After weeks of ominous news, March 26 was the day the coronavirus outbreak cemented itself as an economic catastrophe in the U.S. On that day, the Department of Labor released its weekly estimate of initial unemployment insurance claims, one official measure the government uses to determine how many people are out of work across the country. 

The previous week, 282,000 people had filed for unemployment insurance. In the history of the data series, going back to 1967, no single week had reached the mark of 700,000 people filing for unemployment. On March 26, 3.3 million people reported having lost their jobs in the seven days prior.
