They are traditionally seen as being among the most hardworking and conscientious of students - perhaps even a little dull. So it might come as a surprise that economics undergraduates have been found to be the most promiscuous students on campus. A survey of 4,656 undergraduates found that economics students had nearly five sexual partners since starting university, compared to less than two for those studying environmental science. 

The study, conducted by the StudentBeans.com website, found that undergraduates studying economics had 4.88 sexual partners since starting university, with the next most promiscuous students studying social work, community care and counselling (4.7 partners).
