About this chart

Kansas City leads Missouri with 521,220 residents in 2025, ahead of St. Louis by 243,076. St. Louis has 278,144 people, while Springfield ranks third with 169,847. The ranking uses incorporated-place populations rather than metropolitan areas. Kansas City had 460,690 residents in 2010, so its city-limit count grew by 13.1% over the displayed period. Kansas City was the largest of these places at the start of the series.

The annual Census estimates describe July 1 populations within the boundaries of each incorporated place in Missouri. The series joins Vintage 2020 estimates for 2010–2019 with Vintage 2025 estimates from 2020 onward. Boundary changes and revisions can affect the trend. Unincorporated communities and census-designated places are excluded, and the ranking does not measure the population of the wider urban or commuting region. Every place that entered the annual top ten remains in the chart.
