Growth rate of the population is the difference between the birth rate and the death rate. As long as the birth rate exceeds the death rate, the population grows. If the birth rate is lower than the death rate, the population declines.

The Apt Definition for Natural Growth Rate:
The apt definition for natural growth rate is option 'A', which is the difference between the birth rate and the death rate of a country. This definition accurately captures the concept of natural growth rate, which represents the rate at which a population increases or decreases due to births and deaths alone, without considering migration.
Explanation:
Natural growth rate is an important demographic indicator that helps us understand the population dynamics of a country. It provides insights into the overall population change and can have significant implications for various social, economic, and environmental factors.
Here is a detailed explanation of why option 'A' is the correct definition for natural growth rate:
1. Birth Rate:
The birth rate refers to the number of live births per thousand individuals in a population over a specific period. It represents the fertility level of a country and indicates the number of new individuals being added to the population through births.
2. Death Rate:
The death rate, also known as the mortality rate, represents the number of deaths per thousand individuals in a population over a specific period. It reflects the mortality level of a country and indicates the number of individuals leaving the population through deaths.
3. Natural Growth Rate:
The natural growth rate is derived by subtracting the death rate from the birth rate. It provides a measure of the population change resulting from natural processes, specifically births and deaths. A positive natural growth rate indicates that births exceed deaths, resulting in population growth, while a negative natural growth rate indicates that deaths exceed births, resulting in population decline.
4. Exclusion of Migration:
The natural growth rate focuses solely on the difference between births and deaths and does not consider the impact of migration. Migration refers to the movement of individuals into or out of a country, which can significantly affect the overall population change. By excluding migration, the natural growth rate provides a clear and specific measure of population change resulting from births and deaths alone.
Conclusion:
In summary, the apt definition for natural growth rate is the difference between the birth rate and the death rate of a country. This definition accurately captures the concept by focusing on the population change resulting from births and deaths without considering migration. Understanding the natural growth rate is crucial for policymakers, researchers, and demographers to analyze population trends, plan for the future, and address various social and economic challenges.
