Earth Day 2019: Careers that Care for Our Earth

Next year will be the 50th Anniversary of Earth Day! The first Earth Day occurred on April 22, 1970, and I will show my age and admit that I clearly recall marching around my little campus on a blustery spring day in Topeka. Now, 49 years later, we want to celebrate Earth Day by highlighting some jobs that take care of our planet.

One way we keep track of jobs in the United States is through the Occupational Outlook Handbook which provides career information for hundreds of occupations. The Occupational Outlook Handbook was first published in 1949 to serve returning veterans of World War II. This year, the Handbook is 70 years old!

In honor of Earth Day, here are six earth-friendly career paths to consider:

BLS Local Data App Now Available for Android Devices

The wait is over! The BLS Local Data app — a mobile application that connects users with the data they need to know about local labor markets — is now available for Android devices. Search “BLS Local Data” in Google Play.

The BLS Local Data app, first released for iPhones last fall, uses the BLS API to present local data and national comparisons for unemployment rates, employment, and wages. You can search using your current location, a zip code, or a location name to find relevant data quickly without having to navigate through the huge BLS database. With one click, you can find data for states, metro areas, or counties.

BLS continues to partner with the U.S. Department of Labor’s Office of the Chief Information Officer to expand the features and data in the app. A second version is in development and will be available soon for both iPhone and Android devices. Version 2.0 will include employment and wage data for detailed industries and occupations. It also will have new charting functionality that will allow users to plot the historical unemployment rate time series for their local area of interest.

Check out the app and bring the wealth of local labor market data produced by BLS directly to your mobile devices!

Why This Counts: What Do We Know about Strikes and Lockouts?

Strikes and lockouts? Aren’t those 1940s-50s-60s economic activities? Sounds like we are taking a trip to the distant past with Sherman and Mr. Peabody in the WABAC machine. (For you younger readers, these characters can be found in the Adventures of Rocky and Bullwinkle and Friends, a TV show from the early 1960s.) BLS first collected data on labor and management disputes (work stoppages) in the 1880s. BLS has continuously published work stoppage information since 1947, for events covering at least 1,000 workers. Recently, high profile work stoppages by public school teachers and others have kept these types of activities in the news.

What are work stoppages?

The work stoppages program provides monthly and annual data on major work stoppages involving 1,000 or more workers and lasting one full shift or longer. For this report, BLS does not differentiate between strikes and lockouts.

  • Strikes are a temporary stoppage of work by a group of employees to express a grievance, enforce a demand, or protest the terms, conditions, or provisions of a contract.
  • Lockouts are a temporary denial of employment by management.

Detailed monthly reports from 1993 to the present provide the organizations and unions involved, along with the locations, industries, number of workers directly involved, and days of idleness.

Who uses these data?

Work stoppages provide media, researchers, labor relations specialists, unions, and government agencies with information about labor-management disputes. While the work stoppages program does not report on the nature of the dispute, identifying the details of parties involved helps users assess the impact of compensation trends, union membership and activity, and legislation.

Has work stoppage activity changed over time?

Since BLS began reporting on work stoppages, declines in union membership, the growth of the service industry, technological changes, and other factors have led to a significant reduction in the number of work stoppages. Between 1947 and 1956, there were 3,438 work stoppages. In the decade from 2007 to 2016, there were 143 stoppages. In 2017, there were 7 work stoppages, and in 2018 there were 20.

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

Decreases in the number of work stoppages and the number of workers involved are especially noticeable during recessions. These levels reached an all-time low at the end of the 2007–09 recession. In 1952, there were 2,746,000 workers involved in work stoppages, whereas in 2018 there were 485,000 workers involved.

Another way to evaluate the impact of work stoppages on the national economy is by looking at the number of days workers are away from work because of strikes or lockouts. The number of days of idleness reached a peak in 1959, at about 60,850,000 days. The second largest number was in 1970, with 52,761,000 of days of idleness. In 2018, there were 2,815,400 days of idleness. Number of days idle from work stoppages involving 1,000 or more workers, 1947–2018

Where are work stoppages most prevalent?

Of the 559 major work stoppages between 1993 and 2018, 423 occurred in private industry, 95 in local government, 40 in state government, and 1 in both state and local government. Most stoppages during that period, 458, occurred within individual states, while 101 occurred in two or more states. California, the state with the largest share of national employment (13.6 percent), had the largest share of work stoppages, 24.2 percent. Texas, which accounts for 9.6 percent of national employment, accounted for 2.9 percent of all work stoppages (excluding interstate and nationally reported stoppages).

