Overall, the trends show fluctuations in the proportion of working-age adults in each country over the years.
France experienced a gradual increase in its working-age population, starting at around 60% in 1960 and rising steadily to approximately 65% by 2015. In contrast, the United States began at a similar level to France in 1960 but there were fluctuations over the years, with a slight decline around the mid-1980s before staying stable close to its initial percentage by 2015.
Japan started with a lower proportion of working-age adults compared to France and the United States in 1960. However, it displayed a consistent upward trend, reaching a similar percentage to France at 2015.Germany’s trajectory was distinct, starting at a relatively high percentage in 1960, then declining until the early 1980s, before gradually increasing again to approximately 65% by 2015, mirroring France’s final figure.
