It’s almost time to head back to school. So we’re going to fill you in on a new study about college majors - and how they affect what people can earn in the real world. Researchers at Georgetown University looked at 200 different majors, and the starting salary graduates earned in their first job after college.

The result: The two most popular majors - business and liberal arts – didn’t attract the best starting salaries. What did? Engineering, followed by computer science. In fact, petroleum engineering majors out-earned marketing majors by about 2 to 1. And a computer degree brought in $3 for every $1 earned by an education major.

In fact, grads with any type of technology degree have an easier time finding work. And there’s near-zero unemployment for people who graduated in geological engineering, chemical engineering or data management. What’s this mean to you?

Anthony Carnevale is the director of Georgetown's Center on Education and the Workforce.  He says every student should consider their future salary when they decide what to major in. Because they have to make sure they can earn enough to cover their student loans AND have money to live on.

But career development expert Rachel Brown says don’t just follow the money. You don’t want to hate going to work every day. You also should consider things like how much you’d enjoy your day-to-day responsibilities and how well the job fits with your values.
