[Genetic-demographic processes in the Muscovite population in the mid-1990s. Migration and emigration as a factor for changing the genetic diversity of the population].

On the basis of official migration statistics and marriage records, the genetic parameters of migration in the Moscow population over the past 120 years were determined. Although the number of officially registered migrants decreased, the coefficient of marriage migration in the mid-1990s was higher than in the mid-1980s (m = 0.4). The in-migrants considerably differed from Moscow-born residents with respect to their age at marriage, ethnicity, level of education, and speciality. The emigration of the Moscow residents to foreign countries was selective with respect to the educational level and adversely affected the labor, intellectual, and cultural resources of Moscow (the "braindrain"). In the long run, the observed ethnic differences between in-migrants and emigrants may considerably influence the ethnic composition and, hence, genetic diversity of the Moscow population.
