Frequently Asked Questions
Why is population considered a resource?
Population is considered a ultimate resource because human beings use their skills, knowledge, and labor to develop the country's other resources and drive economic progress.
What is the difference between birth rate and death rate?
Birth rate is the number of live births per 1,000 people in a year, which increases population, while death rate is the number of deaths per 1,000 people in a year, which decreases population.
Why is the population density high in plain regions?
Plains have fertile soil for agriculture, flat land for building transport and houses, and availability of water, which makes it easier for people to live and work there.
