This paper examines ethnic income inequality in Singapore from the perspectives of labour‐market segmentation and human capital. The findings of this study show that neither perspective is useful in explaining ethnic income inequality in Singapore. Further, the analysis shows that educational differences among the Chinese, Indians and Malays account for very little of the income gap. Much of the income difference is due to discrimination. The source of this discrimination lies in the segregation of ethnic minorities in lower‐paying jobs and occupations across all industries, reflecting Chinese domination in the economic and political spheres.
