One thing we know about Millennials: They are hungry to work. Most have a college degree, and they already account for about one third of the workforce today.

Yet, what we might not quite grasp is which jobs they are actually taking out of college and what motivates them to pursue those jobs. A recent study by  Data USA commissioned by  Deloitte that comes out next week finds that there are two jobs Millennials are taking more often, and two they are avoiding.

The two jobs they take the most? Not a big surprise, but they are entering the  military and the food service industry in record numbers. As Data USA suggested, they pick the military because of the requirements for service--only 20 years to an early retirement, for example. The military has high physical standards only Millennials can meet with ease and the military is more aggressively pursuing this age group.

For food service, it's a bit of a no-brainer. The jobs are easier to find...and easier to land. The average income is only $16,202, and Data USA found that the gender split is roughly even--although there are slightly more women working at companies like McDonald's and Burger King than men. However, when you need a job, the food service industry at least allows Millennials to get a quick paycheck. And, it adds a little experience beyond "captain of the intramural league" to a resume.

Now for the big surprise. Millennials are not landing as many management jobs. This might have something to do with their experience, but many of the people in the age group went to management school and have the right credentials. My guess is that they are not drawn to the role quite yet because of the higher stress load. They prefer being individual contributors and don't want the pressure. Data USA found that the typical male college-educated Millennials is three times more likely to work in the food-service industry than any management role. That would seem to suggest that Millennials are not pursuing leadership position as much as other age groups.

One takeaway for this stat is that we might not fully understand why Millennials are starting companies. They seem to avoid leadership roles, even if there is a clear indication that they are starting companies more than baby boomers right now. My guess is that Millennials start companies not because they want to be in charge of anything or anyone but because they want the freedom and higher income.

The second least popular job among Millennials is perhaps the biggest surprise. If it has anything to do with the transportation industry, you probably won't find Millennials in that role. Data USA suggested that the unionization in this field protects older workers. And, there's a push with autonomous driving and and other automations in the transportation sector, so when older workers retire, they might not be replaced by a Millennial. They'll be replaced by a robot.

What do you think? Have you seen more workers in other fields besides the military and food service? Do you see Millennials taking management jobs and driving trucks? Post in comments if you disagree with the data, which is culled from public records.
