Interdependence is the mutual reliance between two or more groups. In relationships, interdependence is the degree to which members of the group are mutually dependent on the others. This concept differs from a dependent relationship, where some members are dependent and some are not.
In an interdependent relationship, participants may be emotionally, economically, ecologically and/or morally reliant on and responsible to each other. An interdependent relationship can arise between two or more cooperative autonomous participants (e.g. a co-op). Some people advocate freedom or independence as the ultimate good; others do the same with devotion to one's family, community, or society. Interdependence can be a common ground between these aspirations.
