Figures from the central bureaus of statistics from three nations, showing the different expected effects of aging.
Whereas the Netherlands will have an almost unchanged absolute amount of people in the ages 0-65, with the biggest decrease of -4.07% per category in the main workforce of 25-44 years old, the amount of elderly will increase with nearly 50%.
The United States will see an absolute increase in population overall, but lowest in the category 25-44 years, which will increase by 7.73%, in sharp contrast to the amount of elderly, which will increase by 104.2%. Instead of 35 million elderly, there are over 70 million elderly expected by 2030.
As for Japan, the increase of elderly is not so high compared to the other countries, with only 21%, however, the other age categories are declining, most notably children by 22.5%.
Main questions to be asked as a government include where will these people live and who will take care of them as their health declines?
