Location:
San Diego County encompasses a vast and geographically diverse 4,261 square miles in the extreme southwestern corner of the contiguous United States. It shares a 120-mile international border with Mexico (Tijuana) and is bordered by the Pacific Ocean to the west, Orange and Riverside counties to the north, and Imperial County to the east. The terrain ranges from over 70 miles of coastline and coastal plains to arid deserts in the Anza-Borrego region and forested mountains reaching over 6,000 feet. The City of San Diego, the county seat, is centrally located on the coast, featuring one of North America’s largest natural harbors, which supports a major port and U.S. Naval base.
Population:
With approximately 3.3 million residents, San Diego County is California’s second-most populous county and the fifth-largest in the U.S. The City of San Diego itself is the 8th-largest city in the nation, with a population of 1.38 million. The region is a major demographic crossroads, characterized by significant military, immigrant, and cross-border influences. The population is highly diverse: roughly 35% Hispanic/Latino, 41% White, 17% Asian, and 5% Black. This diversity is reflected in its vibrant neighborhoods, from the historic Barrio Logan to Little Italy. The county’s size leads to varied population densities, from the urban core of San Diego to sparse desert communities.
Economy:
The economy of the county and its central city is a powerful and diverse engine, historically anchored by the military and now driven by innovation. The combined Gross Regional Product (GRP) exceeds $240 billion.

This sector supports over 300,000 jobs and fuels related industries like shipbuilding and aerospace.
- Tourism & Hospitality: Leveraging its idyllic climate and beaches, the region is a world-class destination. Major attractions like the San Diego Zoo, Balboa Park, and Legoland draw millions of visitors annually, supporting a massive hospitality sector.
- Innovation & Life Sciences: Dubbed the “Cell Therapy Hub” and a global leader in biotechnology, the area is home to giants like Illumina and over 1,500 life science companies. This cluster is complemented by a strong technology and cybersecurity sector.
- International Trade: The Port of San Diego and the Otay Mesa border crossing facilitate immense volumes of cross-border trade and commerce with Mexico, making logistics a critical industry.
