The Power Distance Index (PDI) indicates the extent to which power is distributed equally or unequally in a society. A high number represents greater power inequality. In more equal (low power) societies, there is less emphasis on status and formal power, relationships in organizations are more informal, children are expected to show initiative and speak up. In more unequal (high power) societies, power and status come from one’s family or from tradition. Communications are hierarchical, change comes more slowly, children are expected to be obedient.

Individualism (IDV) and its opposite, collectivism, refer to the degree to which individuals are integrated into groups (a high number represents a very individualistic society). In individualistic cultures the ties between individuals are loose: everyone is expected to look after himself or herself and his or her immediate family. In more collectivist societies, people are integrated into strong, cohesive in-groups, often extended families, from birth onward, and these groups continue protecting them in exchange for unquestioning loyalty. (The word “collectivism” in this sense has no political meaning; it refers to the group, not to the state.)
