SAN GABRIEL VALLEY — Slower Household Growth Could affect more than demand for apartments and homes. It could eventually influence local spending on furniture, groceries, banking, utilities and other services.
New analysis from Harvard University’s Joint Center for Housing Studies estimates recent immigration declines will significantly reduce household growth. The center projects about 420,000 fewer households per year from recent immigrants in 2026 and 2027 than under previous trends.
The estimate is national. It does not establish that El Monte, South El Monte, Baldwin Park, Rosemead or Irwindale will experience comparable declines.
Still, household formation matters because households represent important units of economic demand.
Slower Household Growth Could Affect Spending
The U.S. Census Bureau defines a household as everyone occupying a housing unit. That can include a person living alone, a family or unrelated people sharing a home.
Creating a household can generate spending beyond rent or mortgage payments.
Someone establishing a residence may buy furniture, appliances and household supplies. Residents may establish utility and internet accounts, purchase insurance and begin spending at nearby stores and restaurants.
Families can also create demand for child care, recreation and other services.
Harvard researchers estimate household growth from recent immigrants will fall to about 330,000 in 2026 and 143,000 in 2027. Their estimates assume net immigration of 300,000 people annually in 2026 and 2027.
The center previously reported that overall U.S. household growth slowed to 1.1 million households in 2025, down from 2 million in 2021.
Local Effects Require Local Data
Slower Household Growth Could have particular significance in communities where population growth supports local businesses.
A supermarket depends partly on the number of nearby households. The same applies to restaurants, banks, insurance agencies and personal-service businesses.
Housing would likely experience some of the most direct effects. Fewer households can reduce competition for available homes and apartments. That could ease some pressure on rents and prices.
Weaker demand can also influence whether developers believe new projects will generate sufficient returns.
The national projection alone cannot show whether those trends are occurring in the San Gabriel Valley. Local population, household and housing data would be needed to determine conditions in individual communities.
Readers can review the Joint Center for Housing Studies analysis and U.S. Census Bureau household definitions for additional information.
Demographic shifts often develop more gradually than changes in interest rates or employment. Their economic effects can still become significant over time.
For San Gabriel Valley businesses and policymakers, household growth provides another indicator worth tracking. If fewer households form locally, the effects could eventually reach housing demand, consumer spending and decisions by businesses considering future investment.
