At the beginning of 2019, Helsinki’s population included people with a total of 167 different nationalities. The number of foreign nationals living in Helsinki was 62,079. Of foreign nationals, 37 per cent were from EU countries and 13 per cent from elsewhere in Europe. 32 per cent were Asians, 12 per cent Africans, 3 per cent from North America and 2 per cent from South America. The largest group of foreign nationals, with 11,863 people, was Estonians, followed by Russian nationals (5,871 people), and Iraqi nationals (3, 518).

Many former Somali nationals have acquired Finnish citizenship: The number of residents with a Somalian background in Helsinki was three times higher than that of Somali nationals. There were also a lot more residents with a background in the former Soviet Union than Russian nationals. Many of them are Ingrians, i.e. ethnic Finns from Russia, who were granted the status of returnees, or their family members. On the other hand, the number of Estonian nationals was almost the same as that of residents with an Estonian background. The number of people with a Swedish background was even smaller than that of Swedish nationals. This is mainly explained by Finns born in Sweden, who have later moved to Finland.

Finnish citizenship was obtained by 3,057 foreign nationals in Helsinki in 2017. The number of people obtaining Finnish citizenship was clearly larger than in earlier years both in Helsinki and Finland as a whole. The largest groups obtaining Finnish citizenship were Somalis, Russians, Iraqis, and Estonians. In Finland as a whole, 12,219 foreign nationals who had been living permanently in the country obtained Finnish citizenship. Between 2000 and 2017, Finnish citizenship was granted to 27,000 people in Helsinki.
