Solution
The relative proportion of individuals of various age groups in the population is called the age structure of the population.
Role of age structure:
Age structure (distribution of age groups) determines the trend of the population.
- Growing population: The population having a larger number of individuals of the pre-reproductive age groups shows a very rapid rate of growth.
- Steady population: Population having the same number of pre-reproductive and post-reproductive age groups is stable.
- Declining population: A large number of post-reproductive and a small number of pre-reproductive groups make the population decline.
