Three demographic measures that often closely parallel each other in terms of global distribution are:
-
Population Density: This measures the number of people living per unit area (such as per square kilometer or square mile). Regions with high population density often have similar social, economic, and environmental characteristics.
-
Urbanization Rate: This refers to the percentage of a population that lives in urban areas compared to rural areas. Higher urbanization rates are typically found in regions with high population density, as people concentrate in cities for economic opportunities and better access to services.
-
GDP Per Capita: This is an economic measure that divides the country's gross domestic product by its total population. Regions with higher GDP per capita often correlate with high population density and urbanization rates, as urban areas usually provide better job opportunities, infrastructure, and services that contribute to economic prosperity.
These three measures are interconnected and often reflect similar trends in demographic and economic development across different regions of the world.
