This study aims to explain the condition of income inequality in ten provinces on the island of
Sumatra by using four independent variables, namely Population Number, ADHK GDP, Poverty
and Human Development Index in 2013-2023. The data was then analyzed based on the panel data
regression method procedure. The results obtained from the regression analysis of panel data are
that the Fixed Effect Model (FEM) is the most appropriate approach to explain the influence of
variables bound to free variables in this study. Based on the validity test of influence or t-test, it is
known that the variable that has a significant effect on the income inequality of ten provinces on
the island of Sumatra in 2013-2023 is the Population variable with a negative coefficient
direction.
