Contribution of Senior Age Groups to Changes in Life Expectancy Indicators for Russia’s Megalopolises (Moscow and St. Petersburg)

Abstract

This study analyzes the dynamics of life expectancy at birth (LE₀) and at older ages and the contribution of older ages (60+) to changes in life expectancy in Russian megacities Moscow and St. Petersburg. We studied the contributions of aggregated age groups to differences between LE₀ values for Moscow and St. Petersburg. Our study has shown that the increase in life expectancy at senior ages makes a significant contribution to the increase of the LE₀ index.
