Anti-Semitism appears to still be a major issue in U.S. colleges, according to a new poll by the National Demographic Survey of American Jewish College Students. 

The survey polled 1,157 self-identified Jewish students who attend 55 different colleges across the U.S. in spring 2014. More than half of the respondents - 54 percent - reported "instances of anti-Semitism on campus during the first six months of the 2013-2014 academic year," according to a news release. 

The National Demographic Survey of American Jewish College Students survey was led by researchers Barry Kosmin and Ariela Keysar from Trinity College. 

"The patterns and high rates of anti-Semitism that were reported were surprising," Kosmin said in the release. "Rather than being localized to a few campuses or restricted to politically active or religious students, this problem is widespread. Jewish students are subjected to both traditional prejudice and the new political anti-Semitism."

Keysar added that women were more likely to report anti-Semitism attacks than men, which she said suggests that they feel "more vulnerable" on campuses. 

The report on the survey urges colleges to revisit their policies to try and solve this issue. 

The survey was released in February 2015 by Trinity College.
