- The unemployment rate fell to 13.3% in May, according to a Bureau of Labor Statistics report on Friday.
- The agency admitted the real unemployment rate likely exceeds 16%.
- That's due an error in how furloughed workers were treated in the data sample. April's unemployment rate would have been nearly 20% absent that same error.
The unemployment rate in the U.S. improved last month as millions of people returned to the workforce.
But the official 13.3% unemployment rate, while still high relative to any point since the Great Depression in the early 20th century, likely understates the economic damage wrought by the coronavirus pandemic.
The real unemployment rate is likely at least 16%, according to the federal government.
That would mean roughly 1 in 6 people can't find work.
The Bureau of Labor Statistics, which published its monthly jobs report Friday morning, admitted the official unemployment rate may be low relative to reality due to an error in data collection.
Around 21 million Americans were unemployed as of mid-May, a reduction of 2.1 million people from a month earlier, according to BLS data.
That number includes workers who were furloughed — meaning those who were temporarily laid off — by their companies in recent weeks.
More than 15 million workers — about 73% — of the total unemployed are on temporary layoff and expect to be recalled to work once business rebounds.

That share is far higher than at any other time in modern history (with the exception of April, when the share was 78.3%).
Yet the BLS may have severely undercounted the number of workers classified as "unemployed on temporary layoff" due to an error, the agency said.
The BLS determines how many people are unemployed based on a household survey. Survey interviewers misclassified several furloughed workers as being "absent from work due to 'other reasons,'" according to the BLS.
That's the same category of workers who'd be on vacation, for example.
The overall unemployment rate would have been "about 3 percentage points higher than reported" if those individuals had been identified correctly, according to the agency. (The estimate isn't seasonally adjusted.)
That would put the official unemployment rate at 16.3%.
The true rate could be higher still.
The unemployment rate doesn't include the share of workers who may have dropped out of the workforce, perhaps due to feeling pessimistic about the chances of finding a job in the current economy. More than 6 million workers have dropped out of the labor force since February.
In fact, the unemployment rate is a much-higher 21.2% as judged by another metric.
This metric, which the BLS calls U-6, includes people "marginally attached to the labor force." These are people who aren't currently working or looking for work but are available for work, as well as part-time employees who want and are available for full-time work but have had to settle for part-time employment.
The U-6 metric doesn't include the workers misclassified by the agency.
Of course, furloughed workers could be recalled back to work quickly, depending on the speed of the economic rebound as states begin to reopen certain business sectors. The unemployment rate would likely rebound faster in this eventuality than if the layoffs were permanent.
The same misclassification phenomenon occurred in April, too — the official 14.7% unemployment rate would have been nearly 20% if furloughed workers had been identified correctly, the BLS said.
"BLS and the Census Bureau are investigating why this misclassification error continues to occur and are taking additional steps to address the issue," the agency said Friday in the jobs report.
"According to usual practice, the data from the household survey are accepted as recorded," the agency said. "To maintain data integrity, no ad hoc actions are taken to reclassify survey responses."
