WASHINGTON (AP) The U.S. economy shrank at a dizzying 33% annual rate in the April-June quarter by far the worst quarterly plunge ever when the viral outbreak shut down businesses, throwing tens of millions out of work and sending unemployment surging to 14.7%, the government said Thursday.

The Commerce Departments estimate of the second-quarter decline in the gross domestic product, the total output of goods and services, marked the sharpest such drop on records dating to 1947. The previous worst quarterly contraction, a 10% drop, occurred in 1958 during the Eisenhower administration.

Last quarters drop followed a 5% fall in the January-March quarter, during which the economy officially entered a recession triggered by the virus, ending an 11-year economic expansion, the longest on record in the United States.
