The St. Louis region lost more than 3,200 residents in the year ended July 1, 2023, and was surpassed by both Charlotte and Orlando, making it the 23rd-largest U.S. metro by population, down from No. 21, according to new U.S. Census Bureau estimates.
While expected, the new figures underscore the area's economic challenges, according to a researcher who studies the data.
"There are always economic consequences to a population that's aging," said Ness Sandoval, professor of sociology at Saint Louis University. He's cited data showing that despite St. Louis posting healthy gross domestic product growth in 2022, it was surpassed for the measurement by Tampa and Austin, making St. Louis the 24th-largest metro for GDP. "The regional GDP is being impacted by population growth," Sandoval said.
The Census Bureau reported that the St. Louis region had a population of 2,796,999 in 2023, down from 2,800,245 in 2022, 2,812,587 in 2021 and 2,819,212 in 2020. In 2010, the agency said St. Louis had 2,787,701 residents.
The St. Louis region from 2022 to 2023 saw 1,517 more deaths than births, the agency said.
It also saw negative migration of 1,747; international migration totaled 3,856, but domestic migration was -5,603.
From 2022 to 2023, the Census Bureau said Charlotte gained 50,458 residents, for a new population of 2,805,115. Orlando gained 54,916, ending at 2,817,933.
Growing San Antonio (population 2,703,999) and Austin (2,473,275) could next pass St. Louis, Sandoval said.
The city of St. Louis and St. Louis County continued to lose residents.
The city lost 4,439 residents, or 1.5%, ending with 281,754 as of July 1. That means it has lost more than 37,000 residents since 2011, according to Census figures, with a loss of more than 18,000 since 2019.
St. Louis County lost 3,732, ending at 987,059. The county is smaller than in 1990, when it counted 993,508 residents.
The region's major Illinois counties also lost residents, with Madison down 820, to 262,752, and St. Clair off 1,247, to 251,018.
Gaining in Missouri were St. Charles County, up 2,861 to 416,659; Jefferson County, up 2,010 to 231,230; Lincoln County, up 1,517 to 64,699; and Warren County, up 516 to 37,806.
Greater St. Louis Inc., the region's primary business group, said in a statement that the new figures were expected and "affirm the reason" it was created three years ago.
"We have to up our game here in order to win this decade," it said. "In any given year, population data like this will ebb and flow, which is why it is imperative that we maintain our focus on and commitment to growth in the long term."
The group said it has set "ambitious targets and a plan of action to grow St. Louis by 2030," and is seeing "positive momentum."
It cited the 2022 GDP figure, plus a report from Site Selection Magazine that St. Louis tops a ranking of all metros along the Mississippi River for total number of corporate facility investment projects, for the period from July 2022 to December 2023. And it pointed to U.S. Bureau of Labor Statistics data showing that the region added nearly 25,000 new jobs last year.
"These major economic wins show that by working together as a metro and speaking with a unified voice, we are winning," Greater St. Louis said. "But there is still much work to do to get our population growing, and we must continue to act with urgency to win this decade and reverse these trends by 2030."
The Census Bureau, in a news release, said that in 2023, counties in the South saw faster growth and more Northeast and Midwest counties had population losses turn to gains. Sixty percent of U.S. counties gained population, up from 52% between 2021 and 2022. All U.S. counties averaged a 0.29% gain, up from 0.17%.
About 73% of U.S. metro areas grew from 2022 to 2023, it said.
"Areas which experienced high levels of domestic out-migration during the pandemic, such as in the Midwest and Northeast, are now seeing more counties with population growth," Lauren Bowers, chief of the Census Bureau's population estimates branch, said in the release. "Meanwhile, county population growth is slowing down out west, such as in Arizona and Idaho."
The Census Bureau said that of counties with population above 20,000, Randolph County, Missouri, some 40 miles north of Columbia, saw the second-steepest decline, at -2.1%. The Census Bureau previously said that for the year ended July 1, 2023, Missouri added a modest 18,988 residents, while Illinois lost 32,826. Kansas City added more than 12,000 residents during the period, to 2,221,343.
