  • Some characteristics of migration processes in Russia and the Republic of Karelia

    The characteristics of the migration processes in Russia and the Republic of Karelia. Shown that research in the field of promotion of the Russian language and Russian as a foreign language as a native language in Russia and abroad have seen in close conjunction with the analysis of migration processes associated with the need for teaching Russian adapting foreign citizens in the country. The analysis showed that the transition to a "quiet" conditions of a market economy after the 2000 cross-country movement of labor with Russia intensified: the capacity of the Russian labor market and the increased mobility of Russians led the growth of migration flows, Russia as a whole remains a "host" side - the number of labor migrants in Russia considerably exceeds the number of Russians traveling to work abroad. Such a situation is typical for the Republic of Karelia. A comparison of labor migration on vocational qualification groups
