Demographic and social differentiation among northern Peruvian peasants.

"In this paper, [the authors] apply the concepts of demographic and social differentiation to the analysis of inequality among rural households in the northern Peruvian department of Cajamarca. While [they] demonstrate that social rather than demographic differentation is the more important process in this area, [they] illustrate the complementarity of Chayanov's methodological analysis of the family life cycle with a Marxist class-theoretical framework. Both enrich the study of patterns in the agricultural sector of household labor use, family structure and composition, and income inequality."
