The US economy grew at an annual rate of 3.5% in Q3 2014, the Commerce Department has announced.
That was better than the 3% pace that economists had been expecting and follows the 4.6% growth rate recorded in Q2 2014.
Strong export growth and higher government spending helped to boost growth in Q3.
In a sign of confidence in the US recovery, on October 29 the Federal Reserve ended its stimulus scheme.
The fall in the unemployment rate to a six-year low has helped to boost that confidence.
“Today’s number represents a return to a healthy-looking trend. The most recent IMF forecasts suggest the US economy will grow 3.1% next year and 3.0% in 2016, and these could be revised further upwards in the coming months,” said Ben Brettell, senior economist at Hargreaves Lansdown stockbrokers.
The report was the first of three estimates of gross domestic product, so the figure could be revised up or down, over the coming months.
Growth was lifted in the third quarter by a sharp increase in government spending, which itself was boosted by a surge in defense expenditure.
Exports were another area of strength, they rose at an annual rate of 7.8%.
There will be a question over whether that pace can be maintained as important export markets for the US are struggling.
Growth in many European countries is stagnant and the Chinese economy is slowing down.
Consumption growth was relatively weak in the third quarter, running at an annual rate of 1.8%, but economists expect that to improve.
Overall it has been a volatile year for US growth data.
In Q1 2014 the economy contracted at an annual rate of 2.1% after severe weather hampered economic activity.
But Q2 2014 saw a rebound, growing at an annual pace of 4.6%.
Taken together the latest two quarters are the strongest consecutive quarters of growth since the second half of 2003.
On October 29 the Fed announced the end of its quantitative easing (QE) stimulus program.
QE started in November 2008 amid the financial crisis and fears that the US, and the rest of the world, might be facing another great depression.
Since then the Fed has bought $3.5 trillion of US government debt and bonds created out of home loans or mortgages.
It began to phase out the scheme last year and a fall in unemployment to 5.9% has encouraged the Fed to end it altogether.
However, interest rates will remain at a record low for a “considerable time” according to the US central bank.
