Strike up the band. Break out the confetti. The market’s going to love this. The U.S. unemployment rate dropped to 8.3 percent and non-farm jobs grew by 243,000 in January.

This morning’s monthly report from the U.S. Department of Labor blasted through even the most optimistic of expectations. The jobs gain would have been the largest since May 2010, except that the Labor Department’s data group adjusted 2011′s jobs numbers. Now, only March (+246,000) and April (+251,000) had stronger numbers.

January is the second consecutive month to beat estimates. Economists predicted anywhere from MarketWatch’s tepid 121,000 to the more optimistic 182,000 in the Bloomberg survey. None of the widely reported surveys saw a decline in the unemployment rate.

Indeed, the unemployment rate, which has been declining very slowly since hitting a peak of 10.1 percent in late 2009, is now at the lowest point since February 2009. The government report also put the number of unemployed at 12.8 million. A year ago it was at 13.9 million.

While governments continued to cut jobs — federal jobs were cut by 6,000 and local government cut 11,000 positions — the private sector added 257,000. This was more than 50 percent higher than the ADP estimate earlier in the week.

Surprising economists and putting an upbeat end to 2011, the U.S. unemployment rate declined to 8.5 percent in December while the economy added 200,000 new non-farm jobs.

It was the fourth consecutive month of declines in the unemployment rate, and the sixth month of six-figure job growth. December’s unemployment rate is the lowest since early 2009.

The official numbers from the U.S. Department of Labor beat all but the most aggressive estimates. Economists were expecting the unemployment rate to rise, and predicted new job numbers in the 150,000 range.

The unemployment rate nudged down, but new jobs in October fell short of what economists expected, according to numbers released this morning by the U.S. Department of Labor.

Economists were expecting at least 100,000 new jobs to have been created last month. Instead, the numbers show only 80,000 new non-farm jobs, all of them coming from the private sector. Government at every level cut a total of 24,000 positions, continuing a trend that began mid-2008 at the state and local levels.

The New York Times described the increase as “mediocre,” and said the report offers little guidance about the direction of the U.S. employment outlook.

Despite the minor drop in the unemployment rate — from the 9.1 percent where it’s been since July, to 9.0 percent — the Labor Department’s Bureau of Labor Statistics said the total number of unemployed barely changed. In October, there were 13.9 million Americans out of work. In October, the number was almost 14 million.
