Higher-educated people are more likely to have a second job

As we found in an earlier post, women are notably more likely to have a second job than men. It also appears that there’s a clear geographical pattern for the popularity of having more than one job.

However, there are other factors that influence the desire and ability to have an additional source of income. One of them is education.

On one hand, people with college degrees are less likely to have a job requiring manual labor, which probably makes finding a second job easier for them. At the same time, their wages are higher, so they are less likely to require an additional source of income. Let’s look at the chart below.

People with more than one job by education status

As you can see, about 2 percent of all people in the workforce work multiple part-time jobs, regardless of their education level (though there is a small trend here). More importantly, it appears that higher-educated people are much more likely to have both a full-time job and a part-time one. The percentages range from 2.1 percent for people without a high-school education to 4.7 percent for people with a doctorate degree. In total, 7.3 percent of all doctorate degree holders have multiple jobs of any kind.

Another interesting observation can be drawn from the map below. There seems to be a clear geographical pattern for the percentage of people with at most a bachelor degree having multiple jobs. At the same time, the map looks significantly more random for higher-educated workers. It is especially noticeable for southern states: while the former number ranges from 3 to 4 percent, the latter shows much more variation. Louisiana, Mississippi and Alabama all show numbers around 8 percent, while in Texas and Georgia the ratio is as low as 5 percent.

People with more than one job by state

Note also that the percentage of higher-educated people having a second job is higher in virtually every state (the only exception is Nebraska - but the difference is not statistically significant there).
