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.
