Concepts inThe family and communication technologies
In human context, a family is a group of people affiliated by consanguinity, affinity, or co-residence. In most societies it is the principal institution for the socialization of children. Anthropologists most generally classify family organization as matrilocal (a mother and her children); conjugal (a wife, husband, and children, also called nuclear family); and consanguinal (also called an extended family) in which parents and children co-reside with other members of one parent's family.
