This study investigates the influence of demographic factors on undergraduates’ perceptions of courtship and its relationship with pre-marital sex, using the University of Abuja, Abuja as a case study. Through a descriptive research design, data were collected from 100 randomly selected undergraduates using a questionnaire. The findings reveal that demographic factors such as family background, peers, university environment, and social media significantly impact students’ perceptions of courtship, consequently influencing their engagement in pre-marital sexual behaviors. The study underscores the importance of understanding these influences to address the challenges associated with pre-marital sex among undergraduates in Nigeria. Recommendations are made to mitigate the negative effects of these influences on students’ perceptions and behaviors regarding courtship and pre-marital sex.
