Murmansk is the largest city in the polar circle. 310 thousand people lived there in 1971. In 20 years the population has grown to almost half a million. This was due to the growth of the fishing and naval industries and huge progress in all areas of city life. People moved to the North from all over Soviet Union.
Nowadays demographic decline is observed in Murmansk. Since 1998 the population has decreased by almost 100 thousand people. The most of people leaving the town is the youth. It depends on the fact that central and secondary regions are experiencing different growth rates of living standards.
This problem is relevant for the huge amount of cities throughout Russia. If the trend continues, many cities may disappear from the map. Murmansk is one of the many «melting» cities in Russia.
