Unemployment rates rose in more than two-thirds of the nation's largest metro areas in November, a sharp reversal from the previous month and the most since June.
The Labor Department said Tuesday that unemployment rates rose in 258 of the 372 largest cities, fell in 88 and remained the same in 26. That's worse than the previous month, when rates fell in 200 areas and rose in 108.
The economy is strengthening, but employers have been reluctant to create jobs. Hiring will pick up in 2011, but not enough to significantly lower the unemployment rate, economists forecast.
Metro areas in states with the weakest housing markets, such as California, Nevada, Florida and Georgia, are also seeing increases in unemployment. Las Vegas, Atlanta, San Francisco and Miami all saw their rates rise. Construction jobs haven't returned. Real estate agents and mortgage broker positions have also disappeared.
"The areas really affected by the housing bust have yet to come back," said Jim Diffley, a regional economist at IHS Global Insight.
And in some other hard-hit areas, many laid-off workers are giving up searches. Fourteen metro areas in Michigan reported lower unemployment rates. That included Detroit, where the rate fell to 12 percent from 13.3 percent. But thirteen of them also said that fewer people are employed or looking for work. Once the unemployed stop hunting for jobs, the government no longer counts them as unemployed.
Detroit's work force dropped by 36,500 in November, or 1.7 percent. Anne Arbor, Battle Creek, Flint and Lansing all saw smaller drops.
"That is not a good sign," said Sophia Koropeckyj, managing director for Moody's Analytics. "It means that people are giving up and could be leaving the state."
