Economic growth in the second quarter was slower than initially thought, according to a report from the Bureau of Economic Analysis Friday.

The Bureau reported that gross domestic product was 1.1 percent at an annual rate, less than the 1.2 percent they had initially estimated with less data. Private-sector economists had expected a downward revision.

Growth is, for now, still stronger than in the first quarter, when it came in at a meager 0.8 percent rate, and in the last quarter of 2015, when it was 0.9 percent. Nevertheless, Friday's report is one more indication that U.S. growth remains weak and disappointing.

The poor growth was attributable to one of the long-running problems plaguing the economy, namely slow business investment. Business fixed investment declined at a 2.5 percent annual rate.

Consumer spending, meaning, remained robust, marking the best quarter since late 2014. But slow government spending and low net exports kept the overall rate of growth down.

Americans' willingness to spend has kept up domestic demand, a hopeful sign that the economy can weather headwinds from abroad or other obstacles to greater growth. But the growth, for now, may be even weaker than the headlines suggest.

Gross domestic income, a measure of growth that measures income rather than spending, ran significantly lower in the second quarter. Averaging out GDP and GDI, a measure favored by some economists, puts growth just above zero at 0.2 percent for the second quarter, and suggests that commerce has slowed in each of the past four quarters.
