Long-term Russian demography forecast

Three methods considered for forecasting the population dynamics of Russia in the range 2005–2105. First method is based on the general demographic indicators. Illustrated that compensation of the depopulation is possible only by external migration. Second method is based on cohort analysis (age-groups population differentiation considered). It is shown that current migration inflow is badly insufficient. Third method replace whole population with two groups with different demography indicators. Conclusion is break of depopulation due to rapid growth of groups with high birth-rate.
