - Pulau Bunta and Pulau Batee. (c) comprises southern suburbs of Banda Aceh city, with 105,835 inhabitants in mid 2021. Rusa Island Rusa Island in Lhoong district was shaped like Rusa (deer) before the tsunami struck the island on 26 December 2004, but now that much of it has been washed away, the form of the island has changed and become smaller like a lamb embryo. The island is very important for marking Indonesia's boundaries due to its location as the most westerly island in Indonesia with Titik Dasar TD175 and Titik Referensi TR175 (Base Point TD175 and Reference Point TR175). Bunta Island Since the 2004 tsunami struck Bunta island, 45 minutes by traditional motorised boat from Ujong Pancu Village, Peukan Bada, there are no longer any inhabitants living there. Nowadays some people use the island as a coconut plantation, but they live in Banda Aceh. As the tsunami washed out all of the living creatures there, nowadays there are no squirrels, monkeys or snakes on the island. The island has been popularized by the documentary film Hikayat di Ujung Pesisir and is ideal for camping, but with no facilities at all, and modest snorkeling can be done there.
