Highest Density Countries
Population density — people per square kilometer — reflects how intensively land is occupied. Small island nations and city-states often top this list, while large continental countries with significant uninhabitable terrain (deserts, mountains, permafrost) register low densities despite large total populations. High density correlates with urban infrastructure demands, housing costs, and environmental pressure. Understanding density alongside total population provides a richer picture of how countries use their territory.
