Question

If a population's age structure diagram looks like a pyramid, the population:

a) is expanding.
b) is shrinking.
c) is remaining the same.
d) will expand for at least a generation.
e) is showing continuous exponential growth.

Answer 1

A population's age structure diagram that looks like a pyramid suggests that the population is expanding, characteristic of a rapid growth stage mainly seen in less economically developed countries. The correct option is A.

Step-by-step explanation:

If a population's age structure diagram looks like a pyramid, the population is expanding. The pyramid-shaped age structure diagram is characteristic of Stage 1, which indicates rapid growth.

This shape suggests a large base of younger individuals, many of whom are or will soon be of reproductive age, with the number of individuals decreasing rapidly with age at each higher age bracket. The pyramidal shape is usually seen in less economically developed countries where there's a high birth rate and often a shorter life expectancy.
