# South Nias Regency

Nias Selatan (South Nias) Regency is a regency in North Sumatra province, Indonesia, created on 25 February 2003 by the division of the existing Nias Regency. The regency covers a land area of 2,487.99 square kilometres and according to the 2010 census had a population of 289,708; the 2020 Census showed a population of 360,531, while the official estimate for mid 2023 was 368,834.

Apart from the southern portion of Nias Island, the regency also includes the smaller Batu Islands (Pulau Pulau Batu) to the south, lying between Nias and Siberut; these islands occupy nearly half of the land area of the Regency, but have just 9% of its population.

## Administrative districts

The regency was divided into eighteen districts (kecamatan) at the time of the 2010 Census, However, since 2010 seventeen additional districts have been created from parts of existing districts, notably in the Batu Islands where there are now seven districts compared with the three in 2010, but also on Nias Island itself where there are now twenty-eight districts within the Regency compared with fifteen in 2010. These are all tabulated below with their areas (in km$^2$) and their populations at the 2010 Census, and the 2020 Census, together with the official estimates as at mid 2023. They are grouped geographically (these groupings have no administrative significance). The table also includes the locations of the district administrative centres, the number of administrative villages in each district (a total of 459 classed as rural desa and 2 classed as urban kelurahan), and its postal code.
