Аннотация:In this paper we present data on the altruistic behavior among rural Meru and urban mixed-ethnic children of Dar-es-Salaam of Tanzania, based on their decision-making in three sets of sharing games. Particularly, we examine the readiness of rural and urban African schoolchildren to take prosocial, sharing and fairness decisions; we also reveal to what extent these de-cisions are congruent towards friends and anonymous peers and test the gender differences in the decision-making. Our results provide another confirmation of the parochial altruism hypothesis.
