US employment grew solidly last month and the jobless rate dropped to a near three-year low of 8.5 percent, offering the strongest evidence yet of an acceleration in economic activity.
Nonfarm payrolls increased 200,000 last month, the Labor Department said on Friday, the most in three months and way above economists' expectations for a 150,000 gain.
The economy needs to sustain the current pace of job creation to signal a robust recovery is finally under way.
The unemployment rate dropped from a revised 8.7 per cent in November, which was previously reported as 8.6 per cent. The jobless rate is now the lowest since February 2009.
However, the payrolls count for October and November was revised to show 8,000 fewer jobs created than previously reported, taking some edge off the report.
The separate household survey, from which the jobless rate is derived, showed gains in employment and a modest decline in the labour force, helping to lower the jobless rate.
But the economy needs even faster pace of job growth over a sustained period to make a noticeable dent in the pool of the more than 20m Americans who remain either out of work or underemployed since the end of the 2007-09 recession.
With the labour market still far from healthy, the debt crisis in Europe unresolved and tensions over Iran threatening to drive up oil prices, the U.S. economy faces stiff headwinds.
Economists predict the recovery will lose a step early this year after expanding in the fourth quarter at what is expected to be the fastest pace in 1-1/2 years.
This should keep alive the possibility of the Federal Reserve embarking on a third round of asset purchases, or quantitative easing, to spur stronger growth.
