The age-group pyramid shows males and females separately for each five-year age group. What does this make it, compared with the age-grouped data in a table?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A much more detailed version of the same data
Option (1) A direct measure of the dependency ratio of the population — Incorrect. The dependency ratio is the ratio of the non-working age population to the working-age population. The pyramid shows the numbers by age, but it does not work out this ratio for the reader.
Option (2) A much more detailed version of the same data — Correct. The pyramid shows the same age-grouped data as the table, but it splits each five-year group into males and females. This gives a much more detailed, visual picture of the age structure.
Option (3) A record of the child sex ratio for the 0-6 years age group — Incorrect. The child sex ratio counts girls per thousand boys in the 0-6 years group. The pyramid covers all ages in five-year groups, from 0-4 years up to 80 years and above, so it is not this record.
Option (4) A summary of regional variations in the fertility rate — Incorrect. Regional variation in fertility compares the fertility rates of states such as Kerala and Uttar Pradesh. The age-group pyramid is a different tool: it shows how a population is spread across age groups for males and females.
