About this chart
St. Louis, Missouri, ended 2025 below its 2012 population high: 278,144 residents, compared with 319,534 at the peak. Its city-limit count moved from 319,367 in 2010 to 278,144 in 2025. The largest annual change in the displayed series occurred in 2022: 7,044 fewer residents than the preceding estimate. These estimates describe the incorporated place, rather than its wider metropolitan area.
These figures measure St. Louis within its Census incorporated-place boundaries, not the population of the surrounding metropolitan area. They are July 1 estimates, combining Vintage 2020 for 2010–2019 and Vintage 2025 for 2020 onward. City boundaries can change, and newer Census vintages revise estimates; a shift in this series cannot be attributed to migration alone. Consolidated-city balances exclude separately incorporated places. The table preserves exact resident counts, while the chart follows the annual sequence.
