Silicon Valley has the nation's second-highest concentration of wealthy people, according to a U.S. Census Bureau report released Monday.
Sixteen percent of Santa Clara County households make at least $191,000 each year, putting them in the nation's top 5 percent of income-earners.
The only region to rank higher was the southwestern corner of Connecticut, an affluent bedroom community of New York City, where nearly 18 percent of households can count themselves in America's wealthiest 5 percent.
All of the greater Bay Area ranked high on the wealth concentration list based on five years of census surveys.
Coming in fourth, just after Washington, D.C., was the populous region encompassing the San Francisco Peninsula, East Bay and Marin County. Napa County ranked 10th nationwide, the Santa Cruz region 11th and Sonoma County 23rd.
The report mapping the concentration of high-income households came on the same day Texas Gov. Rick Perry was touring San Francisco and the Silicon Valley in a bid to attract high-tech businesses to his state.
Perry hopes to lure businesses because California voters in November passed Proposition 30, which raised income taxes on the wealthiest Californians -- people who make at least $250,000 -- by up to 3 percentage points for seven years. The education-funding measure, backed by Gov. Jerry Brown, also raised the sales tax by a quarter-cent for four years.

The wealthiest Texas region on the list, at No. 14, was oil-rich and sparsely populated Midland, the childhood home of former President George W. Bush. Next, at No. 24, was the Houston area.
