![]() Use this map to explore the estimated global population density (people per square kilometer) in 2020. This means urban areas could appear to have fewer people than they really do, while rural areas would seem to have more. This page features files containing county population estimates by demographic characteristics for years 2020 to 2022. All of these areas have a vastly different population density, but they are averaged together. Whereas at a larger scale, such as the state, region, or province level, population density could vary widely as it includes a mix of urban, suburban, and rural places. From 2010 to 2018, the total United States population increased by 6 from 308,745,538 to 327,167,434. Population density is most effective in small- scale places-cities or neighborhoods-where people are evenly distributed. While a useful tool for decision and policymakers, it is important to understand the limitations of population density. The United States of America has a population density of 36/km², which is. For example, Russia has a population density of just 9/km², while Canada is even lower at 4/km². 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. On the other end of the spectrum, some of the largest countries in the world by land area have quite low population densities. Experts can use this information to inform decisions around resource allocation, natural disaster relief, and new infrastructure projects. Explore, customize, and download Census data tables, maps, charts, profiles, and microdata. Understanding and mapping population density is important. Learn about Americas People, Places, and Economy on the official United States Census Bureau data platform. In a broad sense, this number tells us how many people would live within one square mile if. As of 2021, the population density for the United Kingdom was 276 people per square kilometer, with London having by far the highest number of people per. population (316 million in 2013) by the total U.S. Least densely populated county Population density Most densely populated county Population density Alabama: Wilcox County: 13.13/sq mi (5. value is calculated by dividing the total U.S. ![]() Population density is the average number of people per unit, usually miles or kilometers, of land area. In the U.S., population density is typically expressed as the number of people per square mile of land area. 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. Job opportunities in large cities have caused an influx of people to these already packed locations. In the last century, the global population has increased by billions of people.
