Moscow oblast
Moscow oblast (MO) - not the most common example of subject of the Russian Federation: while the other regions tend to have a pronounced regional center, which is often the same name of the territory, in the Moscow region such a center is the city of Moscow, which has the status of a separate Federation subject.

In total the region has more than 70 cities, of which about 20 have a population exceeding 100 thousand people. However, even these cities it's hard to call large, especially in comparison with Moscow: the most numerous are the Khimki and Balashikha, the population of each of which exceeds 200 thousand people.
