Considerable research effort has been invested in establishing the appropriate relationship between patterns of land distribution and political violence. In an article in the June 1988 issue of the Review, Manus I. Midlarsky proposed and tested a new measure of the distribution of land, which he called “patterned inequality.” He presented supporting evidence with data from Latin American and Middle Eastern countries. In this controversy, Midlarsky's analysis is challenged by Edward N. Mutter, Mitchell A. Seligson, and Hung-der Fu. They advocate an alternative measure of land inequality, test its effect on levels of political violence in Latin America, and find it wanting. In his rejoinder, Midlarsky offers new analytical support for his claims.
