Population exchange is the transfer of two populations in opposite directions at about the same time. In theory at least, the exchange is non-forcible, but the reality of the effects of these exchanges has always been unequal, and at least one half of the so-called "exchange" has usually been forced by the stronger or richer participant.

Rural flight did not occur uniformly throughout the USSR. Western Russia and the Ukraine experienced the greatest declines in rural population, 30% and 17% respectively. Conversely, peripheral regions of the USSR, like Central Asia, experienced gains, contradicting the general pattern of rural-urban migration of this period. Increased ...
The pre-history of Eurasia is characterized by a pattern of migration, invasion, melding of population and displacement and this is attributed to its location. [1] Its plains, which are nestled between the Baltic and Black seas, offer a wealth of natural resources and room for expansion, especially with easy access to river routes.
European emigration is the successive emigration waves from the European continent to other continents. The origins of the various European diasporas [1] can be traced to the people who left the European nation states or stateless ethnic communities on the European continent.
