The economy grew faster in the third quarter than initially thought, expanding at a solid 3.9% annual rate, the Commerce Department said Tuesday.
The figure was unexpectedly better than the 3.5% annual rate the government reported in its first estimate last month.
Economists had forecast the growth rate would be revised down to 3.3%.
The Commerce Department produces three estimates of total economic output, also known as gross domestic product, for each quarter.
Third-quarter growth still was down from the 4.6% pace in the second quarter, but the decline was expected as much of the spring activity came from pent-up demand after the economy sharply contracted during a winter marked by severe weather.
Stronger consumer spending was a key factor in the upward revision of third-quarter growth, the Commerce Department said.
Spending increased 2.2% in the third quarter, better than the 1.8% increase in the first growth estimate.
Still, consumer spending growth slowed in the third quarter after increasing 2.5% in the second quarter.
Other factors in the third-quarter revision were a smaller than initially estimated drop in private business inventories and a larger increase in nonresidential investment, the Commerce Department said.
Federal government spending also played an important role in third-quarter growth, increasing 9.9%. Those expenditures decreased by 0.9% in the second quarter.
