The ongoing insurgency and banditry in northern Nigeria and the government's harsh attempts to put it down have resulted in a wave of refugees and internally displaced people. Increase in population density and the migration of displaced people into places that are thought to be relatively quiet are prominently causing significant security concerns. With particular reference to the city of Ilorin, this study investigates the role of internally displaced people and community concerns in connection to national security and their repercussions. The study showed that the state's failure to provide security and deal with residents' socioeconomic problems contributed to the instability that drove large population displacement. Losses of life, insecurity, population relocation, intolerance toward other ethnic and religious groups, the operation of the militant groups and most importantly economic disasters are the consequences of these unfavorable tendencies, as this article has discovered. The findings of this study shows that the government's response to the situation of internally displaced people in the nation has been patchy, with no long-term fix in sight. Additionally, the dilemma of internally displaced people severely impedes the region's growth. This paper consequently promotes the establishment of offices for these displaced people's representatives by including the affairs of internally displaced people at the local government level. As an option to dealing with the problem of internally displaced people in the nation, increasing funding for national security among residents would improve security in Ilorin metropolis.
