The correct option is Actual Growth includes migration, while Natural Growth does not..
Explanation
Population change is quantified using two distinct metrics: Natural Growth and Actual Growth. The fundamental difference between these concepts lies in the inclusion or exclusion of migration as a factor of population change.
Analysis of Growth Metrics
- Natural Growth of Population: This refers to the population increase determined exclusively by the difference between births and deaths in a particular region between two points in time. It does not account for the movement of people.
Formula: Natural Growth = Births - Deaths - Actual Growth of Population: This reflects the real change in population size by accounting for both biological factors (births and deaths) and the physical movement of people (migration).
Formula: Actual Growth = (Births - Deaths) + (In Migration - Out Migration)
Therefore, Actual Growth includes migration, whereas Natural Growth is limited to biological increase.
Key Takeaway: Natural Growth is calculated solely based on Births and Deaths, while Actual Growth includes Births, Deaths, and Net Migration.
