Tools for predictive calculations of migration indicators that characterize the retention of migrants in the territories of arrival in Russia

The paper presents the process of developing multiple regression equations that can be used in predicting indicators of migrants ' retention in the territories of arrival in modern Russia. These indicators include the effectiveness and efficiency of migration, migration growth and survival rates of migrants. All migration flows, movements within Russia, Russian interregional migration, international flows and movements within the regions of the Russian Federation are studied. Fourteen basic and two auxiliary multiple regression equations were formed. Based on the developed multiple regression equations, it is possible to manage the processes in the field of migration of the Russian population in the implementation of state economic policy The source of the information was Rosstat's statistical indicators for all administrative-territorial units of the Russian Federation for 2018. The total array of studied indicators was 54636.
