The US economy grew at an annualised rate of 3.1% in the third quarter, according to a third and final estimate released on Thursday by the US Department of Commerce.
This was higher than a 2.8% estimate published earlier by the Department.
The Department justified this final estimate by "an upward revision in exports and consumer spending," while private investment was partially revised downwards.
The new figure is higher than predictions by analysts, who had expected the estimate to remain unchanged at 2.8%, according to a consensus published by briefing.com.
The Commerce Department also confirmed an annualised growth of 3% for the second quarter of the year.
The annualised rate, the measure favoured by the United States, compares gross domestic product (GDP) with that of the previous quarter and then projects growth over the whole year at this rate.
The slight acceleration in the US economy between the second and third quarters was due to an increase in exports, household spending and government spending, according to the Commerce Department.
The first estimate of US GDP growth for the final quarter and for 2024 as a whole will be published on 30 January.
