The U.S. economy grew much faster than expected over three months ending in June, accelerating from the previous quarter and defying concerns about a possible slowdown.

U.S. GDP grew at a 2.8% annualized rate over three months ending in September. That figure doubled the annualized rate of growth undertaken over the previous quarter.

The economic expansion reflected a surge in consumer spending, the U.S. Bureau of Economic Analysis said on Thursday. The uptick in spending included purchases of housing, and cars, among other items, the BEA added.
