Income inequality is one of the major issues in economic development, reflecting the unequal distribution of development outcomes across regions. This study aims to analyze the effect of road infrastructure, health infrastructure, education infrastructure, and economic growth on income inequality in East Java Province. This study employs a quantitative approach using panel data consisting of 38 regencies/cities in East Java Province during the period of 2015–2024. The analytical method used is panel data regression with the Fixed Effect Model (FEM) approach. The results indicate that road infrastructure, health infrastructure, and economic growth have a negative and significant effect on income inequality. Meanwhile, education infrastructure has a negative but insignificant effect on income inequality. These findings suggest that infrastructure development should be directed toward improving equal access and the quality of public services so that development benefits can be distributed more broadly among communities. This study provides implications for local governments in formulating development policies that support economic equality across regions.
