Children from rural and semi-agricultural communities are more cooperative than children from urban or westernized cultures (see Eisenberg & Mussen, 1989, for a complete review). A cross-sectional study of 433 youth (5-22 years old) from Mexican villages and small towns, youth were more cooperative, helpful and more likely to avoid conflict than middle class Mexican (n=60), Mexican-American (n=155), or Anglo-American (n=215) children (Kagan, Knight, & Martinez-Romero, 1982). In addition, in a cross-sectional study of 20 groups of 9 - 11 year old children, children from kibbutzim in Israel were more helpful than their urban counterparts (Shapira & Lomranz, 1972). Eisenberg and Mussen (1989) argue that children from urban areas tend to be more competitive and less prosocial than children from other regions.
