• B. Japan will have a much more significant proportion of young people in comparison with its older population.
• C. In the 75-79 age bracket, there will be more males than females in Japan's population.
• D. Japan will have a lot more older people than working-age people or children.

Answer 1

The correct option is D Japan will have a lot more older people than working-age people or children.

In a population pyramid, bars stacked on one another represent the age category. The length of the bars represents the percentage of individuals in the specific age group.

The bars on the right side of the central axis represent the female side and that on the left represents the male side.
The broader any part of the pyramid, the more is the proportion of that section of population in the overall population.

In this pyramid, a relatively narrow base means that the population will have a lower proportion of young people and a broader top indicates a relatively larger proportion of older people.
