Ethnographers typically maintain their connection to the community they study and may return to it several times to see how community life has changed. for example, margaret mead first described her fieldwork in growing up in new guinea, detailing her study of the manus, a new guinea people still mostly untouched by the outside world when she visited them in 1928. she lived in their noisy fishing village of peri at a pivotal time—after world war i was over but before missions and global commerce had begun to change their lives. she continued her relationship with this same village for 50 years until her death, and it her to describe how these villagers maintained their unique cultural values even with increasing global influence. what is the term used to describe this type of ethnographic research?
