Question
Which of the following shows the variation in the population of the male and female with age?
- Sex ratio
- Mortality
- Population pyramid
- Natality
Hint:
Population pyramid shows the variation in the population of the male and female with age
The correct answer is: Population pyramid
- Population pyramid helps in depicting the sex-age structure of the population of a particular area.
- The left side of the pyramid denotes male and right side is female with percentage of years.
- The male side is blue in colour and female side is pink in colour.
