Moscow-based investment bank Renaissance Capital also expects this segment of the demography to spur politically risky pension reforms.
Russia's pension system is coming under increasing strain thanks to growing life expectancy -- particularly among women -- and a shrinking labour force due to the collapse in birth rates in the 1990s.
Since the introduction of the current system, the average life span of the Russian man has risen to 63.4 years, up from 58.7. Over the same period of time, the life expectancy for the country's women has risen to 75.4 years, up from 71.9.
Russian women are thus likely to claim a pension for 20 years after retirement at 55. Compare this to the three to four years that the average Russian man gets.
