In this article, we will be analyzing the population dynamics in the US and the 15 US cities where the population decreased the most. If you wish to skip our detailed analysis, you can move directly to the 5 US Cities Where Populations Decreased the Most.

Population Dynamics in the US

The United States ranks among the most populous countries worldwide. As reported by the US Census Bureau, the country’s population is 336,167,022, as of March 14. Region-wise, the South accounted for 38.9% of the population growth in 2023. Population growths of 23.6% for the West, 20.6% for the Midwest, and 17% for the Northeast were reported in 2023. Some of the most populous US states include California, Texas, Florida, and New York. You can also take a look at the most densely populated cities in the US.

2022 showed the first signs of US recovery from the global pandemic in terms of population growth. This was when the US population was reported to have increased by 0.4%. The primary driver of this growth was the net international migration which added 1,010,923 people to the national population.

Future prediction represents a slow-paced population growth for the country over the coming years. On November 9, 2023, the US Census Bureau reported that the US population has been forecasted to approach almost 370 million in 2080 before moving downward to 366 million in 2100. It has been projected that immigration will be the largest contributing factor to the US population growth. Simultaneously, a natural decrease in the country’s population will be supported by declining fertility rates and an aging population. The reduced fertility rates will also impact the nation’s age structure, leading to more adults aged 65 and above as compared to children under the age of 18.

Declining Populations: Past Trends and Future Projections

One year into the pandemic, the US Census Bureau reported that some of the fastest-growing US cities during the pre-pandemic period, witnessed slower growth rates after the pandemic. Population growth especially slowed in the cities of Leander in Texas and Meridian in Idaho.

With respect to the fastest declining cities, San Fransisco ranked at the top in 2021 when it was not even a part of the list in 2019. Even for the city of Cupertino which had been a declining city in both 2019 and 2021, the drop in its population growth was almost triple. Overall, six of the top fifteen declining cities were based in California. The largest numeric decrease in population was recorded in New York City, San Fransisco, Chicago, and Los Angeles.

A recent study reveals that almost half of the 30,000 US cities will be subject to depopulation by 2100. This study initially began as a project commissioned by the Illinois Department of Transportation to carry out an analysis of the challenges in transportation that could arise from population changes in Illinois. However, a deeper analysis showed that the biggest population losses will be taking place in the Northeast and Midwest of the country as the population moves to the South and West. States such as Texas and Utah where the population tends to be growing as of now, will be seeing a fair share of their cities undergoing depopulation in the future. The population will also be declining in the cities situated in Illinois, Mississippi, Kansas, New Hampshire, and Michigan. Overall, some sort of depopulation has been forecasted for all US states except for the District of Columbia and Hawaii.
