The line chart gives information about the percentage of working age adults in four countries over a period of 60 years starting from 1960 with a prediction from 2030 to 2050. Overall, all countries experienced a decline but the propotion of United States was the highest while the Japan’s was the lowest by the end of the timeframe.
In 1960, the population of working age adults in United States was accounted for 60% of total. It increased rapidly to over 65% in 1980 before fluctuating around that point in 1990 and continued to hit the peak at about 67% in 2000. After that, there was a crash from over 65% to under 65% between 20210 and 2020. It was predicted to contiue to decrease to roughly 62% in 2030 and oscillating around 60% of total in both 2040 and 2050. In contrast, starting at 65% of total in the first year, it went up significantly to reach the highest point at 70% in 1990. But later, there was a plummet to around 65% in 2000 and approximately 64% and 57% in 2010 and 2020. It was projected to fall to a low at 51% in the final year.
Meanwhile, France started at over 60% in 1960 and continued to rise to over 65% before a plateau at around 65% from 1990 to 2010. It declined dramatically to 60% in 2020 and predicted to continued to dropped to just over 55% in the 2050. Besides that, Germany had the highest working age population in four categories at 66% of total in 1960 but Germany witnessed a crash to under 65% in 1970. Despite of a sharp recovery from 1980 to 1990 and reaching to the highest mark at 70% in 1990, it dwindled rapidly to over 60% of total in 2020. And it was projected to reduce to 55% in the end of the timeframe.
