From the BEA: Gross Domestic Product: Fourth Quarter and Annual 2017 (Second Estimate)

Real gross domestic product (GDP) increased at an annual rate of 2.5 percent in the fourth quarter of 2017, according to the "second" estimate released by the Bureau of Economic Analysis. In the third quarter, real GDP increased 3.2 percent.

The GDP estimate released today is based on more complete source data than were available for the "advance" estimate issued last month. In the advance estimate, the increase in real GDP was 2.6 percent. With this second estimate for the fourth quarter, the general picture of economic growth remains the same.

Here is a Comparison of Second and Advance Estimates. PCE growth was unrevised at 3.8%. Residential investment was revised up from 11.6% to 13.0%. Most revisions were small. This was at the consensus forecast.
