Dual citizenship

Persons aged 15 or over with dual citizenship represented 19% of the Swiss permanent resident population (999 000 people) in 2019. 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 defined as having at least two different nationalities. In this analysis, however, only persons who hold Swiss citizenship in addition to one (or more) foreign citizenship are taken into account. These people are considered Swiss in the statistics. They may be Swiss by birth (born to one Swiss parent and one foreign national parent) or through naturalisation.
