This article investigates labour market segmentation of EU-13 workers in Sweden. Labour market segmentation is a driver of income differences between natives, EU-15 migrants and EU-13 migrants in many EU member states. There are, however, indications that labour market inequalities as a result of segmentation among EU-13 migrants is less pronounced in Sweden. Previous research, both quantitative and qualitative, has shown surprisingly low levels of labour market segmentation among the employed. The structural differences on the labour market has, instead, been between the employed and unemployed, with a large employment gap between natives and all migrant groups including EU-13 migrants. We address the functional integration in the labour market from a longitudinal perspective, using several quantitative indicators to measure the degree of labour market segmentation. Natives and other migrant groups (EU-15 and refugees) are used as reference groups. Our results shows a low but increasing labour market segmentation among the employed born in EU-13 countries. The dissimilarity between employed natives and EU-13 workers is increasing, especially among men. Men from EU-13 countries is the only category where the occupational position has deteriorated. From having a similar occupational position as EU-15 migrants in 2007, their position in the labour market in 2015 is more similar to the refugee group. This development is driven by a large increase of Polish construction workers on the Swedishlabour market.
