Background: Nigeria has one of the fastest-growing populations in the world due to its high fertility rate coupled with a low contraceptive prevalence rate (CPR) which is currently 17%. One of the factors responsible for this is a lack of male involvement (MI) in family planning (FP). Aim: This study was conducted to determine and compare the level of MI in FP and the correlates of MI in FP in urban and rural communities of Sokoto State, Nigeria. Materials and Methods: A comparative cross-sectional study was employed to investigate 846 married men selected via a multi-staged sampling technique. Data was collected using a structured interviewer-administered questionnaire and was analyzed using IBM^® SPSS version 23. Results: The contraceptive prevalence rate was 49.4% in urban areas and 46.3% in rural areas (p= 0.371). More than half (58.4%) of the respondents in the urban areas and a little below half (48.2%) of those in the rural areas were highly involved in FP (p= 0.003). The correlates of MI in FP in both groups were the occupation of the respondents and their spouses, social class and ever use of a FP method. Conclusion: The CPR was good, but MI in FP was low in the two areas. Sokoto State Government and the Local Government Areas should continue to raise awareness and provide information on the benefits and the need for more males to be involved in FP. This could be done through the use of information, education and communication materials and public enlightenment programmes.
