Population Dynamics in Multinational Russia in the 1920s

The article analyzes the results of the crisis decade (1914)(1915)(1916)(1917)(1918)(1919)(1920)(1921)(1922) in Russian history.During these years, the country experienced the First World War and the Civil War, revolutions, intervention, political terror, epidemics, and the famine of 1921-1922, as well as changes in its borders.These events had a significant impact on the population, gender distribution, and age groups.The author explores the positive trends in the demographic development of the country and its peoples that emerged after the end of the Civil War, the demobilization of the army, and the introduction of the New Economic Policy.In the 1920s, pandemics and epidemics were defeated, mortality rates decreased, and birth rates and life expectancy increased.The article explores the demographic development of Russia's "major" ethnic groups and their significance for the sustainable development of a multi-ethnic country.The balance of population reproduction depended on exogenous and endogenous factors.Exogenous factors, such as famine, epidemics, deportations, terrorism, changes in borders, and mass migrations, had a negative impact on the growth rate of ethnic groups.Endogenous processes, on the other hand, had a positive effect on population dynamics.Internal processes include the established type of population reproduction and the traditional way of life of the peoples.
