Moscow, Russia

Capital City

You'll need steel nerves and a fat wallet to thrive in Moscow. With a population of over 13 million and a per capita GDP double the national average, this is one of the world's most expensive and densely populated cities. While the metro system is a marvel of Soviet engineering, bureaucracy is a persistent headache, and the brutal winters can test even the hardiest residents. Only those undaunted by the challenges will find Moscow's world-class culture, art, and economic opportunities worth the cost of living.
