California remains America’s largest state, but aging residents, domestic migration, housing costs, and changing immigration patterns are reshaping its future.
Since 2000, California has experienced a long period of net domestic outmigration, meaning more people have moved from California to other U.S. states than have moved into California from elsewhere in the country.
According to U.S. Census Bureau estimates, California has lost several million residents through domestic migration since the early 2000s. Popular destinations for former Californians include states such as Texas, Arizona, Nevada, Florida, and North Carolina.
The reasons behind these moves are complex:
High housing costs
The search for larger homes and lower taxes
Remote work flexibility after the COVID-19 pandemic
Retirement decisions
Job opportunities in faster-growing regions
However, domestic migration losses do not mean California’s population has simply disappeared.
The state’s population has also been shaped by:
Natural increase (births exceeding deaths)
International immigration
Changes in household size and demographics
California remains the most populous U.S. state, with roughly 39 million residents.
California’s Population Is Getting Older
One of the biggest demographic changes is aging.
The number of Californians age 65 and older has increased rapidly. The Stanford Center on Longevity has highlighted that California’s older population is growing faster than many previous generations experienced.
California had approximately:
4.3 million residents age 65+ in 2010
More than 6 million residents age 65+ today
Projections showing continued growth toward 8 million or more older adults in coming decades
By 2060, demographic projections show California’s median age rising significantly compared with the state’s much younger population in the late 20th century.
In 1970, California’s median age was about 28 years old. Today it is in the mid-to-late 30s, and projections indicate continued aging.
This shift affects nearly every part of society:
Healthcare demand
Retirement services
Workforce availability
Housing needs
Public spending priorities
Immigration Has Slowed, But It Has Not Stopped
California’s immigrant population has played a major role in the state’s economy for decades.
Immigrants have contributed to:
Agriculture
Healthcare
Construction
Small business ownership
Technology and science
Manufacturing
However, international migration has changed. Immigration slowed during the pandemic years and has fluctuated because of economic conditions and federal policies.
Some areas, including parts of Los Angeles County, experienced declines or slower growth in foreign-born populations during the 2010s. But California remains home to one of the largest immigrant populations in the United States.
Nearly 11 million immigrants live in California, representing roughly one-quarter of the state’s population.
California’s Poverty Problem Is Closely Linked to Housing Costs
California frequently ranks among the states with the highest poverty rates when measured using the Supplemental Poverty Measure (SPM), which considers housing costs, taxes, and government benefits.
The reason is not simply immigration.
Researchers point to several major factors:
Extremely expensive housing markets
High rental costs
Income inequality
Limited housing supply in many communities
Regional differences in wages and expenses
A family earning an income considered middle class in another state may struggle financially in areas such as Los Angeles, San Francisco, or San Diego because housing consumes such a large portion of household income.
California’s Economy Has Changed — Not Disappeared
It is true that California has fewer traditional manufacturing jobs than it did during the industrial era.
Factories that once dominated regions of Southern California and other parts of the state declined because of automation, globalization, and economic restructuring.
But California continues to be a major center for:
Technology
Biotechnology
Aerospace
Clean energy
Entertainment
Agriculture
Advanced manufacturing
The state’s economic challenge is not a lack of innovation. It is whether California can make itself affordable enough for workers, families, and businesses to remain competitive.
The Future of California: An Older State Searching for Balance
California’s future will likely be shaped by a simple question:
Can a state built on growth adapt to an era of aging?
The challenge is balancing the needs of multiple generations:
Older residents who need healthcare and retirement support
Younger workers seeking affordable housing
Families trying to build long-term stability
Businesses looking for talent and competitive costs
California is not becoming empty. It is becoming older, more expensive, and more economically specialized.
The next chapter of the Golden State will depend less on how many people arrive — and more on whether the state can create conditions that allow people of all ages to stay.
