Physical factors, such as space constraints, land topography, resources, and climate. Human factors, including politics, lifestyle, and economics. Birth rate, death rate, and dispersion. Death and emigration, which tend to decrease population density. Births and immigration, which tend to increase population density. Population density is the average number of people living in a given area. Physical factors, such as space constraints, land topography, resources, and climate can affect population density.
