If life expectancy continues to rise, which age group's share may increase?

Answer and explanation

Correct answer: Elderly age group

Life expectancy is the average number of years that people are expected to live under prevailing mortality conditions. When it rises, a larger share of the population survives into later ages. This does not mean that every age group must increase, but it makes an increase in the proportion of elderly people possible, especially when people live longer and fertility is low.

Thus, option A, the elderly age group, is correct. Longer life can gradually change the age structure by increasing the number of people at older ages. The information does not support the claim that only newborns, adolescents, or people aged 15 to 20 will increase. Those groups depend mainly on births, survival patterns at younger ages, and migration. Rising life expectancy particularly has a direct effect on survival to old age.
