Population Growth and Economic Growth Nexus: Evidence From Nigeria
Year: 2025
Type: article
Abstract: This study examined the relationship between population growth and economic growth in Nigeria. The study employed annual time series data obtained from the CBN Statistical Bulletin and World Bank Data base for the period 1983 to 2022. The specific objectives that the study achieved include analyzing the effect of population growth on Nigeria's economic performance and determining the causal relationship between population and economic growth in Nigeria. The study employed the ADF unit root test, ARDL Bounds test for cointegration, and the error correction mechanism. The result of the unit root test revealed that the variables were stationary at a mixed order of integration (levels and first difference), while the ARDL Bounds test revealed the presence of a long-run relationship. Findings of the study further revealed that the population growth rate exerted a positive and significant long-run effect on economic growth within the study period. The error correction mechanism indicated that 42.31 % of the short-run disequilibrium is corrected in the long-run. The result from the Granger causality test also showed that there is a unidirectional relationship running from population to economic growth during this study. The paper recommended that the Nigerian government should embark on sensitization programs to enlighten the Nigerian populace on the need to check the fertility rate and that policies that enhance family planning should be adopted to put the population growth in check in Nigeria.
