Economists expect only modest improvement in the second half of the year. Most believe the economy will keep growing, but at a subpar rate of around 2 percent.
"The economy was sluggish in the second quarter and the slight upward revision ... does nothing to change that picture," said John Ryding, an economist at RDQ Economics, in a note to clients.
The report was the government's second look at gross domestic product for the second quarter. GDP measures the country's total output of goods and services, from the purchase of restaurant meals to construction of highways and bridges. A third and final estimate of second-quarter growth will be released next month.
Growth at or below 2 percent is not enough to lower the unemployment rate, which was 8.3 percent in July. Most expect the unemployment rate to stay above 8 percent for the rest of this year.
