The 1 percent rate of decline in the April-June quarter followed decreases of 6.4 percent in the first quarter and 5.4 percent in the final three months of 2008, the sharpest back-to-back declines in a half-century. The four straight quarterly declines in GDP, which measures the country's total output of goods and services, mark the first time that has occurred on government records that date to 1947.
The recession that began in December 2007 is the longest since World War II, and the deepest in terms of the drop in the GDP, which is down 3.9 percent from its previous peak.
But economists are heartened that the decline slowed to 1 percent in the spring. Many analysts think that the government's $787 billion economic stimulus plan and the Cash for Clunkers program to boost car purchases will lift GDP growth to around 2 percent in the current July-September quarter.
However, the return to economic growth will not mean more jobs, at least at first. Economists believe the unemployment rate, currently at 9.4 percent, will keep rising through the spring of next year.
The Labor Department said Thursday that first-time unemployment claims fell to a seasonally-adjusted 570,000, from an upwardly revised 580,000 the previous week. The tally of those continuing to claim benefits dropped to 6.13 million from 6.25 million, the lowest level since early April.
The weekly figures remain far above the roughly 325,000 that analysts say is consistent with a healthy economy. New claims last fell below 300,000 in early 2007.
White House economic adviser Christina Romer said Tuesday the unemployment rate is likely to keep rising and hit 10 percent this year. That could discourage consumer spending and weaken any recovery.
The government makes three estimates of the economy's performance for any given quarter. Each new GDP estimate is based on more complete information.
Economists had expected that the second look at GDP for the spring would show the economy contracting at a 1.5 percent rate because they believed companies had cut back more sharply on their inventories.
While inventories were cut more than initially estimated, that weakness was offset by upward revisions in other areas.
The government found that consumer spending, which accounts for about 70 percent of total economic activity, fell at an annual rate of 1 percent in second quarter, a slight improvement from the 1.2 percent decline reported last month. Residential construction and exports also were revised to show smaller declines.
Federal Reserve Chairman Ben Bernanke said last week the economy appeared to be "leveling out," and was likely to begin growing again soon. President Barack Obama appointed Bernanke to another 4-year term Tuesday.
The Cash for Clunkers program, which provides consumers rebates of up to $4,500 for turning in old gas-guzzlers for fuel-efficient cars, has helped spur activity in the auto and related industries. The economy also has been helped by stabilization in the housing sector, as sales of new and existing homes have risen for four straight months.
