Updated On: Nov 12, 2026
- Natality and Mortality
- Natality and Emigration
- Mortality and Immigration
- Natality and Immigration
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Population density changes through four processes: natality, mortality, immigration and emigration.
Step 2: Increase factors
Natality (births) and immigration (individuals coming in from outside) add to the population.
Step 3: Decrease factors
Mortality (deaths) and emigration (individuals leaving) reduce the population.
Step 4: Conclusion
Natality and immigration increase the population density.
Final Answer:
Natality and immigration increase population density. \[ \boxed{\text{(D) }\text{Natality and Immigration}} \]
