Real gross domestic product (GDP) is comprised of four major subcomponents: personal consumption expenditures, gross private domestic investment, net exports, and government consumption expenditures. In the latest Q2 2024 second estimate update it was reported that real GDP increased at an annual rate of 3.0%. Three of the four components made positive contributions.
- Gross private domestic investment (GPDI) contributed 1.31
- Revised down from Q2 advanced estimate
- Up from Q1 final estimate
- Government consumption expenditures (GCE) contributed 0.46
- Revised down from Q2 advanced estimate
- Up from Q1 final estimate
- Personal consumption expenditures (PCE) contributed 1.95
- Revised up from Q2 advanced estimate
- Up from Q1 final estimate
- Net exports of goods and services (NEGS) contributed -0.77
- Revised down from Q2 advanced estimate
- Down from Q1 final estimate
Over time, the personal consumption expenditures (PCE) component has shown the most consistent correlation with real GDP. When PCE has been positive, GDP has usually been positive, and vice versa (although this was not the case in Q2 2022).
Visualizing GDP
The accompanying chart is a way to visualize real gross domestic product (GDP) change since 2007. The chart uses stacked columns to segment the four major components of GDP with a solid line overlay to show the sum of the four, which is real GDP itself. The data source for this chart is the Excel file accompanying the BEA's latest GDP news release (see the links in the right column). Specifically, it uses Table 2: Contributions to Percent Change in Real Gross Domestic Product.
Here is the same chart but only showing the latest two years to get a clearer picture of each components' most recent contributions.
Components as a Percent of Real GDP
Here is the latest break down of the components as a percent of real GDP:
We stated earlier that the personal consumption expenditures (PCE) component has shown the most consistent correlation with real GDP. When PCE has been positive, GDP has usually been positive, and vice versa. As for the role of PCE in GDP and how it has increased over time, here is a snapshot of the PCE-to-GDP ratio since the inception of quarterly GDP data in 1947. To two decimal places, the latest ratio of 68.73% is just below its peak of 69.42% reached in Q2 2022.
GDP Components and Recessions
Let's close with a look at the inverse behavior of the four GDP components during recessions. PCE and GPDI generally increase as a percent of GDP, whereas GCE and NEGS decline. Note the different vertical axes (PCE on the left, GDPI, GCE, and NEGS on the right) to highlight the frequent inverse correlations.
