# Bolaang Mongondow Regency

Bolaang Mongondow Regency is a regency of North Sulawesi Province, Indonesia, situated on the island of Sulawesi. The principal town lies at Kotamobagu, which since 2007 has been administratively separated from the regency, the administrative centre of which is now at the town of Lolak. The regency covers a land area of 2,933.6 km$^2$, and had a population of 213,484 at the 2010 Census and 248,751 at the 2020 Census; the official estimate as at mid 2023 was 254,945 (comprising 132,717 males and 122,228 females).

## Administrative Districts

Until 2007 the Regency included a much larger share of the territory off North Sulawesi Province, but on 2 January 2007 the town of Kotamobagu was split away to become an independent city, while northern districts of the regency were similarly split off on the same day to create a new North Bolaang Mongondow Regency. On 24 June 2008 two further regencies were created from other parts of the regency - South Bolaang Mongondow and East Bolaang Mongondow. At the time of the 2010 Census the residual Regency was divided into twelve districts (kecamatan), but three additional districts have subsequently been created by splitting of existing districts.
Under consideration by the Indonesian government since 2013 has been a proposal to re-unite the pre-2007 territories into a new province covering the same area as the original Bolaang Mongondow Regency, and separated from North Sulawesi, but all such proposals have been held in abeyance since 2013.
The fifteen districts are tabulated below with their areas and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2023. The table also includes the location of the district administrative centres, the number of administrative villages in each district, totaling 200 rural desa and 2 urban kelurahan - the latter being Inobonto (in Bolaang District) and Imandi (in Dumoga Timur District) - together with its postal codes.
