Although a high rate of urbanization and a high incidence of rural poverty are twodistinct features of many developing countries, there is little knowledge of theeffects of the former on the latter. Using a large sample of Indian districts from the1983–1999 period, we find that urbanization has a substantial and systematicpoverty-reducing effect in the surrounding rural areas. The results obtained throughan instrumental variable estimation suggest that this effect is causal in nature and islargely attributable to the positive spillovers of urbanization on the rural economyrather than to the movement of the rural poor to urban areas. This rural poverty-reducingeffect of urbanization is primarily explained by increased demand for local agriculturalproducts and, to a lesser extent, by urban-rural remittances, the rural land/population ratio, and rural nonfarm employment.
