This was the second consecutive year that emigration to Switzerland significantly declined: -24% in 2014 and -19% in 2015. In a year when, on the contrary, the total number of migrants entering Switzerland increased, that recessive trend translated on a relative loss of importance of the Portuguese immigration: in 2013, the Portuguese accounted for 12% of migrants' arrivals in Switzerland, which fell to 9.4% in 2014 and 7.6% in 2015.
