...Russia and Japan are expected to have REVERSED population growth...
Both Russia and Japan have seen a higher proportion of their aging population as opposed to a young population.
This has led to estimates that there will be reversed population growth in these countries which means that the population will fall. In Japan this is particularly serious with 33% of the population above 60 years of age.
Should this trend continue, when those older people eventually pass on they will not be adequately replaced by the younger generation leading to a reduction in population.
