10 Most Densely Populated Cities in the US (2024 Update)

New york

Population density measures the number of persons per square mile. While it sometimes goes hand in hand with the total number of people, it isn’t always the case, as you’ll soon see. Many of the largest cities have one or more rings of suburbs, which can skew the figures. Our guide looks at the raw numbers, regardless of the stats.

Population density offers insights into urban planning, services, and other fields. Remember that it captures a moment in time. Cities may annex new properties, and, of course, people may move in and out of an area. To put our data in context, the current population density for the United States is 93.8 persons per square mile.

Factors Influencing Population Density

You may have noticed the cities with the highest population densities are located on a coast or a major water body. According to the NOAA Office for Coastal Management, nearly 40% of Americans live on coastline property. It’s understandable with the undoubtedly stunning views they enjoy. Perhaps we’re drawn to these places because of the necessity of water for survival.

Nevertheless, this preference means the population density is over five times the average figure. This concentration of people puts an enormous environmental strain on the land with far-reaching consequences. That’s saying nothing about the infrastructure needs and the social implications. However, enjoying a water view isn’t the only reason Americans move.

The Pandemic

The pandemic had unimaginable consequences that seemed to morph and grow every day. One of the most significant was the rise of remote work. About 71% of employees who could do their job from home did so. A funny thing happened when this shift occurred. People realized they didn’t have to live in big cities anymore. As long as they had Internet access, they could work remotely.

The biggest spikes in population and, thus, density occurred in smaller towns, with larger cities losing residents. People began moving to states with lower population densities, such as Texas, Arizona, and Florida. What will be interesting is to update this article with the next round of census data and see how the changes played out in the country’s population.

Population density is a helpful figure you should keep on your radar if you plan to move. It can tell you the lineup of services you can expect, along with insights into housing costs. Bigger isn’t always better, as many people found out in the aftermath of the pandemic. It was a hard lesson many learned that could have profound implications for future development.
