„On average across OECD and partner countries where at least 5 % of 15-29 year-olds are foreign-born, one-quarter of foreign-born 15-29 year-olds who arrived in the country after the age of 15 are neither employed nor in education or training (NEET) compared with only 15 % of those who arrived by this age.“
