Nigeria is currently the world's sixth most populous country. However, empirical research on the impact of this growing population on economic growth is divided. This study adds to existing research on the economic effects of Nigeria's rapid population growth. This study used a qualitative research design because it relied on secondary data gathered from books, journal papers, and online sources. Its content was examined in light of the objectives of the study, and Malthusian theory serves as the study's foundation. The majority of Nigeria's development issues, according to the study's findings, can be directly or indirectly linked to the country's rapid population growth. This study thus urges, among other things, the need for an all-encompassing mechanism that will address issues of conflict and insecurity, migration and displacement, access to education for girls, and proper regulation of infrastructure development, as well as the undiluted conservative ideology whereby many, especially in Nigeria, see population growth as the key to control of political power and resources that should be thrown away in favor of a more effective and functional system.
