California’s population grew by just 19,200 people in the year ending July 1, 2025, reaching about 39.53 million residents. While statewide growth was slow, some regions, like Sacramento and the Central Valley, continue to gain residents steadily, whereas San Francisco’s recent rebound has largely stalled. This uneven growth is affecting housing, schools, and planning priorities across the state.
Statewide Snapshot
The California Department of Finance reported that the state’s population grew by about 19,200 people—a 0.05% increase—to roughly 39.53 million in the year ending July 1. International immigration accounted for most of the growth, though the end of several humanitarian programs limited the increase. Meanwhile, California saw a net domestic migration loss of around 216,000 people, offsetting much of the international inflow.
Sacramento Climbs, San Francisco Stalls
Population changes are uneven across the state. Sacramento County added nearly 8,800 residents, one of the largest gains among major counties. In contrast, San Francisco’s population grew by fewer than 300 people and remains roughly 30,000 below its pre-pandemic level.
Most of California’s population growth occurred in the Central Valley, where people are moving from—or bypassing—coastal cities. This trend is driving up demand in inland housing markets, while growth in some coastal areas remains slow.
