What shows the size of different age groups in a population?
A population pyramid is a way to visualize two variables: age and sex. They are used by demographers, who study populations. A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population.

Which is an example of the age structure of a population?
Age Structure: The age structure of a population refers to the number of people in different age groups. A larger size of population in the age group of 15-59 years indicates the chances of having a larger working population. On the other hand, if the number of children in the population is high, the dependency ratio will be high.
How is the dependency ratio related to age structure?
