Question

The natural growth of population can be calculated as

• A. Death rate - Birth rate
• B. Birth rate - In-migration
• C. In-migration - Death rate
• D. Birth rate - Death rate

Hint:

Remember: Natural population growth considers only births and deaths. Migration (immigration or emigration) is included only when calculating total population change.

Answer 1

The Correct Option is D

Natural population growth refers to the increase in population that occurs when the number of births in a population exceeds the number of deaths. It only considers natural factors and does not include migration.

The natural increase or natural growth of population is calculated using the following formula: Natural Growth = Birth Rate - Death Rate This formula measures how much the population increases due to natural causes.


• (A) Death rate - Birth rate:
Incorrect. This would give a negative value for growing populations.
• (B) Birth rate - In-migration:
Incorrect. Migration is not included in natural growth calculations.
• (C) In-migration - Death rate:
Incorrect. Migration is not part of natural increase.
• (D) Birth rate - Death rate:
Correct. This is the standard formula used to calculate natural population growth. Natural growth of population is determined by subtracting the death rate from the birth rate. Final Answer:
Birth rate - Death rate.
