Answer:
The age structure of a population is the distribution of people of various ages. It is a useful tool for social scientists, public health and health care experts, policy analysts, and policy-makers because it illustrates population trends like rates of births and deaths.
They have a host of social and economic implications in society, like understanding the resources that must be allocated for child care, schooling, and health care, and the familial and greater social implications of whether there are more children or elderly in society.
In graphic form, age structure is portrayed as an age pyramid that shows the youngest age cohort at the bottom, with each additional layer showing the next oldest cohort. Typically males are indicated on the left and females on the right.
Concepts and Implications
Both age structure and age pyramids can take a variety of forms, depending on the birth and death trends within the population, as well as a host of other social factors.
They can be:
stable: patterns of birth and death are unchanging over time
stationary: both low birth and death rates (they slope gently inward and have a rounded top)
expansive: slope dramatically inward and upward from the base, indicating that a population has both high birth and death rates
constrictive: signaling low birth and death rates, and expanding outward from the base before sloping inward to achieve a rounded peak at the top
