The choice of these two domains was to give a thorough assessment economic impact of women’s education. The Augmented Dickey-Fuller (ADF) was used to test for the stationarity of variables. The Autoregressive Distributed Lag (ARDL) bound test with the aid of data obtained from World Bank indicators was employed for the analysis. The analysis revealed that the more women with secondary and tertiary education, the better the economic growth and child welfare in Nigeria. Hence, the paper concluded that the government should make and implement appropriate policies to boost women’s education enrolment at all levels.
