Eastern Administrative Okrug in the context of "Russian Census (2002)"

Zelenograd (Russian: Зеленоград, IPA: [zʲɪlʲɪnɐˈgrat], lit. 'green city') is a city and administrative okrug of Moscow, Russia. The city of Zelenograd and the territory under its jurisdiction form the Zelenogradsky Administrative Okrug (ZelAO), an exclave located within Moscow Oblast, 37 kilometers (23 mi) north-west of central Moscow, along the M10 highway. Zelenograd is the smallest administrative okrug of Moscow by area, the second-lowest by population, and the largest Moscow exclave by area and by population within Moscow Oblast. Zelenograd, if it were a separate settlement, would be the fifth-largest city in Moscow Oblast and one of the 100 largest cities of Russia. Before the expansion of the territory of Moscow in 2012, Zelenograd occupied second place among the administrative okrugs of Moscow, second only to the Eastern Administrative Okrug, in terms of the share of greenery in its total area (approximately 30%).

Zelenograd was founded in 1958 as a new town in the Soviet Union, and developed as a center of electronics, microelectronics and the computer industry known as the "Soviet/Russian Silicon Valley". It remains an important center of electronics in Russia. The city color is green and its emblematic animal is the squirrel.

The federal city of Moscow, Russia is divided into administrative districts called administrative okrugs, which are a subdivision of state administration. They are further divided into municipal formations called districts (raions) and settlements (poseleniy), which are local self-government entities.
