Most dual nationals also have an Italian passport (23%), followed by French (11%) and German (9%) – all of which are neighbouring countries.
The Federal Statistical Office reported on Thursday that two-thirds of dual nationals acquired their Swiss citizenship through naturalisation, while only a third were Swiss at birth.
The share of dual nationals living in Switzerland has increased significantly since 2010, when they represented 14% of the whole population.
In 2018, Switzerland eased citizenship requirements for people aged 25 or under living in Switzerland who have a connection to the Alpine state.
