What is age structure simple definition?
Definition English: The age structure of a population is the distribution of people among various ages. In graphic form, age structure is portrayed as an age pyramid whose relatively broad base indicates the number of children while the peak reflects the increasing likelihood of death as people age.
What are the 3 types of age structure diagrams?
There are generally three types of population pyramids created from age-sex distributions– expansive, constrictive and stationary.
What can you tell from an age structure diagram?
An age-structure diagram provides a snapshot of the current population and can represent information about the past and give potential clues about future problems. When you are interpreting age-structure diagrams, it is important to compare the width of the base to the rest of the population.
What is the significance of the age structure?
Answer : Age structure represents the number of people of different age groups. It is an important indicator of population composition as it represents the distribution of the population based on age, which further helps in gauging the trend of the population.
Why is the study of age structure important?
The study of age structure plays a very important role in demographic statistics. The study of age structure indices helps to plan for the development of the economic and cultural life of the society.
What is the purpose of age structure?
Age structure data allow the rate of growth (or decline) to be associated with a population's level of economic development. For example, the population of a country with rapid growth has a triangle-shaped age structure with a greater proportion of younger individuals who are at or close to reproductive age.

How does age structure affect population growth?
The age structure of a population is an important factor in population dynamics. Age structure is the proportion of a population at different age ranges. Age structure allows better prediction of population growth, plus the ability to associate this growth with the level of economic development in the region.
Why is age structure important in population growth?
The age structure of a population is an important factor in population dynamics. Age structure is the proportion of a population at different age ranges. Age structure allows better prediction of population growth, plus the ability to associate this growth with the level of economic development in the region.
How does age structure affect the population?
Age structure data allow the rate of growth (or decline) to be associated with a population's level of economic development. For example, the population of a country with rapid growth has a triangle-shaped age structure with a greater proportion of younger individuals who are at or close to reproductive age.
How do age structure diagrams predict the growth of a population?
Age-structure diagrams show the age and gender groups in a population. This allows demographers to predict the future population growth by determining the percentage of the female population. Since females are able to reproduce, demographers can predict the birth rate in the future.
