About this chart

Seattle, Washington, had a city-limit count 174,123 higher in 2025 than in 2010, a 28.5% change. The latest Census estimate is 784,777 people within city limits, ranking 18 among US incorporated places. The 2025 count is the highest in this displayed series, compared with 610,654 at its start. The biggest annual change occurred in 2016: 22,440 more residents than the preceding estimate.

These figures measure Seattle 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.
