What role does integration play in reducing disparities in the labour market between ethnic minority and white majority populations? We shed light on this question by comparing the socio-economic positions of ethnic minorities in co- and inter-ethnic partnerships. We implement propensity score matching techniques to account for selection bias. We find that ethnic minorities in co- and inter-ethnic unions are rarely comparable and a large part of the labour market differences is explained by their individual socio-demographic characteristics. Finally, having a white majority group partner affects the occupational position and labour market participation of only some groups of women.
