U.S. gross domestic product grew by an annualized 3.1 percent in the July-September quarter, according to a revision issued Thursday by the Commerce Department.
October's initial estimate was 2 per cent, followed by a first revision last month to 2.7 percent.
The Commerce Department's Bureau of Economic Analysis attributed the latest revision to more complete data on U.S. exports, which were higher than first estimated, as well as higher spending on health
care and state and local governments spending more on buildings.
The growth in third-quarter inflation-adjusted GDP was attributed to rising personal consumption and federal spending, higher inventory and housing investment and expanded exports, along with a fall in imports.
U.S. growth at an annualized rate was 2 percent in the first quarter and 1.3 percent in the second quarter.
The Conference Board, a private business think tank, was scheduled to release its closely watched index of leading U.S. economic indicators after 10 a.m. (1500 GMT).
