The projection for the population with a foreign mother tongue in Helsinki and the Helsinki Region was drawn up in the autumn of 2015 in cooperation between the statistical and research authorities of the cities in the Helsinki Metropolitan Area. By 2030, depending on the number of asylum seekers in the coming years, the number of population with a foreign mother tongue in Helsinki is estimated to grow to 164,000–170,000 people, or about 23 per cent of the total population. In the Helsinki Region there would be 350,000 foreign-language speakers, making up about 21 per cent of the total population.
Men are expected to remain in a small majority in the population with a foreign mother tongue in Helsinki. In 2030 every fourth child aged 0–15 years and more than every fourth person of working age would have a foreign mother tongue. The number of foreign-language speakers aged 65 and over is estimated to grow fastest but they would still account for less than 10 per cent of the whole population of that age in 2030. The biggest language group in Helsinki in 2030 is expected to be those who speak languages of the Middle East or North Africa as their mother tongue.
