The Bay Area’s dynamic economy and well-developed transportation system give workers access to jobs located in numerous places within the region’s 7,000-square-mile territory. And while many workers are lured across county borders, a much larger proportion work closer to home. Overall, 65 percent of Bay Area workers hold jobs in the same county they live in. Jobs-rich communities in Santa Clara County top the charts for this metric with 88 percent of residents working in-county. Conversely, four in ten Contra Costa County residents commute to neighboring counties for work.
Of the counties that attract workers from outside their borders, San Francisco is far and away the leader, pulling in a net 150,000 commuters daily. Santa Clara County is number two in this category, with a net inflow of nearly 100,000 workers each day. These counties attract significant numbers of workers from suburban areas with significant amounts of housing but few higher-wage jobs. In addition to these intraregional commute patterns, the Bay Area experiences a net inflow of nearly 120,000 people who commute into the region each day for work.
