4. This is a relatively recent development. Birthright citizenship in municipalities (Heimatrecht) in late 19th century Austria and Germany was used to restrict internal migration by denying poverty relief and access to local public services to citizens residing outside their municipality of birth. Switzerland's Bürgergemeinden, in which membership is acquired at birth, is a historical remnant of this system. Today's hukou system in the Peoples' Republic of China is an extreme case of local birthright citizenship as an instrument of exclusion from social welfare. This is based on ius sanguinis so that rural hukou status is even inherited by the second generation of migrant-descent born in cities.
