The Port of Oakland loads and discharges more than 99 percent of the containerized goods moving through Northern California, the nation's fourth largest metropolitan area. Oakland's cargo volume makes it the fourth busiest containerport in the United States, and ranks San Francisco Bay among the three principal Pacific Coast gateways for U.S. containerized cargoes, along with San Pedro Bay in southern California and Puget Sound in the Pacific Northwest. About 58.9 percent of Oakland's trade is with Asia. Europe accounts for 10.3 percent, Australia/New Zealand and South Pacific Islands about 4.7 percent and other foreign economies about 8.8 percent. About 17.3 percent of Oakland's trade is domestic (Hawaii and Guam) and military cargo. California's three major containerports carry approximately 50 percent on the nation's total container cargo volume.
