city with a population above 100,000 to calculate the population density per square mile. To find which cities have the highest and lowest population density, researchers at Filterbuy collected population and land area figures for every U.S. San Francisco, CA and Jacksonville, FL have similar populations at around 900,000 each, but the differences in land area-46.9 square miles for San Francisco versus 747.3 square miles in Jacksonville-make them the second-most and second-least densely populated large city in the U.S., respectively.

Sun Belt states like Arizona, Florida, Nevada, Texas, and the Carolinas could be poised to move up the list as migration-driven population growth continues in these areas.Īs with states, population density in cities depends both on the number of residents and land area. Cities in these long-established states-including Rhode Island, Massachusetts, Connecticut, and Maryland-were the original beneficiaries of the population growth following the Industrial Revolution, and their populations remain densely clustered in urban centers. In terms of overall population density, states in the Mid-Atlantic and New England regions lead the nation, with New Jersey topping the list at more than 1,200 residents per square mile.

If you live in an urban area, it’s important to replace your home air filters frequently. Residents of densely populated cities often endure generally worse air quality composed of many unhealthy pollutants. Across the country, only four states-Mississippi, West Virginia, Vermont, and Maine-have less than half of their population in urban areas. In fact, nine states have more than 90 percent of their population living in urban areas, led by California at 95 percent. But as the fall surge of coronavirus cases in the upper Midwest has shown, even rural communities are not invulnerable from viral spread, and it remains to be seen whether these shifts in living preferences will prove durable even after vaccines are widely available, and the threat of COVID-19 subsides.įor now, urbanization remains the dominant characteristic in many parts of the country outside of New England, the Midwest, and parts of the South. As a result, there are some early indications that urbanites are showing a greater preference for low-density living with more outdoor space. Indeed, some of the worst-hit areas in the pandemic have been dense urban centers, including America’s two largest metros: New York and Los Angeles. The hustle and bustle that gives large, densely-populated cities their character-with large numbers of people from many different places constantly crossing paths and crowding together-also creates the conditions for widespread transmission of viruses like COVID-19. One question now, however, is whether COVID-19 will slow down or reverse that pattern. While many rural areas stagnate or decline, urban areas continue to attract jobs and capital investment. With increasingly divergent economic prospects in urban and rural America, there is good reason to believe that the trend toward city living could continue. In 2010, the share of Americans living in urban areas surpassed 80 percent for the first time. Today, the split of urban and rural Americans looks almost inverted compared to the population distribution of more than two centuries ago. In recent years, trends have pointed toward re-urbanization, with more people leaving the suburbs to return to cities, attracted by the amenities and economic opportunities available in urban centers. As urban areas continued to grow, the post-World War II era also led to heavy growth in suburban areas, with a population boom driven by new births and a building boom driven by mass production techniques that lowered the cost of homeownership.

The onset of the Industrial Revolution in the early- to mid-1800s sparked rapid urbanization as more people left the farms for industrial jobs in growing cities. was a predominantly agrarian, rural society, with only about one in 20 residents living in urban areas.

The story of American history is inextricably intertwined with the story of urbanization.
