Accounting for ethnicity is carried out within the framework of current accounting and the All-Russian Population Census. It is noted that access to more precise information is necessary for the formation of migration and national policies. It is proposed to use the experience of foreign countries in data recording on the parents’ place of birth. This expands the information about the ethnic and cultural roots of the respondents. The results of the survey confirm the statistical data on the growth of ethnocultural diversity in the regions of Russia. The changes take place due to the increase in the number of immigrants, seasonal migration, as well as the implementation of the State Program for the resettlement of compatriots. It is shown that in most regions there is no state body responsible for the adaptation and integration of migrants. On the part of migrants, it is important to know the Russian language, Russian legislation and the profession that is in demand in the region. It was proposed to form an operating mechanism for the adaptation of migrants and to consider a new approach to the collection of statistical data.
