Overview

• California’s population reached over 39.5 million in 2024, marking a 1% increase and the second consecutive year of growth after pandemic-era declines.
• Natural population growth, with births outpacing deaths, accounted for a gain of 114,805 people, partially offset by a net domestic migration loss of about 7,000 residents.
• Immigration, bolstered by improved data tracking and an influx of international arrivals, played a key role in the state’s population rebound.
• Seven of the state’s ten largest cities, including Bakersfield (1.2% growth) and San Diego (1%), saw gains, while Bay Area cities like San Francisco and San Jose experienced slight declines.
• Housing development remained slow, growing by just 0.84% in 2024, with one in five new units being accessory dwelling units (ADUs).
