California's industries are widely dispersed across the state. While there are traditionally heavy
concentrations of high-tech companies in the Bay Area, Los Angeles, and San Diego, companies may be
found across the state. This section contains maps intended to give an indication of relative concentrations
of industries in the four sectors (nanotech, biotech, advanced manufacturing, and intelligent transportation)
discussed in this toolkit. It is not intended as a comprehensive atlas of these industries; further resources
are provided where appropriate for more detailed information. Please note that the maps in this section
have been compiled by different organizations, and consequently vary in scope and degree of detail.
