This paper investigated the effects of gender inequality, income inequality, educational inequalityand economic growth across continents of the world. Specifically, six continents consisting of Africa, Asia, Europe, North America, Oceania and South America were used. The study design was cross sectional in nature. Secondary source of information on gender inequality, unequal access to education as well as Gini coefficient as an intermediary for income inequality were obtained on six continents of the world from the UNDP Human Development Report 2021/2022. The retrieved data were disaggregated based on the six continents and analysed using Lease square regression to show the associations between gender inequality, income inequality, educational inequality and economic growth respectively. The sorted data was subjected to statistical analysis using IBM-SPSS Version 26. Kuznets and social justice theories served as the theoretical footings on which the study is premised. Findings revealed that inequality in education decreased the economic growth of Africa, Europe and North America. Also, gender inequality increased the economic growth of Asia and Europe. Additionally, Africa was the only country that showed increasing gender inequality was associated with decreasing economic growth. The study recommended that Africa leaders should put equity measures in place to reduce inequality in education as well as gender inequality to improve the economic growth of the continent. Again, leaders of Europe and North America should initiate educational equality policies to promote the economic growth of their continents.
