There are several ethnic groups in Afghanistan which traditionally lead a peripatetic life. This means they are nomadic and their main occupations centre around providing services to the settled populations they travel among, like peddling particular goods or performing music. In this way, they contrast both with the settled population and with the pastoralist nomads. They are of low social status and are known to outsiders as Jats, a derogatory term that none of the groups use as a self-designation.
