US POPULATION DENSITY MAP BY SQUARE MILE ARCHIVE

One of the Distributed Active Archive Centers in NASA’s Earth Observing System Data and Information System, SEDAC provides information about human interactions in the environment. This particular population density map is based on a global population density map created at the Socioeconomic Data and Applications Center (SEDAC) at Columbia University. In the comparison, trends that track the human footprint can emerge. How does population density relate to changes in land cover? How are natural resources distributed in relation to population? How do densely populated regions, with their pollution, artificial surfaces, and urban heat islands, affect climate? To answer these and other questions, scientists compare detailed population maps to other geographically based data sets, including satellite data. Other large western cities readily visible here include Portland, Seattle, Phoenix, and Denver.įor Earth scientists, population density maps can be crucial in answering questions about the relationship between people and the environment. Like their counterparts in the east, the largest cities in the west (San Diego and Los Angeles in the south San Francisco, Oakland, and San Jose farther north) hug the coast, with the densest populations in Southern California. The west remains lightly populated except for clearly defined urban regions. Other cities-Atlanta, Chicago, Houston, and Dallas-punctuate the map in the country’s interior. Experts can use this information to inform decisions around resource al location, natural disaster relief, and new infrastructure projects.

Understanding and mapping population density is important. Rings of decreasing population density radiate out from the major urban centers of New York, Philadelphia, and Washington along the East Coast. Population density is the average number of people per unit, usually miles or kilometers, of land area. Where are all of these people living? This map, based on population estimates made in 2005, charts out the number of people in every square kilometer of the United States.Īs has been the case historically, the most densely populated parts of the United States are east of the Mississippi River. The Chinese territory of Macau has the world's 2nd highest population density at 22,005/km. km (62,849/sq mile), and its population only numbers in thousands. With one birth every 7 seconds, a death every 13 seconds, and a migrant entering the country every 31 seconds, the United States’ population is growing at a rate of one person every 11 seconds. The European city-state of Monaco is the most densely populated country with a population density of 24,266 people per sq. Larger map markers shown below represent cities spanning greater land areas.The population of the United States reached 300 million on October 17, 2006, said the U.S. The area is calculated from the geometry of the geographic feature in projected coordinates.

It is calculated by dividing the total population count of geographic feature by the area of the feature, in square miles. Plotting each jurisdiction's land area illustrates just how many of the nation's largest cities are scattered throughout the South and western region. Population density is the number of people per square mile. ( Click to open full-screen interactive map in new window) population densities, expressed as people per square mile, are: State. Here's a map of the 200 most populous cities and other Census-designated places, with the most dense shown in dark blue. Color Scheme: Blues, Purple Red, Viridis, Yellow Green, Yellow Green Blue. Of the 100 most populous cities, the following had the highest population density (shown in persons/square mile) in 2010: The density of these cities pales in comparison to the more urban population centers along the coasts.

mile and San Antonio (seventh most populous) with 2,880 people/sq. Similar cities include Phoenix (sixth most populous nationally) with a population density of 2,798 people/sq.
