San Francisco Bay Area & Northern California County-to-County Worker Flows

Decennial Census Journey-to-Work Data


Background & Data Availability

Data on county-to-county worker flows based on Census 2000 was released by the U.S. Bureau of the Census on March 6, 2003. This data release only includes information on the total number of workers, not on the number of workers by means of transportation to work. Detailed information on county-to-county and place-to-place workers by means of transportation is available from Part 3 of the CTPP (Census Transportation Planning Package). This CTPP Part 3 data was released May 2004.

MTC analysts have prepared data tables summarizing the new Census 2000 county-to-county worker flows, with comparisons to previous census years. The geographic focus for the MTC analysis are the nine counties in the San Francisco Bay Area, and twelve Bay Area neighbor counties (Mendocino, Lake, Yolo, Colusa, Sacramento, Placer, San Joaquin, Stanislaus, Merced, San Benito, Monterey and Santa Cruz.)

These Bay Area and Northern California data are available in several formats, including PDF, HTML, and EXCEL spreadsheets.

The PDF version of these tables is available here: San Francisco Bay Area County-to-County Commuters

The EXCEL workbook of these tables is available here: Census2000_County2County.xls
