Frequently Asked Questions
What is the difference between population distribution and population density?
Population distribution refers to the pattern of where people live across a region, whereas population density measures the concentration of people by calculating the number of individuals living per square kilometer.
How do push and pull factors affect migration?
Push factors compel people to leave their homes due to unfavorable conditions like drought or lack of jobs, while pull factors draw migrants to new areas offering better opportunities, safety, and better living standards.
Why is the study of age-sex structure important?
Age-sex structure helps governments understand the proportion of dependents (children and elderly) versus the working-age population, enabling better planning for healthcare, education, employment, and social welfare schemes.
