U.S. gross domestic product rose a revised 0.1 percent in the fourth quarter -- an improvement from the intially-estimated 0.4 percent contraction, the U.S. Commerce Department announced Thursday.

However, although the growth rate was an improvement, it still marked the slowest pace of growth since the first quarter of 2011. The economy must grow at a much faster rate to lower the nation's high unemployment rate.
