Question
Population pyramid and sex ratio.
✓
Answer
- The ratio between the number of male and female in the population is called sex ratio.
- Sex ratio is an indicator of status of women in the country.
- In population pyramid X-axis shows the percentage of population in a particular age group and Y-axis, which is at the centre of the graph shows age groups.
- The length of the bar shows number or percentage.
- The left side of the graph shows male population whereas, the right side of the graph shows female population.
- Thus, population pyramid indicates number of percentages of male and female population in different age groups in the country.
e.g., If we want to know the percentage of male and female in 15-59 age group, we can get it from population pyramid. - Therefore, we can study age-wise sex ratio using population pyramid.