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

These data also allow users to evaluate differences in the number of work stoppages by industry. From 1993 to 2018, there were almost as many stoppages in manufacturing (158) as the next two industries combined. Health care and social assistance had 83 work stoppages, while educational services had 79 work stoppages. Of the 79 educational services stoppages, 75 were in state and local government, with 50 occurring in local government and 25 in state government.Number of major work stoppages by industry, 1993–2018

Celebrating Women in STEM Occupations

International Women’s Day was first celebrated on March 19, 1911. During International Women’s Year in 1975, the United Nations began celebrating International Women’s Day on March 8.

In the United States, the first National Woman’s Day was observed on February 28, 1909. The Socialist Party of America designated this day to honor the 1908 garment workers’ strike in New York, where women protested against poor working conditions. Since President Jimmy Carter’s Presidential Proclamation in 1980, March has included a celebration of National Women’s History.

This blog celebrates women in the labor force, especially those working in STEM (science, technology, engineering, and math) professions.

Check this out: Earlier this year, to commemorate the 150th anniversary of the creation of the Periodic Table of Chemical Elements, we published our own Periodic Table of STEM Occupations!

But first some context

When President Carter issued his proclamation in 1980, 47.7 percent of women were employed, compared with 54.9 percent of women in 2018. For women ages 25 to 54, there has been an even greater increase in employment — from 60.1 percent in 1980 to 72.8 percent in 2018.

Women work in a variety of occupations. The largest number of women work as:

  • Registered nurses (2.8 million)
  • Elementary and middle school teachers (2.7 million)
  • Secretaries and administrative assistants (2.4 million)
  • Cashiers (2.4 million)

The occupations that overwhelmingly comprise women include:

  • Preschool and kindergarten teachers (97.6 percent are women)
  • Dental hygienists (97.1 percent)
  • Speech-language pathologists (96.0 percent)
  • Dental assistants (96.0 percent)

How are women doing in STEM occupations?

Three broad occupational groups have many STEM jobs: life, physical, and social science occupations; computer and mathematical occupations; and architecture and engineering occupations.

  • Nearly half of the people in life, physical, and social science occupations are women.
  • About 1 in 4 people working in computer and mathematical occupations are women.
  • About 1 in 6 people working in architecture and engineering occupations are women.

Here’s a look at women’s shares in more specific STEM occupations.

What else can you tell us about STEM jobs?

The Occupational Employment Statistics program provides a wealth of information about employment and wages annually for more than 800 occupations. The occupational employment and wage data below are for 2017. We will release the 2018 data on March 29, 2019.

The Occupational Outlook Handbook can help you find career information on duties, education and training, pay, and job outlook for hundreds of occupations.

Let’s highlight our data for several STEM occupations for all workers:

Computer Systems Analysts

  • National employment is 581,960, and the mean annual wage is $92,740.
  • California has the most computer systems analysts, with 72,980; New Jersey is one of the best paying states, at $105,750.
  • Computer Systems Analysts have a projected 9-percent increase in employment from 2016 to 2026 (as fast as average).

Industrial Engineers

  • National employment is 265,520, and the mean annual wage is $90,340.
  • Michigan has the most industrial engineers, with 28,460; Texas is one of the best paying states, at $108,330.
  • Industrial Engineers have a projected 10-percent increase in employment from 2016 to 2026 (faster than average).

Chemical Technicians

  • National employment is 64,550, and the mean annual wage is $51,010.
  • California and Texas have the most chemical technicians, with 6,450 and 6,350, respectively; Delaware is one of the best paying states, at $63,350.
  •  Chemical Technicians have a projected 4-percent increase in employment from 2016 to 2026 (slower than average).

Some final thoughts

These STEM occupations pay more, and sometimes significantly more, than the mean annual wage for all workers of $50,620. In 2017, the mean wage for STEM jobs was $91,310.

There were nearly 8.9 million STEM jobs in May 2017, representing 6.2 percent of U.S. employment. Employment in STEM occupations is projected to increase by 10.9 percent (faster than average) from 2016 to 2026. This growth is expected to result in 1.0 million new jobs.

Tracking the Changing Nature of Work: the Process Continues

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.

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

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.

Percent distribution of workers by age, May 2017

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.
