San Jose has the greatest share of advanced industry employment in the country. Advanced industry includes tech, engineering, and energy jobs that drive innovation. In fact, it took first by a mile. 30% of employment in the San Jose metro is in the advanced industry sector. Seattle came in second at 16% and San Francisco was in 5th with 14%.
Why is this important? Not only are these the jobs that drive economic growth in the country, but the pay is spectacular. In 2013, workers in this sector nationwide raked in an average of $90k a year. However in Silicon Valley, that number is doubled to an astounding $180k per year.
