Economy of San Diego

business has been in steady decline since peaking in 2008, when the Port hosted over 250 ship calls and more than 900,000 passengers. By 2011 the number of ship calls had fallen to 103 (estimated). Holland America and Carnival Cruises operated weekly cruises to the Mexican Riviera for many years, but both ended their regular scheduled service in spring 2012, which was an economic loss to the region of more than $100 million. The decline is blamed on the slumping economy as well as fear of travel to Mexico due to well-publicized violence there.

There are local cruises in San Diego Bay and Mission Bay, available through companies such as Hornblower and H&M. These include sightseeing and "sunset" cruises as well as private-event or "party" cruises. Also available are whale watching cruises to observe the migration of tens of thousands of gray whales that pass by San Diego, peaking in mid-January, and year-round sport fishing expeditions.

International trade

San Diego's commercial port and its location on the United States-Mexico border make international trade an important factor in the city's economy. The city is authorized by the United States government to operate as a Foreign Trade Zone.

The city shares a 15-mile (24 km) border with Mexico that includes two border crossings. San Diego hosts the busiest international border crossing in the world, in the San Ysidro neighborhood at the San Ysidro Port of Entry. A second, primarily commercial border crossing operates in the Otay Mesa area; it is the largest commercial crossing on the California-Baja California border and handles the third highest volume of trucks and dollar value of trade among all United States-Mexico land
