This was the seventh consecutive year in which emigration to Switzerland declined significantly, after reaching its peak in 2013. Since 2001, the number of Portuguese entering Switzerland has not been so low. The recessive trend translated into a relative loss of importance of Portuguese immigration: while in 2013 the Portuguese accounted for 12% of migrant arrivals in Switzerland, in 2020 they represented only 5.5%. The decrease in Portuguese emigration to Switzerland is accelerating again: from -3.3% in 2019 to -10.7% in 2020.
