The Kansas City metro area continues to grow, while the St. Louis metro area lost population in the last year.
The St. Louis metro’s population declined by 1,328 from 2015 to 2016, according to the latest migration estimates from the U.S. Census Bureau. Its natural population growth — more births than deaths — was positive at 6,633, but its net migration was a negative 7,403 — 11,583 domestic migrants left, and 4,180 international migrants arrived.
And for the first time since 2011, St. Louis County, which covers several outlying cities around the city of St. Louis, dropped below 1 million people, largely because of a rise in net domestic out-migration.
Meanwhile, the Kansas City metro area experienced modest growth, said Jeff Pinkerton, senior researcher at the Mid-America Regional Council, the planning organization for greater Kansas City.
The seven-county Kansas City area grew by about 19,900 from 2015 to 2016. About half of that was natural population growth, and the rest was net migration, Pinkerton said.
Since 2010, the Kansas City metro area has added about 97,000 people.
