Last week, the U.S. Census Bureau released new population estimates for U.S. Metropolitan Statistical Areas (MSAs), showing that the St. Louis MSA had a population of 2.8 million in 2018 and was the 20th most populous MSA in the country. In 2017 , the Census Bureau had estimated that the St. Louis population slipped from the 20th to the 21st most populous MSA in the country.
Since 2010, St. Louis’ population has grown by around 17,000 people (0.6 percent), but the region’s population growth has slowed in recent years. Among the 50 most populous U.S. regions (which are referred to as the peer regions), St. Louis was one of eight to lose population last year. Between 2017 and 2018, St. Louis’ population declined slightly by -0.01 percent (385 people), a rate of change that ranks 44th out of the 50 peer regions.
This decrease in population was largely due to domestic out-migration. Between 2017 and 2018, St. Louis saw a greater number of births than deaths, resulting in an increase of 4,887 people due to natural changes. The region also experienced a net increase of 4,242 people due to international migration, but these gains were offset by a net decrease of 9,471 people due to domestic out-migration (people moving to other parts of the country).
Within the 15-county area, St. Charles and Lincoln counties experienced the greatest increases in population, adding 3,937 and 1,552 people to their population totals, respectively. The city of St. Louis and St. Clair County experienced the greatest losses in population, with decreases of 5,028 and 1,367 people, respectively.
