A country with a high rate of population growth took measures to reduce it. The figure below shows age-sex pyramids of populations A and B twenty years apart. Select the correct interpretation:
Interpretations:
1) "B" is earlier pyramid and shows stabilised growth rate.
2) "B" is more recent showing that population is very young.
3) "A" is the earlier pyramid and no change has occurred in the growth rate.
4) "A" is more recent and shows slight reduction in the growth rate.
- A"B" is earlier pyramid and shows stabilised growth rate.
- B"B" is more recent showing that population is very young.
- C"A" is the earlier pyramid and no change has occurred in the growth rate.
- D"A" is more recent and shows slight reduction in the growth rate.
Solution & Step-by-step Explanation
In population pyramids, a broader base indicates a higher proportion of young individuals (expanding population). A narrowing base in the more recent pyramid (A) compared to an earlier one (B) indicates a reduction in birth rates and thus a successful growth reduction strategy.
