As a population ages, the potential support ratio tends to fall. Between 1950 and 2009, the potential ratio declined from 12 to 9 potential workers per person aged 65 or over. By 2050, the potential support ratio is projected to drop further to reach 4 potential worker per older person. The reduction of potential support ratio has important implications for social security schemes, particularly for pay-as-you-go pension systems under which taxes on current workers pay the pensions of retirees.
In 2015, Japan has the lowest PSR in the world, at 1.8.World Population Prospects
