The Sigi Regency was divided at 2010 and at 2020 into fifteen
districts (
kecamatan), but on 14 September 2020 a sixteenth district (
Sigi Kota) was formed from parts of Sigi Biromaru (7
desa), Dolo (2
desa) and Palolo (1
desa) Districts. The districts are tabulated below with their areas and their populations at the 2010 Census The table also includes the locations of the district administrative centres, and the numbers of
villages (all rated as rural
desa) in each district. For ease of reference, they are grouped below into two sectors (which have no administrative function); the southern group forms the geographically larger but less well populated part of the regency in the extensive valley of the
Palu River, with an average population density of 27 per km2, while the northern group forms the geographically smaller but more populated and faster-growing area to the immediate south of the city of
Palu, with an average population density of over 204 per km2. The southern part includes the large
Lore Lindu National Park. Note (a) the population of the new Sigi Kota District in 2010 and 2020 is included in the figures for Sigi Biromaru (8
desa), Dolo (2
desa) and Palolo (1
desa) Districts, from parts of which it was created on 14 September 2020. ==References==
