About this chart

Santa Ana, California, ended 2025 below its 2015 population high: 315,586 residents, compared with 334,523 at the peak. Its city-limit count moved from 325,069 in 2010 to 315,586 in 2025. The largest annual change in the displayed series occurred in 2020: 19,674 fewer residents than the preceding estimate. That change coincides with the transition between Census vintages.

These figures measure Santa Ana 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.
