America's Leading Venture Capital Area Codes

Venture capital is the fuel that drives America's high-tech innovation machine. In previous posts I've examined venture capital investment and start-ups at the metro level, tracking overall levels of activity and investment, per capita trends and the factors that are associated with venture capital and start-up activity. Today, I turn to a finer-grained level of geographic detail, exploring venture capital and start-up activity across telephone area codes.

The first map (above) charts the number of venture capital deals by area code. Not surprisingly, the largest concentrations are on the West and East coasts, in Silicon Valley and the San Francisco Bay Area, Los Angeles and Southern California and Seattle, and the Boston-New York-Washington corridor back East, with smaller concentrations in Austin, Denver, North Carolina's Research Triangle, Pittsburgh and several other areas.
