Along with the social structure differentiation and the urbanization in China,the heterogeneity of migrant workers is increasing. This paper focuses on the impact of income growth and household registration attributes on the nutrient consumption of migrant worker's family in urban areas,and explores the differences in nutrient consumption when the household registration and income growth are different. The results show that income growth and household registration difference have significant impacts on the nutrient consumption of migrant workers' families. The income elasticities of energy,protein and fat demand for migrant worker's family are 0.592,0.605 and 0.553,respectively. In the case of keeping other factors unchanged,the per capita daily energy,protein and fat consumptions of the local migrant worker's family are 19.72%,18.29% and19.36% higher than those of the non-local migrant worker's family. The positive effects of income growth on the energy,protein and fat intake of non-local migrant worker's family are greater than its effects on the local migrant worker's families.
