Individualism index: The index measure the extent to which a society is individualistic. Individualism refers to a loosely knit social framework in a society in which people are supposed to take care of themselves and their immediate families only. The other end of the spectrum would be collectivism that occurs when there is a tight social framework in which people distinguish between in-groups and out-groups; they expect their in-groups (relatives, clans, organizations) to look after them in exchange for absolute loyalty.
