This study analyses the Effect of Socio-demographic factors on adolescents’ use of Reproductive Health Services in Delta State in six Local Government Areas of: Burutu, Bomadi (Delta South Senatorial District); Ughelli North, Udu (Delta Central Senatorial District); Ika South and Ukwuani (Delta North Senatorial District) through a survey design in a cross –sectional study with respondents equally drawn from the twelve schools with each having 125 respondents respectively. The use of equal protocol of 125 students from each class was based on the fact that equal sample of students were sampled from each class for equal representation of students in each school. The sample size of 1500 was drawn using the Rule of Thumb with stratified sampling technique used in order to ensure equal opportunity of participation of students (males and females). The study used systematic random sampling to select respondents from 125 secondary students comprising 63 male and 62 females, since the population of males was higher in most classes. The results indicate mixed outcomes. While there exists a significant relationship between classes (P-value=.000), ages (P-value=.000), ethnic group (P-value=.008) and income level of the parents (P-value=.000) of respondents, there is no significant relationship between: religion, sex and education of parents of respondents. The paper concludes that any programme or project promoting the use of ARHS must take into cognizance these factors in order to be successful in their efforts.
