Although often associated with developing countries, illicit activities or undocumented workers, the informal labor market is much broader than many would imagine. In fact, people from all walks of life participate in a wide array of legitimate business ventures that are part of the informal economy. So, how big is the U.S.’s informal labor market, and who participates in it?

What Is the Informal Labor Market?

There is no unique definition for informal employment. However, a generally accepted way to define it is by considering individuals (and their employers) who engage in productive activities that are not taxed or registered by the government.1

Though this type of work has always existed – picture the fruit vendor at the farmers’ market who only accepts cash for payment – the expansion of online platforms that facilitate these arrangements has increased their visibility and fueled their popularity.

Measuring the Informal Labor Market

Numerous surveys have surfaced lately in an effort to better understand the fringes of the U.S. labor market. Though methodologies differ (as do the specific questions these surveys attempt to answer), comparing the results helps shine a light on the sometimes elusive nature of the informal labor market.

Survey of Informal Work Participation

For example, the Survey of Informal Work Participation within the Survey of Consumer Expectations revealed that about 20 percent of non-retired adults at least 21 years old in the U.S. generated income informally in 2015.2 The share jumped to 37 percent when including those who were exclusively involved in informal renting and selling activities.

When breaking down the results by the Bureau of Labor Statistics (BLS) employment categories, about 16 percent of workers employed full time participated in informal work. Not surprisingly, the highest incidence of informal work was among those who are employed part time for economic reasons, with at least 30 percent participating in informal work. Also, at least 15 percent of those who are considered not in the labor force by the BLS also participated in informal work.
