In the U.S., population density is typically expressed as the number of people per square mile of land area. While a useful tool for decision and policymakers, it is important to understand the limitations of population density. Infectious disease scientists use these maps to understand the spread of infectious disease, a topic that has become critical after the COVID-19 global pandemic. Experts can use this information to inform decisions around resource allocation, natural disaster relief, and new infrastructure projects. ![]() Understanding and mapping population density is important. ![]() Population density is the average number of people per unit, usually miles or kilometers, of land area. In relation to the equator it is seen that the vast majority of human population lives in the Northern Hemisphere, where 67 of Earths land area is. This has resulted in an increase in population density for these cities, which are now forced to expand in order to accommodate the growing population. Population density (people per square kilometre) by country in 2023 Population density (people per square kilometre) map of the world in 1994.
