It covers a land area of 736.98 km2, and had a population of 126,100 at the 2010 census and 139,262 at the 2020 census; the official estimate as at mid 2022 was 140,165 (comprising 71,416 males and 68,749 females).

History 
Prior to rapid decentralization after the fall of Suharto, all of the archipelago to the north of the Minahasa Peninsula was administered as a single regency named Sangihe Islands and Talaud Regency. On 10 April 2002, it was split into two regencies, one for the Sangihe Islands and the other for the Talaud Islands, based on Law Number 8 of 2002. On 2 January 2007, several islands from the Sangihe Islands Regency were split off to create another new regency – the Sitaro Islands Regency – giving the Sangihe Islands its current status based on Law Number 15 of 2007.

It is believed that inhabitants of the Sangihe Islands migrated from the Philippines archipelago, especially from Mindanao. The culture of the native people in the islands has been influenced by Hinduism, Buddhism, and later, when the region was under Spanish hegemony, Christianity such as Kingdom of Manganitu under Bataha Santiago. Several native kingdoms existed such as Kendar Kingdom and Tabukan Kingdom, which later in the 18th and 19th centuries were described as partly influenced by Islam.

Geography 
Total area of the regency including water area is 11,863.58 square kilometres, from which only 736.98 square kilometres are land or 6.2% of total area of the regency. It is divided into 15 districts (kecamatan), the biggest being North Tabukan district, consisting of 15.82% of the regency's total land area and the smallest being Nusa Tabukan district with only 2% of total land area in the regency.

Topography of the islands mostly consists of hills and steep topography for bigger islands such as Sangihe and Siau. Around 55.4% of land area in the regency has slope above 40%. Soil composition consist of alluvium, which mostly used for residential areas. Elevation varies from 0 to 1,800 metres above sea level depending on the location. Main economic center of the regency, Tahuna, has average elevation of 250 metres above sea level. The regency has three active volcanoes, and experiences frequent earthquakes. Two of the three volcanoes are underwater. The region is quite resilient to erosion because of dense vegetation usually found on its coastal region, while most human settlements are found on higher altitudes in the middle of islands. However, because of its steep topography, the region is prone to landslides especially during bad weather.

As with most regions in Indonesia the Regency has a tropical climate and is affected by monsoons, with the rainy season experienced between September and November. Annual rainfall varies, depending on the island, from 2,500 to above 3,000 millimetres per year. There is little variation to temperature yearly, on average between 26 and 28 Celsius in the entire year. The region experiences high moisture levels ranging between 81 and 87% with average yearly of 83.6%.
