This study is aimed at assessing flood vulnerability of Ibaji LGA of Kogi state, Nigeria. The factors considered in this research include socioeconomic activities, rainfall characteristics, land-use pattern, drainage density, slope, soil, and elevation. The Analytical Hierarchy Process (AHP) was used to establish the relationship between flood causative factors and their role in the occurrence as well as the vulnerability of communities within the study area. Each factor was assigned weight depending on the perceived role in the occurrence of flood within the study area. The factors considered in this research and their cumulative weights are rainfall (24.4%), Drainage Density (17.9%), Slope (18.5%), Elevation (17.4%), Land Use (11.8%) and soil (9.9%). The results of this study suggest that no single factor is responsible for the occurrence of flood in the study area, a combination of the factors assessed are responsible for the occurrence of flood. The degree of susceptibility of communities to flood in the study area varies among communities dependent on the factors that predominate within the community.
