Determinants of Urban Sprawl: Evidence from Indonesia Andrea Civelli * Arya Gaduh † University of Arkansas ‡ October 2018 PRELIMINARY - Please do not cite Abstract In many developing countries, rapid urbanization often led to an urban expansion pattern that exhibit the sprawling patterns observed in developed country. However, we know little about the determinants of urban sprawl in developing countries. We study the determinants of urban sprawls in Indonesia between 2000 and 2010. We combine a new spatial dataset on urban built-ups in East Asia produced by the World Bank with Indonesia’s village census and other satellite data on climate, geographic characteristics, and agricultural yields. We study the role of geographic and climatic factors, as well as socio-economic variables and amenities in determining the pattern of urban expansion and sprawling. Interestingly, we find significant differences in the determinants of sprawl between regions at different stages of economic development within Indonesia.
