Nias is the largest of the islands off Sumatra that are part of
North Sumatra province. This archipelago consists of 131 islands, of which Nias Island is the biggest. The population in this area was 756,762 inhabitants at the 2010 Census, including
Ono Niha (the indigenous inhabitants of the island),
Malay,
Batak, and
Chinese; by the 2020 Census the population had risen to 880,550, and the official estimate as at mid 2024 was 946,746. Until 2003
Nias was a single administrative
regency (
kabupaten) covering the entire island, part of the province of
North Sumatra. On 25 February 2003, it was split into two regencies, Nias Regency (covering the northern half of the island) and South Nias Regency (
Nias Selatan), the latter including the
Batu Islands further south. Subsequently, on 20 October 2008, the island was divided further, with the creation of two further regencies from parts of the former Nias Regency – Nias Barat (West Nias) and Nias Utara (North Nias) – and the designation of Gunungsitoli as an autonomous city independent of the four regencies.
Gunungsitoli remains the center of the business affairs of the entire island.
Teluk Dalam is the capital of Nias Selatan Regency, Lötu of Nias Utara Regency, Lahömi of Nias Barat Regency, and Gidö of Nias Regency. All parties in the North Sumatra Legislative Council have agreed to the formation of a
Nias Province (comprising Nias, Nias Selatan, Nias Utara and Nias Barat regencies, and Gunungsitoli municipality), to be separated from North Sumatra Province. It was approved at a regional plenary session on 2 May 2011 but still awaits approval from the Central government, which has not yet enacted the grand design for additional provinces and has imposed a moratorium on such new creations. The new province will thus cover an area identical to the original Nias Regency before the latter's division in 2003. Apart from
Nias Island itself, the province will include the smaller
Batu Islands (Pulau-Pulau Batu) to the south, lying between Nias and
Siberut; the Batu Islands form seven administrative
districts within South Nias Regency. : # South Nias Regency includes the
Batu Islands. ==Culture==
