What challenges arise from high population density in urban areas?
Challenges include urban sprawl, limited resources, and potential overstretching of infrastructure and services.
What is the difference between arithmetic density and physiological density?
Arithmetic density is the total population divided by total land area, while physiological density is the population divided by arable land.
What characterizes Stage 2 of the Demographic Transition Model?
Stage 2 is marked by high birth rates and rapidly declining death rates, leading to significant population growth.
Discuss the implications of the dependency ratio on a nation's economy.
