A national survey of college freshmen drew headlines this week for results indicating that emotional wellbeing is the lowest it's been since the tracking began three decades ago. 

But the report released by UCLA's Higher Education Research Institute touched on many other topics.

In a nutshell: Students are partying less, and are focused on earning credentials.

More than 60 percent of respondents said they either never attend parties or do so less than an hour a week. In 1987, that was just 24.3 percent.

The number of students who party six or more hours a week dropped from 34.5 percent in 1987 to 8.6 percent in 2014, the survey said.

Alcohol and tobacco use are down. The survey did not ask about illegal drugs.

Meanwhile, the survey found that students have higher educational aspirations than before. More than 40 percent want to earn a master's degree, while one-third want to earn a doctorate or professional degree.

In the 1970s, those percentages were in the 20s.

Today's tight, competitive job market is likely behind the change, according to Kevin Eagan, interim director of the annual survey research program.

Lastly, the survey corroborated the notion that college students are more left-leaning than the population at large.

Though nearly half of respondents rated themselves "middle of the road" politically, more than 80 percent support same-sex marriage and two-thirds support government action on climate change.
