San Diego's population grew due to increased immigration

San Diego's population grew by 0.4% in 2024, reaching 3,298,799, mainly due to a 22% increase in immigration. This growth offset a net loss of nearly 24,000 residents who left the county during the same period. The rise in immigrants, totaling 24,226, was the highest in 15 years. Many migrants arrived from Latin America, Africa, Europe, and Asia, with a significant number seeking asylum. The Census Bureau improved its counting methods to better reflect real-time immigration trends. Despite the population gain, San Diego continues to face challenges as many locals leave for more affordable housing. The ongoing outflow of native-born residents highlights the need for solutions to housing issues in the region.
