| BLUF: Blue cities will continue the trend of driving away legal residents, while cities in red states will continue to gain. |
"Close to half of the nearly 30,000 cities in the United States will face some sort of population decline," researchers from the University of Chicago in Illinois wrote in a journal article published in Nature Cities.
Major cities in the Northeast and Midwest are already slowly losing population. While cities in the South and West regions are experiencing a population increase, some major cities in Alabama, Georgia and Tennessee are slowly depopulating, the researchers found.
Cleveland, Buffalo, and Pittsburgh could see depopulation of 12 to 23 percent by 2100 while cities like Louisville, New Haven and Syracuse -- not currently showing declines - likely could soon.
"You might see a lot of growth in Texas right now, but if you had looked at Michigan 100 years ago, you probably would have thought that Detroit would be the largest city in the U.S. now," Sybil Derrible, one of the researchers, told Scientific American.
The study briefly looked at possible causes for these population changes, from the effects of an aging population to changes in the economy, wages and access to transportation -- as well as things like climate change and similar factors.
"In the Northeast and Midwest, urban cities with lower median household income are more likely to experience depopulation over time," the study authors wrote.
"Such trends could exacerbate socioeconomic challenges experienced by lower-income households in these regions, given that population decline can create affordability concerns with infrastructure services."
