Dual citizenship

In 2022, 20% of the Swiss permanent resident population aged 15 and over had a dual citizenship (1 095 000 people). Among the population of dual nationals, 65% obtained Swiss nationality through naturalisation, whereas 35% acquired it at birth.



The term dual citizenship generally refers to having at least two different nationalities. In this analysis, however, only persons who hold a foreign nationality in addition to their Swiss nationality are considered dual nationals. In official statistics, these people are counted among the Swiss population, whether they are Swiss by birth (born to one Swiss parent and one foreign national parent) or through naturalisation.
