The report averages FBI crime data per capita from 2008 to 2011 for schools with over 10,000 enrolled.
ISU had an average of nine violent crime incidents a year, and last year, the university jumped to 236 larceny incidents.
Police Chief Bill Mercier says the reason for the ranking is because of those property crimes.
He also says the school encourages to report anything that happens on campus, which leads to higher numbers.
"I mean, we can always do better. Everyone can do better. If we have one crime, we have one crime too many. So we would always like to have zero crimes and that's kind of what we strive for, buts that's an ideal." said Mercier. "This is a nice place and it's a relatively safe place and I think our numbers compare pretty favorably to most other campuses of our size," said Mercier.
"These numbers, the headlines are kind of sensational, but the numbers don't help whole story. They're certainly not an indication, generally speaking of how safe or unsafe campus is."
One spot above ISU on the list of dangerous colleges, Ball State University ranked at number 12.
Two Illinois schools also appear, Western Illinois University came in at number 20, and the Carbondale campus of SIU is in the 15 spot.
