Physical Factors: Physical factors include temperature, rainfall, soil, relief, water, natural vegetation, distribution of minerals and availability of energy resources.
Historical Factors: Regions with historical importance (river valley civilizations), war and constant invasions fall under historical factors responsible for population distribution.
Economic Factors: Educational institutions, employment opportunities, manufacturing industries, luxurious amenities, trade and commerce and other facilities encourage dense population in an area.
