The downward trend that had been observed since 2014 was interrupted in 2021, with the number of Portuguese arrivals in Switzerland growing slightly (+1.8%), indicating a stabilizing trend in the number of Portuguese arrivals in Switzerland. Since 2001, the number of Portuguese entering Switzerland has not been so low. The recessive trend of the last years has translated into a relative loss of importance of Portuguese immigration: while in 2013 the Portuguese accounted for 12% of migrant arrivals in Switzerland, in 2021 they represented only 5.3%.
