The study comprehensively analyzed the nexus between economic growth, health expenditures, education, and the environment in Nigeria, using data obtained from Central bank of Nigeria and World Bank. By utilizing a robust dataset spanning from 1981 to 2021, the study employed autoregressive distributed lag (ARDL) approach to uncover intricate relationships. Results, both short-run and long-run analyses, reveal that health and education spending, and gross fixed capital formation positively correlated with economic growth. Conversely, the findings demonstrated that population growth and carbon dioxide emissions (CO2) exerted detrimental effects on economic growth due to the negative impact on the health of the working population. Additionally, the inverted U-shaped relationship between the macroeconomic footprint and income confirms the validity of Nigeria's Environmental Kuznets Curve (EKC) phenomenon. Lastly, the findings of this study hold important policy implications, emphasizing the need for technological advancements and innovative solutions to address the challenges associated with economic growth, health expenditures, education, and the environment in Nigeria. Policy measures promoting birth control through contraception and family planning should be embraced to effectively manage the country's rapidly growing population.
