Dual citizenship

Persons aged 15 or over with dual citizenship represented 18% of the Swiss permanent resident population (967 000 people) in 2018. Within this population of dual nationals, 65% obtained Swiss nationality through naturalisation, whereas 35% acquired it at birth.


Dual citizenship (also called dual nationality) is when a person has at least two different nationalities, if which one is Swiss nationality. People with Swiss nationality as well as that of another country (dual nationals) are considered as Swiss in the statistics. They may be Swiss by birth (born to one Swiss parent and one foreign national parent) or through naturalisation.
