Sedentism
In cultural anthropology, sedentism (sometimes called sedentariness) simply refers to the practice of living in one place for a long time. The majority of the Western population belong to sedentary cultures. In evolutionary anthropology and archaeology, it takes on a slightly different sub-meaning and is often applied to the transition from nomadic society to a lifestyle that remains in one place permanently. Essentially, sedentism means living in groups permanently in one place.
