It investigates the effects of changes in the urban-rural income ratio and within-sector inequalities on the Kuznets process of urbanization. This study also examines urbanization and expenditure inequality in Indonesia using household-level data for 1996-2018. Our analysis reveals that if the urban-rural income ratio is relatively small while the urban-rural difference in income inequality is relatively large, then overall income inequality is likely to increase for a longer period of time as urbanization proceeds. Conversely, if the urban-rural income ratio is relatively large while the urban-rural difference in income inequality is relatively small, then overall income inequality is likely to peak at earlier stages of urbanization. Our analysis also reveals that the contribution of urban inequality to overall income inequality tends to increase as urbanization proceeds, though there may be some fluctuations due to changes in within- and between-sector inequalities. In Indonesia, the share of urban households has risen gradually from 36% to 55%. However, no systematic relationship is observed between the share of urban households and overall expenditure inequality, meaning that Indonesiafs household-level data does not support the Kuznets inverted-U hypothesis. However, Indonesiafs household-level data shows that urbanization has been associated with a rising contribution of urban inequality and a declining contribution of between-sector inequality.
