Beginning in the 1960s, a further expansion of the concept of folk began to unfold through the study of folklore. Individual researchers identified folk groups that had previously been overlooked and ignored. One notable example of this is found in an issue of the "Journal of American Folklore", published in 1975, which is dedicated exclusively to articles on women's folklore, with approaches that had not come from a man's perspective. Other groups that were highlighted as part of this broadened understanding of the folk group were non-traditional families, occupational groups, and families that pursued the production of folk items over multiple generations.
