A ‘misclassification error’ made the May unemployment rate look better than it is. Here’s what happened.

When the U.S. government’s official jobs report for May came out on Friday, it included a note at the bottom saying there had been a major “error” indicating that the unemployment rate likely should be higher than the widely reported 13.3 percent rate.

The special note said that if this “misclassification error” had not occurred, the “overall unemployment rate would have been about 3 percentage points higher than reported,” meaning the unemployment rate would be about 16.3 percent for May. But that would still be an improvement from an unemployment rate of about 19.7 percent for April, applying the same standards.
