From the BEA: Gross Domestic Product, Fourth Quarter and Year 2023 (Third Estimate), GDP by Industry, and Corporate Profits
Real gross domestic product (GDP) increased at an annual rate of 3.4 percent in the fourth quarter of 2023, according to the “third” estimate released by the Bureau of Economic Analysis. In the third quarter, real GDP increased 4.9 percent.
The GDP estimate released today is based on more complete source data than were available for the “second” estimate issued last month. In the second estimate, the increase in real GDP was 3.2 percent. The update primarily reflected upward revisions to consumer spending and nonresidential fixed investment that were partly offset by a downward revision to private inventory investment.
