This was the fifth 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 2018 they represented only 6%. The decrease in Portuguese emigration to Switzerland, however, shows a tendency towards deceleration: from -24% in 2014 to -5.7% in 2018.
