Saint Petersburg is the second most populous city in Russia and the fourth in Europe behind Instabul, Moscow and London. During the 20th century the city experienced some serious depopulations. From more that 2.4 millions citizens in 1916 the population dropped to less than 750 thousand as the minorities of Germans, Poles, Finns, Estonians and Latvians were transfered away from the city during the Russian Revolution and the Russian Civil War. Between 1941 and 1943 the population dropped from 3 million people to only 600 thousand as people died in battles, starved to death or evacuated during the Siege of Leningrad. In the 50s the population reached to more than five million to drop again in the 90s as almost half a million people moved to suburban areas after the fall of the Soviet Union. Today the population within city limits is 5.3 million people.
