There was a substantial population boom in Silicon Valley during 2012. Santa Clara County grew by an astounding 1.6% over the year, more than any other major county in all of California. The state average for population growth was half that at 0.8%. San Mateo, Alameda, and San Francisco also grew by over 1% but nothing matched Santa Clara County. This is great news. Since there is very little room for sprawl left in the Valley, as population grows our cities are becoming more dense. As density rises, the average cost of delivering services to residents should decrease while the market for world-class amenities increases. Congestion will also increase, but that will hopefully push government to improve public transit infrastructure throughout Santa Clara County.
