A population pyramid with big base and skinny top shows:

(a) High birth rates

(b) High death rates in higher age group

(c) Relatively large number of young population

(d) Large number of deaths of infants

Choose the correct option:

The correct answer is:  Only (a), (b) and (c)

A population pyramid with big base and skinny top shows high birth rates, high death rates in higher age groups, and a relatively large number of young population.

Key Points

• High birth rates:
  • The wide base of the population pyramid indicates a high number of births, suggesting high birth rates.
• High death rates in higher age groups:
  • The skinny top of the pyramid signifies that fewer people survive to older ages, indicating higher death rates in higher age groups.
• Relatively large number of young population:
  • The broad base also suggests a large proportion of the population is young, showing a demographic trend towards a younger population.

Additional Information

• Large number of deaths of infants:
  • This option is incorrect as a wide base indicates high birth rates, not necessarily high infant mortality. While there may be some infant deaths, the primary indicator here is the high birth rate.
