Moving forward into the 20th century, in tandem with new thinking in the , folklorists also revised and expanded their concept of the folk group. By the 1960s it was understood that social groups, i.e. folk groups, were all around us; each individual is enmeshed in a multitude of differing identities and their concomitant social groups. The first group that each of us is born into is the family, and each family has its own unique family folklore. As a child grows into an individual, its identities also increase to include age, language, ethnicity, occupation, etc. Each of these cohorts has its own folklore, and as one folklorist points out, this is "not idle speculation… Decades of fieldwork have demonstrated conclusively that these groups do have their own folklore." In this modern understanding, folklore is a function of shared identity within any social group.
