How does the age pyramid's structure change depending on fertility and mortality rates?
High fertility rates and low mortality rates result in a pyramid with a broad base and a wide top.
High fertility and mortality rates result in a pyramid with a broad base and a narrow top.
Low fertility rates and high mortality rates result in a pyramid with a narrow base and a broad top.
Low fertility and mortality rates result in a pyramid with a narrow base and a narrow top.
Answers (1)
Correct option (a)
The age pyramid's shape can be considerably influenced by mortality and fertility rates.
The number of live births per 1,000 women of reproductive age is a common way to estimate fertility rates, which refer to the number of children born to women of childbearing age in a population.
The term "mortality rate" refers to the number of deaths in a population, which is commonly expressed as the death rate per 1,000 people.
The number of children in the younger age groups will be higher in a society with high fertility rates and low mortality rates, creating a pyramid with a broad base.
The number of people in each age group steadily declines as these people get older and migrate into older age groups, resulting in a smaller top.
On the other hand, a population with low rates of both fertility and mortality will have fewer children in the lower age groups, creating a pyramid with a narrower base.
The proportion of people in each age group may be more evenly distributed as these people get older and transition into older age groups, which would lead to a less obvious narrowing at the top.
Option a is the correct answer.
