The exponential growth rate of Nigeria population is a serious concern which must be checked in order to forestall population explosion from taking place in the country. The study therefore investigated the socioeconomic factors affecting utilization of family planning services among women of reproductive age in Owo local government area of Ondo state, Nigeria. It is a cross-sectional household survey which enlisted 401 women within the reproductive age (15-49 years) from four communities randomly selected from two wards of the eleven wards in the LGA. A structured questionnaire was used to obtain information from the respondents. Three levels of analyses (univariate, bivariate and multivariate) were carried out using descriptive statistics and logistic regression model. Considering the unadjusted model, maternal education, marital status, religion and cost of transportation to health centers were the significant predictors of contraceptive use. However, in the adjusted (multivariate) model only education significantly predicted the use of modern contraceptive. The study therefore concludes that a significant proportion of women with or without primary education were not using modern contraceptive, hence health information education is recommended for women in the LGA.
