Population Density, Selected Cities, 1960-2020

Population Density, Selected Cities, 1960-2020

Density, measured in people per square km, has substantially declined in major metropolitan areas. The period between 1960 and 2020 was characterized by a process of suburbanization and in many cases the expansion of the metropolitan statistical area. While densification can be observed in many urban areas, at the aggregate level of a metropolitan area lower densities are observed.
