ИСТИНА

For many years, the Russian Federation has been attracting large numbers of long-term and temporary migrants, which reinforces the importance of correct measurement of these phenomena. During the post-Soviet period, the country has established and developed a system of data sources, (mainly administrative), reflecting the extent and impact of migration. Without these data it is difficult to analyze the full range of consequences of migration for Russia. The paper provides information on existing and potential sources of administrative data on international migration, in relation not only to the migrants flows and stocks, but also health of migrants, crime, economic activity and impact on demographic processes. The paper also deals with the situation in the field of the Federal statistical observation of long-term migration flows, dependence of statistics on institutional and organizational factors, and the prospects of solving existing problems.
