U.S. unemployment claims surged by 3.28 million last week, the highest number ever recorded in a single week and more than quadruple the previous record, according to Labor Department data released Thursday.

The data showed claims surged by over 3 million in a week alone — a stark contrast to a historic low of barely 200,000 unemployment claims just three weeks ago — as the economy struggles amid shutdowns due to the coronavirus pandemic. The previous record was 695,000 claims in October 1982.
