About this chart

Boston, Massachusetts, had a city-limit count 51,920 higher in 2025 than in 2010, a 8.4% change. The latest Census estimate is 672,973 people within city limits, ranking 25 among US incorporated places. The displayed series peaked at 694,661 in 2019, above the latest count. The biggest annual change occurred in 2020: 24,996 fewer residents than the preceding estimate. This coincides with the change in Census vintages.

These figures measure Boston 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.
