Oblasts of Russia
Oblasts are divided into raions (districts), cities of oblast significance (district-equivalent independent cities), and autonomous okrugs. These are legally federal subjects equal to an oblast but are different from others. Two oblasts have autonomous okrugs: Arkhangelsk Oblast (Nenets Autonomous Okrug) and Tyumen Oblast (Khanty-Mansi Autonomous Okrug and Yamalo-Nenets Autonomous Okrug).
