The gig economy may not be nearly as large as the all hype it receives would suggest — that’s according to a report the Bureau of Labor Statistics published on Friday which estimated that 1.6 million people, or about 1% of the U.S. workforce, use apps and sites to find work.

Of the 1.6 million people who use apps and sites to find work, the report found that 5.6% were full-time independent contractors, which are typically thought of as workers who use online platforms like Lyft, Uber and Airbnb. “You’d expect the share of independent contractors who use apps and sites to find work to be a lot higher,” said Ben Gitis, director of labor policy at the American Action Forum, an advocacy group.

“So, if online platforms work were reshaping the workforce, you’d see it prominently among independent contractors and you’d expect the number of independent contractors to grow, but, the data indicate the exact opposite,” he said. “And the portion of workers who are independent contractors has declined over the last decade, indicating that the gig economy is not substantially altering the workforce.”

The estimates from the BLS’s report align with a recent report on the gig economy published by the JPMorgan Chase Institute which showed that about 1.1% of U.S. families earned income from online platforms in the first quarter of 2018. However, the Federal Reserve found that 16% of adults earn money from online platforms. The reason for the discrepancy has a lot to do with the fact that there currently is no agreed upon definition of the gig economy, and for the Federal Reserve gig workers could be anyone from a babysitter to an Uber driver.

The BLS does not have an explicit definition for a gig worker, or a formal way of tracking them. It comes closest with its survey called the Contingent Worker Supplement, which studies “contingent workers” in temporary working arrangements that they don’t expect to last more than a year.

The new numbers regarding the share of workers who use online platforms to find work comes from the four new questions that were added to the supplement in May 2017 in attempt to gauge non-traditional working arrangements which may comprise the gig economy.

The BLS did not release the findings from the four questions when they released the May 2017 CWS report in June. “Essentially we found when we asked these four questions a lot of people said that they do all of their work online when in reality we know that a surgeon in a large hospital does not do all of their work online,” said Jim Borbely, an economist at the BLS.

“We think people misunderstood some of the questions and that led to a lot of confusion,” he added. Because of that, the BLS manually recoded the data in order to ensure that respondents’ answers correctly aligned with their working arrangements. Initially, Borbely said that the sample size consisted of 5 million respondents which was scaled down to 1.6 million people.

Some of the findings from the additional four questions include:

Of the 1.6 million electronically mediated workers, 0.6% did electronically mediated work in person and 0.5% did electronically mediated work entirely online;

Black workers accounted for 17% of all electronically mediated workers, whereas white workers accounted for 75% of these types of workers;

Compared with workers overall, people age 25 and over who did electronically mediated work were more likely to have a bachelor’s degree or higher.

Ultimately the findings do not provide any ground-breaking insights into non-traditional work which wasn’t already known, said Shelly Steward, research manager at the Aspen Institute Future of Work Initiative. She added that they are “in line with tax surveys.”

“It’s not that the BLS isn’t asking the right questions,” Steward said, “there is a lot of thought that went into them, it’s just really hard to get a rigorous measure to gauge this type of work.”
