About this chart

Boston leads Massachusetts with 672,973 residents in 2025, ahead of Worcester by 459,111. Worcester has 213,862 people, while Springfield ranks third with 154,702. The ranking uses incorporated-place populations rather than metropolitan areas. Boston had 621,053 residents in 2010, so its city-limit count grew by 8.4% over the displayed period. Boston 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 Massachusetts. 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.
