Real gross domestic product (GDP) increased at an annual rate of 3.5 percent in the third quarter of 2018 (table 1), according to the “advance” estimate released by the Bureau of Economic Analysis. In the second quarter, real GDP increased 4.2 percent.
The Bureau emphasized that the third-quarter advance estimate released today is based on source data that are incomplete or subject to further revision by the source agency (see “Source Data for the Advance Estimate” on page 2). The “second” estimate for the third quarter, based on more complete data, will be released on November 28, 2018.
The increase in real GDP in the third quarter reflected positive contributions from personal consumption expenditures (PCE), private inventory investment, state and local government spending, federal government spending, and nonresidential fixed investment that were partly offset by negative contributions from exports and residential fixed investment. Imports, which are a subtraction in the calculation of GDP, increased (table 2).
The deceleration in real GDP growth in the third quarter reflected a downturn in exports and a deceleration in nonresidential fixed investment. Imports increased in the third quarter after decreasing in the second. These movements were partly offset by an upturn in private inventory investment.
Current dollar GDP increased 4.9 percent, or $247.1 billion, in the third quarter to a level of $20.66 trillion. In the second quarter, current-dollar GDP increased 7.6 percent, or $370.9 billion (table 1 and table 3).
The price index for gross domestic purchases increased 1.7 percent in the third quarter, compared with an increase of 2.4 percent in the second quarter (table 4). The PCE price index increased 1.6 percent, compared with an increase of 2.0 percent. Excluding food and energy prices, the PCE price index increased 1.6 percent, compared with an increase of 2.1 percent.
Personal Income (table 8)
Current-dollar personal income increased $180.4 billion in the third quarter, compared with an increase of $180.7 billion in the second quarter. Accelerations in rental income, wages and salaries, and nonfarm proprietors’ income were offset by a downturn in farm proprietors’ income and a slowdown in dividend income.
Disposable personal income increased $155.0 billion, or 4.1 percent, in the third quarter, compared with an increase of $168.9 billion, or 4.5 percent, in the second quarter. Real disposable personal income increased 2.5 percent, the same increase as in the second quarter.
Personal saving was $999.6 billion in the third quarter, compared with $1,054.3 billion in the second quarter. The personal saving rate — personal saving as a percentage of disposable personal income — was 6.4 percent in the third quarter, compared with 6.8 percent in the second quarter.
