The days of working the same 9-to-5 job for 40 years are a fading memory. Work today may involve multiple part-time jobs, working from home, obtaining work through a mobile device, and changing jobs frequently. The so-called “changing nature of work” is already here, and at the U.S. Bureau of Labor Statistics we are trying to keep up with this new world.

One of our primary sources of information on Americans’ labor market activity is the Current Population Survey (CPS), a monthly survey of households that provides a real-time snapshot of the share of the population who are employed and unemployed. These data are complemented by other BLS programs that focus on labor turnover, how Americans spend their time, details about local labor markets, and other topics.

But how well do these programs track nontraditional forms of employment, including short-term assignments, platform work, temporary help, and jobs so new and different we haven’t even named them yet? BLS has been working on these issues for many years. Let’s consider a few timely questions and see how BLS has responded.

Not all jobs are permanent. What do we know about jobs that are not expected to last?

Throughout its history, BLS has been exploring perceived changes in the nature of work. For example, an article in the October 1996 Monthly Labor Review described “…reports of corporate downsizing, production streamlining, and increasing use of temporary workers…” as raising questions about “…employers’ commitment to long term, stable employment relationships.” This article, and many others in the same issue, went on to introduce the first “Contingent Worker Supplement” (CWS) to the CPS. Supplements such as this are additional questions on specific topics generally asked once (as opposed to every month) of CPS households.

The CWS asks about jobs that are not expected to last, as well as alternative work arrangements, such as working as an independent contractor or through a temporary help agency. While not an ongoing BLS program, we received funding to conduct the supplement in 1995, 1997, 1999, 2001, 2005, and 2017. This allows us to track contingent work over time. In May 2017, there were 5.9 million contingent workers – those who did not expect their job to last. This represented 3.8 percent of the total employed. Twelve years earlier, a slightly higher percentage, 4.1 percent, did not expect their job to last.

Editor’s note: Data for this chart are available in the table below.

How many people are in different types of jobs, such as independent contractors?

The CWS also included questions to identify people who were in four types of alternative work arrangements:

Independent contractors

On-call workers

Temporary help agency workers

Workers provided by contract firms

The most prevalent of these arrangements was independent contractors. The 10.6 million independent contractors identified in May 2017 represented 6.9 percent of the total employed.

Does BLS have a measure of the “gig” economy?

BLS does not have a definition of the gig economy or gig workers. In fact, researchers use many different definitions when they talk about the gig economy. You may think of a gig as something your high school band played on a Saturday night. Or today you might consider your ride-share driver as performing a gig. Classifying workers as gig could get very confusing. For example:

A plumber or electrician may be on the payroll of a contracting company on the weekdays and obtain individual jobs through an app on the weekend. Gig worker?

A substitute teacher in one school district may obtain assignments and pay through traditional means, while the neighboring district assigns and pays workers through an app. Is one a gig worker?

Confused? So am I. To repeat, BLS does not have a definition of gig. Definitions developed by others may overlap with contingent workers and some of those in alternative employment arrangements in the CWS. Rather than try to develop such a definition, BLS chose to focus new questions narrowly, as you will see in the next section.

What about work obtained through an app?

In preparing for the 2017 CWS, and knowing the interest in work obtained through an app on a phone or other mobile device, BLS added four questions about short jobs or tasks that workers find through an app or website that both links them with customers and arranges payment. Separate questions asked about in-person work (such as driving for a ride-sharing company or providing dog-walking services) and online-only work (such as coding medical records). At BLS, we call these jobs “electronically mediated employment.”

While BLS conducted some testing of the questions on electronically mediated employment and vetted them with a variety of stakeholders, the results made it clear that people had difficulty understanding the questions. This effort resulted in many false-positive answers, such as a surgeon who said all of his work was obtained through an app. BLS used companion information, where available, to recode responses. To be completely transparent, BLS published both the original and recoded data, but we encourage data users to focus on the recoded information. These results indicate that 1 percent of the employed in May 2017 – about 1.6 million people – held electronically mediated jobs. A slightly higher number of workers (990,000) held in-person jobs than online-only jobs (701,000). Note that some workers indicated they had both types of jobs.

Compared with workers overall, electronically mediated workers were more likely to be ages 25 to 54 and less likely to be age 55 and older.

Editor’s note: Data for this chart are available in the table below.

Maybe these “app” jobs are a second job. Do we know how many people hold more than one job?

We get information from the CPS each month on the number of workers who hold more than one job. In 2018, there were 7.8 million multiple jobholders – about 5.0 percent of total employment in 2018. That’s around the same share of employment it has been since 2010, but it was below the rates recorded during the mid-1990s, which were above 6.0 percent.

With all these new types of work, is the BLS monthly employment information missing anyone?

As noted, the CPS is an authoritative source of labor market information and has provided consistent data for over three-quarters of a century. But BLS is always looking to improve its measures, and there are other data sources that can supplement the CPS. For example, the American Time Use Survey obtains information about an individual’s activities during a 24-hour period. Among the categories that may be identified are “income-generating activities,” such as making pottery for pay, playing in a band for pay, and mowing lawns for pay.

Recently, BLS looked at people who were not counted as “employed” but who participate in income-generating activities. The research suggested that between 657,000 and 4.6 million people participated in income-generating activities but were not otherwise counted as employed in the survey. Given that total employment is around 155 million Americans, this undercount ranges from 0.4 to 3.0 percent of the total.

The study also examined the extent that employed people who did informal work in addition to a regular job might not be correctly classified as multiple jobholders. The research found that reclassifying workers misclassified as single jobholders would increase the number of multiple jobholders somewhere between 3.0 percent and 20.7 percent.

What more is BLS doing to improve labor market measures?

So, yes, BLS is doing a lot to improve our labor market measures, and the work continues. We know there is likely a small number of people who are not counted as employed yet perform income-generating activities. We know that definitions and concepts may need to be updated from time to time. We know that some terms, like “gig,” are not well defined and mean different things to different people. And we know it is not easy to define or identify electronically mediated employment.

Given all this, we continue to move forward. BLS has contracted with the Committee on National Statistics, part of the National Academies of Sciences, Engineering, and Medicine, to convene an expert panel to address these issues and provide recommendations to BLS. This work began in late 2018 with a report due in early 2020. BLS will review the recommendations and, resources permitting, develop plans to test any new concepts or questions.

There’s been interest in emerging types of work for many years. It’s also a moving target, as the “changing nature of work” keeps changing. BLS has provided gold-standard data on America’s labor force for many years and will continue to research and refine and improve.
