According to the BEA (Bureau of Economic Analysis) of the US Department of Commerce, real gross domestic product (GDP) increased 0.1% in the fourth quarter of 2012.
The BEA's advance estimate had GDP declining by 0.1% in the fourth quarter, but their second estimate (which is based on more complete data) is showing a very small increase of 0.1%. This means that the United States will likely continue its streak of positive quarterly GDP growth, albeit just barely.
The last time that the United States posted a quarterly decline in GDP growth was the second quarter of 2009 (-0.3%).
