Two Solutions to Aging Population Challenge

Population aging—the increase of the share of older individuals in a society due to fertility declines and rising life expectancy—is an irreversible global trend with far-reaching economic and socio-political consequences. By 2050, the number of people aged 60 and older will more than double from its current levels, reaching around 2 billion. While Europe was the first global region to embark on a demographic transition, most of the expected growth in the number of older people by 2050 will come from developing countries. Population aging will likely lead to declining labor forces, lower fertility, and an increase in the age dependency ratio, the ratio of working-age to old-age individuals. To illustrate, while there were 10 workers for every person older than 64 in the world in 1970, the expected number in 2050 is only four; it will even be less than two in some European countries.
