Jobs & Economy in San Diego
San Diego's economy is genuinely anchored by three real, distinct pillars: an enormous military presence (115,000-plus regional active-duty Navy and Marine Corps personnel), a world-class biotech/life-science cluster (the nation's 3rd-largest), and a genuine binational border economy with Tijuana -- alongside a real, disclosed RISING 2026 unemployment trend worth stating honestly.

More than 115,000 active-duty Navy and Marine Corps personnel are stationed regionally, between Naval Base San Diego (20,000 military, 6,000 civilians, the Pacific Fleet's principal homeport) and Marine Corps Base Camp Pendleton (roughly 49,000 military, ~80,000 daytime population) -- making San Diego the real, genuine operational nerve center of the U.S. Navy's Pacific Fleet.
Biotech: A Real, World-Class Industry Cluster
San Diego hosts over 1,400 life-science companies, 71,448-plus direct jobs, and $54.1 billion-plus in annual economic output -- the nation's 3rd-largest biotech cluster, behind only Boston and the San Francisco Bay Area, spanning genomics, cell/gene therapy, RNA therapeutics, and immunotherapy.
A Real, Disclosed Rising 2026 Unemployment Trend
San Diego County unemployment ran a real, disclosed RISING trend within 2026 itself -- 3.9% in May, climbing to 5.2% by July, above both the prior year's 4.8% and California's broader 4.7% comparison figure -- worth stating honestly rather than only citing the more favorable spring figure. Government-sector employment fell more than 17,000 jobs year-over-year, and professional/business services lost nearly 7,000.
A Real, Genuine Binational Border Economy With Tijuana
As detailed in full on the base record, San Diego shares a real, economically significant $230 billion combined regional economy with Tijuana, Mexico, anchored by the San Ysidro Port of Entry (the busiest land border crossing in the Western Hemisphere) -- a genuine, distinctive economic feature found in few other US metros.
