A Labor Department report released Friday showed the West absorbing the worst of the recession, which is now the longest since World War II. California, Nevada and Oregon endured particularly heavy job losses in construction, manufacturing and tourism.
The region has been pounded because it was the epicenter of the housing boom that collapsed. As home values plummeted, the West lost jobs and wealth, and consumers grew skittish about spending.
"The West is where houses are being abandoned most quickly because it has the largest percentage of the population under water -- owing more on their houses than they're worth," said Robert Reich, labor secretary under President Bill Clinton and now a professor at the University of California, Berkeley. "They lose their capacity to borrow. All of that means that they can't buy very much."
The West reported the highest regional jobless rate for May: 10.1 percent. The last time any region had an unemployment rate of at least 10 percent was in September 1983, when the economy was emerging from a severe recession.

"It's difficult to keep major projects going -- like casinos -- in Las Vegas. That's pretty much come to a halt," said Steve Cochrane, managing director at Moody's Economy.com.
In California, the jobless rate jumped to 11.5 percent last month. In Nevada, it rose to 11.3 percent, and in Oregon, to 12.4 percent. All three figures were records, based on documentation going back to 1976.
After the West, the Midwest had the second-highest unemployment rate, at 9.8 percent. The South's jobless rate was 8.9 percent. The Northeast had the lowest, 8.3 percent.
The government report showed employment conditions deteriorating in 48 states and the District of Columbia last month.
Michigan, the heart of the sinking auto industry, had the highest unemployment rate: 14.1 percent.
Eight states had record-high jobless rates. Only two -- Nebraska and Vermont -- reported no increases. Nebraska's jobless rate dipped, and Vermont's was flat.
The five other states that set new unemployment highs were North Carolina, Oregon, Rhode Island, South Carolina, Florida and Georgia.
After Arizona and Florida, the next-largest percentage drop in jobs last month was Oklahoma, followed by Arkansas, Kentucky and Michigan.
Nationwide, the jobless rate stands at a quarter-century high of 9.4 percent. Analysts say companies are unlikely to ramp up hiring until they feel sure their sales are rebounding and that any economic recovery will have staying power.
Some economists say the nation's jobless rate could rise as high as 11 percent by the summer of next year before it starts a slow descent. The highest rate since World War II was 10.8 percent at the end of 1982.
North Dakota and Nebraska reported the lowest unemployment rates: 4.4 percent each. North Dakota has been helped by the oil business. Nebraska has been supported by farm businesses.
Neither state ever got carried away by the housing boom, either, so they never suffered huge hits to household wealth. Nebraska also has benefited from the relative strength of two of its main industries: agriculture and food-production.
