🔑 The key industries

There are seven key industries — all with 100,000+ employees — that represent ~67.5% of the San Diego metro area’s economy, based on data from the US Census Bureau. We’ve listed them in order of employment numbers.

Health care + social assistance | 13.6% or 208,979 employees
As a county with millions of people, locals look to our healthcare system for support. Many services are provided outside clinical settings to improve community wellbeing and help residents lead healthy lives.

Professional, scientific + technical services | 12% or 183,757 employees
This sector encompasses many of the jobs that help San Diego get recognized for advancing our body of knowledge and improving productivity. Many companies fall into this category — from the engineers at Sempra Energy to the developers at Qualcomm.

Retail trade | 10.3% or 158,582 employees
Ka-ching — every time you make a purchase you’re helping the local retail industry. Any position required to put products on shelves falls into this category, from the person bagging groceries to the individual monitoring inventory across a chain of stores.

Manufacturing | 9.7% or 149,802 employees
We already talked about buying items, but what about making them? The people responsible for assembling goods fall into this category, like the people who make glucose monitors at DexCom, Inc. or the employees making electronics at Sony.

Education | 8.6% or 131,690 employees
San Diego County has 42 school districts — that’s a lot of teachers + staff. Beyond that, we have many universities, with UC San Diego and San Diego State University being the largest.

Construction | 6.8% or 105,112 employees
San Diego wasn’t built in a day. In fact, there’s always construction, and companies in this industry work to improve our buildings and keep this city America’s Finest.

Accommodation + food services | 6.5% or 100,374 employees
Tourism and hospitality play important roles in our economy and help many locals earn a living. Some of our most luxurious — and delicious — attractions fall into this category, including visits to the Hotel del Coronado and our craft beer scene.

Note: The US Census Bureau collects data for civilian employees. There are approximately 110,000 active-duty service members in San Diego County, and over 35,000 civilian jobs in defense-related fields.
