At the time of the 2010 Census, Samarinda City was divided into six
districts (Indonesian:
kecamatan), but four additional districts were subsequently created by splitting of existing ones. The ten 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 2025. The table also includes the number of urban villages in each district (all classed as urban
kelurahan) and their post codes. Notes: (a) the 2010 populations of Samarinda Kota and Sambutan Districts are included in the 2010 figure for Samarinda Ilir District, from which they were later split off. (b) the 2010 population of Loa Janan Ilir District is included in the figure for Samarinda Seberang District, from which it was later split off. (c) the 2010 population of Sungai Pinang District is included in the figure for Samarinda Utara District, from which it was later split off.
Territorial evolution During its early days after its formation in 1960, Samarinda initially only consisted of 2 districts, namely Samarinda Kota (not to be confused with the
current district that was formed in 2010) and
Samarinda Seberang (both comprised a total area of 167 km2, and each located north and south of the Mahakam). Then, Samarinda Kota was bifurcated into Samarinda Ilir and Samarinda Ulu (date unknown).
Sanga-Sanga,
Muara Jawa and
Samboja were transferred from Kutai Regency to Samarinda, therefore, its total area increased to around 2,727 km2. This move was related to the enormous size of Kutai Regency at the time, causing ineffectivity in public service, as well as the closer proximity of four districts with Samarinda rather than with
Tenggarong, the capital city of Kutai. The districts were also home to several major companies active in oil and gas sector, and it was hoped to bring that revenue into Samarinda's government. However, the previous annexations of 1969 instead brought reverse effects into both Samarinda and
Balikpapan, as only below 5% of their total areas were usable, while being inhabited by less than 300,000 people at the time. The cities made multiple negotiations in 1985 with the governments of Kutai and
Pasir regencies, respectively, in order to alter each other's boundaries. It culminated on significant reduction of the cities' territories on 13 October 1987, where Sanga-Sanga, Muara Jawa, and Samboja were separated from Samarinda and soon attached to Kutai (Palaran remains part of the city). In exchange, Samarinda received 6 villages from neighbouring few districts of Kutai Regency, namely Bantuas (from Sanga-Sanga, attached to Palaran); Loa Buah and Loa Bakung (from
Loa Janan, attached to Samarinda Ulu); Loa Janan Ilir (from Loa Janan, attached to Samarinda Seberang); Sungai Kapih, Sambutan, and Pulau Atas (from Anggana, attached to Samarinda Ilir). On 11 June 1996, under Government Regulation Number 38 of 1996, the districts of
Sungai Kunjang and
North Samarinda were created from parts of Samarinda Ulu and Samarinda Ilir, respectively. Four years forward on 23 February 2001, the remaining rural vilages () of Sambutan, Sindang Sari, Makroman, Pulau Atas, Sungai Kapih, Loa Buah, and Simpang Pasir changed their statuses into urban counterparts (). On 22 February 2006, new 11 urban villages were created from existing ones: Sengkotek and Tani Aman (from Loa Janan Ilir, then renamed as Simpang Tiga), Rapak Dalam (from Baqa), Tanah Merah (from Lempake), Bandara (from Pelita), Gunung Lingai (from Temindung Permai), North Sempaja (from Sempaja, then renamed as South Sempaja), Mugirejo (from Sungai Pinang Dalam), Bukit Pinang (from Air Putih), Karang Asam Ilir (from Karang Asam, then renamed as Karang Asam Ulu), and Karang Anyar (from Teluk Lerong Ulu). On 14 December 2010, four new districts were created in Samarinda, namely
Samarinda Kota (from Samarinda Ulu and Samarinda Ilir),
Sambutan (from Samarinda Ilir),
Sungai Pinang (from North Samarinda), and
Loa Janan Ilir (from Samarinda Seberang). As a result, the administrative capitals of Samarinda Ilir and North Samarinda were relocated from Sambutan and Sungai Pinang Dalam villages to Sidomulyo and Lempake, respectively. The latest creation of new villages occurred on 12 August 2014, resulting on Mangkupalas and Tenun (from Mesjid), Gunung Panjang (from Sungai Keledang), West Sempaja and East Sempaja (from South Sempaja), and
Budaya Pampang (from Sungai Siring). ==Climate==
