The study looked at why non-EU immigrants in Belgium struggle to find jobs compared to locals. They found that differences in education, family size, and where they live play a big role. For EU immigrants, most of the job gap is due to these factors. But for non-EU immigrants, only a third of the gap is explained by this. Over the years, the impact of education differences has become more important, showing that recent non-EU immigrants have lower education levels compared to locals.
