America’s multiple jobholders, visualized

In this post, we continue to study a very interesting subset of the publicly available CPS microsample data: people working multiple jobs. We have already seen the dynamics in gender distribution as well as education patterns.  Today we focus on their industries.

It shouldn’t come as a surprise that some jobs are much more physically and mentally demanding that others. For example, it’s hard to imagine someone who works in mining and also has a second job. As seen on the chart below, the Mining supersector is indeed at the very bottom of the list.

Educational Services are (not very surprisingly) on the other end of the spectrum, at more than 8 percent. Another interesting observation is that while most industries don’t show a statistically significant difference between genders, some do. Namely, the percentage of multiple jobholders is greater among women in Construction (which, again, is perfectly reasonable). Men lead the count in Health Care and Educational Services.

Of course, that’s literally only half of the story. While we see the numbers for each sector, that tells us nothing about the second job. Since the number of possible combinations is large, that requires a more complex visualization method. Click on the chart below to see the larger, interactive version.

Differences between sectors become even more apparent here. Take, for example, Finance and Insurance. Somewhat unsurprisingly, not too many people (just over 4,000) have both primary and secondary jobs in this sector. More people prefer to get a second job in Retail Trade or Accommodation and Food Services (14,300 and 8,200, respectively).

On the other hand, those who have primary jobs in the Accommodation and Food Services sector prefer to get a similar second job (almost half a million workers). That's much more than even people opting for a second job in the most popular sector: Retail Trade.
