2020. Economic performance is proxied into real income per capita and economic growth. The analytical method used is the Klassen typology, Williamson index, and historical convergence. Data processing with Klassen Typology shows that there is only one province in quadrant 1 and quadrant 2, namely Riau Islands Province and Riau Province. Most provinces belong to the potential quadrant. The results of the Williamson index illustrate a decrease in real GDP per capita inequality between regions on the island of Sumatra. This situation also reflects the emergence of the effect of economic convergence between provinces, where a slowdown in economic performance in one region is followed by economic development in other regions. This conclusion is strengthened by the historical convergence method, which shows a negative slope line. On the other hand, the provinces of Riau and Riau Islands, which are classified as rich, experienced a significant slowdown in growth. This line indicates that most of the relatively poorer provinces have high real per capita income growth performance, except for Aceh.
