A tepid quarter for GDP

The first quarter of the year saw disappointing growth in the US economy. Here are the factors that caused GDP to grow just 1.8 percent.

This chart shows contributions to GDP growth during the first quarter from different sectors of the economy. Consumer spending was the highest contributor to growth, but other areas, like government and imports, subtracted from growth.

Thursday morning brought the first official look at GDP growth in the first quarter. Headline growth was a disappointing, if not surprising, 1.8%.

Here’s my usual graph of how various components of the economy contributed to overall growth.

Consumers continued to spend at a moderate pace; their spending grew at a 2.7% rate, thus adding 1.9 percentage points to overall growth. Equipment and software investment (up at a 12.6% rate), inventories, and exports also contributed to growth.

Residential investment fell back into negative territory, reflecting the latest down leg in the housing market. But the real negatives were structures (down at a 21.7% rate, thus cutting 0.6 percentage points from growth) and government (down at a 5.2% rate). Defense spending fell sharply (11.7% rate), and state and local continued its decline (down at a 3.3% rate).

Note: As usual, imports subtracted from growth as conventionally measured. As discussed in this post and this post, I’d like to see GDP contributions data that allocate imports across the other sectors. Such data would reveal, for example, how much consumer spending contributed to growth in the U.S. economy itself. Presumably it’s less than the 1.9 percentage points shown in the chart, which reflects consumer spending that was satisfied by both domestic and international production, but we don’t know by how much.
