The world's largest economy US grew at a slower pace than projected, expanding just 2.8% in the last three months of 2010.
The downward revision from the earlier estimate of 3.2% was mainly on account of lesser consumer spending.
"Real gross domestic product -- the output of goods and services produced by labour and property located in the US -- increased at an annual rate of 2.8% in the fourth quarter of 2010," US Bureau of Economic Analysis said today.
The American economy, which fought the financial meltdown with heavy doses of stimulus, had expanded 2.6% in the 2010 September quarter.
Consumer spending rose 4.1% in the last three months of 2010 as against earlier projection of 4.4%.
Going by official data, the fourth-quarter growth of 2.8% reflected positive contributions from personal consumption expenditures (PCE), exports, and non-residential fixed investment.
But these gains were partly offset by negative contributions from private inventory investment and state and local government spending, BEA said in a statement.
The market value of the national economy stood at $14.86 trillion in December-end, 2010.
Global economy is seeing a fragile recovery, led by emerging nations, while many advanced economies are still grappling with sluggish growth.
Meanwhile, latest figures released today showed that UK economy contracted more than expected at 0.6% in the last three months of 2010.
During the same period, eurozone -- a grouping of 16 nations that share the common currency euro -- registered a growth of 0.3%.
