Immigrants in Europe and North America do not receive the same pay as native-born individuals – even when performing the same job. This is documented in a major new study published in the prestigious journal Nature.
The study analyses data from 13.5 million employees and employers across nine countries: Canada, Denmark, France, Germany, the Netherlands, Norway, Spain, Sweden, and the United States. It shows that the majority of the pay gap can be explained by immigrants being concentrated in low-wage sectors and companies. The remaining difference – approximately 4.6% – is due to lower wages for the same work.
“Immigrants face significantly greater barriers to entering high-paying sectors and firms. This is the primary cause of the wage gap,” says CBS Associate Professor and study co-author Lasse Folke Henriksen.
Largest pay gaps among Sub-Saharan African immigrants
The study reveals that inequality varies substantially depending on the region of origin. Immigrants from Sub-Saharan Africa experience the largest wage gap at 26.1%, while those from Europe, North America, and other Western countries face a smaller gap of 9%.
There are also differences between individual countries. In Denmark, the wage gap stands at 9.2%, which is relatively low compared to, for instance, Canada and Spain, where the disparity is significantly greater (see table below).
In the six countries for which data on second-generation immigrants was available – including Denmark – the study examined whether wage patterns persist across generations. The results show that the difference decreases to an average of 5.7%, but remains particularly significant for descendants of immigrants from Africa and the Middle East.
