Russia has 21 republics:
one autonomous region: Jewish;
ten autonomous national areas:
49 Russian regions (the cities of Moscow and St. Petersburg also have region status);
and six Russian territories.
Oblasts and krays are roughly equivalent to provinces.
In 2000 the administrative units of Russia were grouped into seven regional administrative districts. The districts (and their administrative centres) are Northwest (St. Petersburg), Central (Moscow), Volga (Nizhny Novgorod), North Caucasus (Rostov-na-Donu), Ural (Ekaterinburg), Siberia (Novosibirsk), and Far East (Khabarovsk).
After the dissolution of the Soviet Union in 1991, all of the former autonomous republics of the RSFSR were raised to full republic status, and four of the autonomous regions (Adygeya, Altay, Karachaevo-Cherkessia, and Khakassia) were made full republics as well.
In addition to Moscow, other major urban areas in Russia include St. Petersburg, Nizhny Novgorod, Rostov-na-Donu, Volgograd, Kazan, Samara, Ufa, Perm, Ekaterinburg, Omsk, Chelyabinsk, Novosibirsk, and Vladivostok.
