About this chart

San Diego, California, had a city-limit count 100,474 higher in 2025 than in 2010, a 7.7% change. The latest Census estimate is 1,406,106 people within city limits, ranking 8 among US incorporated places. The displayed series peaked at 1,420,200 in 2019, above the latest count. The biggest annual change occurred in 2020: 37,634 fewer residents than the preceding estimate. This coincides with the change in Census vintages.

These figures measure San Diego 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.
