Final answer:
The number of older people in less developed countries is projected to increase more than in developed countries.
Step-by-step explanation:
The statement is true. The number of older people in less developed countries is projected to increase more than in developed countries.
According to the given information, high-income nations are expected to have a larger share of elderly population by 2020 or so. On the other hand, most low-income countries still have a higher proportion of youth and young adults, but by about 2050, their elderly populations are also expected to increase significantly.
These demographic changes will have considerable impact on the standard of living of the young and the old in both developed and undeveloped countries.
