Overall in 2015, the US economy is estimated to have grown at a rate of 2.4 per cent.
Explaining the better-than-expected figures, the Commerce Department noted that consumer spending was greater than expected.
Reacting to the figures, Gus Faucher, an economist at PNC Financial Services Group told Bloomberg: "It’s really US consumers who are powering the global economy forward at this point."
The 1.4 per cent figure marks a slowdown on the 2.2 per cent average pace of growth set in the first three quarters of 2015.
