Abstract

This paper constructs a multidimensional Theil Index to estimate and decompose the inequality of nutrition intake among the adult population in China. Using 1991–2009 China Health and Nutrition Surveys (CHNS), this paper features two major findings. First, we show that the nutrition inequality has remained small in contrast to the large and increasing inequality in population income. Second, using Theil decompositions and Oaxaca–Blinder (O-B) decompositions, we find that, unlike income inequality, nature factors (such as age and gender) and regional factors play a more important role than socioeconomic factors in nutrition inequality. This finding provides a plausible explanation to the different time trends of nutrition inequality and income inequality. Moreover, it suggests that policies that aim to reduce the socioeconomic disparities may not automatically transfer to closing the gap in nutrition intake, which in turn is a potentially important determinant of population health and the long-term economic development.
