State and local governments work with NOAA’s Office for Coastal Management to effectively manage coastal areas with the goals of providing public access for recreation, maintaining water quality, protecting the coastal population, preserving important habitats, and encouraging economic development. These include increased risks from high-tide flooding, hurricanes, sea level rise, erosion, and climate change. If you don’t see your city on either top 10 list below, you can look for it on the full list of 50 most crowded cities or their 50 least crowded counterparts. This means that issues that affect the coasts affect a large proportion of Americans.Ĭoastal communities also face different issues than inland communities. (February 2022) Population tables of U.S. Which countries are most densely populated Hannah Ritchie and Edouard Mathieu. Pictured here: The Northeast Corridor as a density bar. This map depicts the population density of world cities in stunning detail. as a whole population density is over five times greater in coastal shoreline counties than the U.S. Source with major processing by Our World in Data. This layer shows the population density in the United States in 2020 in persons per square mile in a multiscale map by country, state, county, ZIP Code, tract, and block group. By Audrey Wachs Decem International, Media. Coastal areas are also far more crowded than the U.S. population, coastal areas account for less than 10% of the total land in the contiguous United States. marine economy is fueled by tourism and recreation, offshore energy, shipbuilding, and aquaculture, to name just a few. would rank third in the world in gross domestic product, beaten only by China and the U.S. If they were their own nation, the coastal counties of the U.S. That’s as much as the entire population of Japan. Population density in the United States is generally lower than in other countries.In the U.S., 127 million people live in coastal counties. The last US census was in 2010, so current figures are projected based on the latest estimates. This is due to its current growth rate of 1.80, which ranks 3rd in the country. Population densities are higher near coastal areas because people prefer living near bodies of water. Texas is the largest of the 48 contiguous US states and sits in the South Central part of the country along the US- Mexico border. Population densities in the United States are higher near major cities. Which option best summarizes the spatial information on this GIS map?Īreas of dense population are randomly distributed in the United States. The Pacific Ocean, Gulf of Mexico, and Atlantic Ocean are labeled. Others are in Texas, Illinois, Georgia, and the New York City area. The darkest shading, indicating 2,000 or greater, appears in only a few small places on the map, the largest of which is in the Los Angeles region. These appear in the San Francisco area, one in Utah, a few in the Midwest and Texas, New Jersey and New York, and Florida. Scattered across the country is the next highest population group, 1000 to 1,999.9. This second group is much denser in the eastern third of the country, with the exception of northern New England. Interestingly, more than 93 of China’s population lives in the Eastern half of the country. The cities of Chengdu and Chonqing, in the Sichuan Basin, are part of a massive population center. There are clusters of the next highest group, 100 to 999.9, in Washington, central and southern California and Arizona, and across the Midwest. Most people are familiar with the large density centers around Hong Kong, Guangzhou, and Shanghai, but the concentration in central China is surprising. The northern and western states show the lightest shading, indicating the lowest population per square mile. The key shows four squares, shaded from dark to light, with the following labels: 2,000 or greater, 1,000 to 1,999.9, 100 to 999.9, and 0 to 99.9. Each county is shaded according to the Key, titled Population per square mile. There are also some pockets of high population density in. The map shows that the eastern and western coasts, as well as some major cities, have higher population densities than other areas of the country. The map includes all state and county border outlines, but they are not labeled. The US population density map uses color-coding to indicate population density, with darker colors representing higher population density. Spatial distribution of population density in the United StatesĪ map of the United States illustrates population density on the county level.Population density in the United States.
