Khanty-Mansi Autonomous Okrug–Yugra in the context of "Ugrians"

Nizhnevartovsk (Russian: Нижневартовск, IPA: [nʲɪʐnʲɪˈvartəfsk]) is a city in Khanty-Mansi Autonomous Okrug–Yugra, Russia. Since the 1960s, the Western Siberian oil boom has led to Nizhnevartovsk's rapid growth from a small settlement to a city due to its location beside the Samotlor oil field along the right bank of the Ob River, 30 kilometers (19 mi) from the border with Tomsk Oblast, and the presence of the petroleum industry has made it one of the wealthiest cities in Russia.

Nizhnevartovsk is one of the few cities in Russia that exceeds the population of the administrative center of its federal subject. Population: 283,256 (2021 census); 251,694 (2010 census); 239,044 (2002 census); 241,457 (1989 Soviet census).

Khanty-Mansiysk (Russian: Ха́нты-Манси́йск, romanized: Khánty-Mansíysk, lit. Khanty-Mansi Town; Khanty: Ёмвоҷ, Jomvoćś; Mansi: Абга, Abga) is a city in west-central Russia. Technically, it is situated on the eastern bank of the Irtysh River, 15 kilometers (9.3 mi) from its confluence with the Ob, in the oil-rich region of Western Siberia. Though it is an independent city, Khanty-Mansiysk also functions as the administrative centre of Khanty-Mansiysky District, and the administrative center of Khanty-Mansi Autonomous Okrug–Yugra.

With 101,466 estimated inhabitants, Khanty-Mansiysk is among Russia's few regional capitals that are not the largest cities in their surrounding area, as it is surpassed in population by Surgut, Nizhnevartovsk and Nefteyugansk.
