The Moscow metropolitan area includes the city of Moscow, population 12,197,596,^[4] a ring of cities annexed to it and administered within (Balashikha, Korolyov, Krasnogorsk, Khimki, Mytishchi and Zelenograd), as well as large nearby towns with population of over 100,000 citizens (Reutov, Zheleznodorozhny, Podolsk and Lubertsy, to name a few) that fall under regional administration.^[5] Administratively, all those towns are a part of the Moscow Oblast. The metropolitan area has thus no coordinated administration structures, and no official population statistics.

The population of the Moscow region is the sum of populations of the city (13,010,112) and surrounding oblast (8,524,665), coming to 21,534,777 – about 14% of the entire Russian population.
