JAMB - Economics (2023 - No. 68)
Which one of the following measures the natural growth rate of population?
Natural increase - Birth rate + Net migration
Birth rate - Death rate
Birth rate/Death rate
Birth + Net migration = Death
Explanation
The natural growth rate of a population is measured by the difference between the birth rate and the death rate. This is because the birth rate indicates the number of births in a population, while the death rate indicates the number of deaths. The difference between these two rates gives the natural increase or decrease in the population, without considering migration.
