Provincial Social Equality Index Dataset of China, 2000–2020

Income disparity, spatial inequality, and urban-rural inequality are three fundamental issues affecting human social equality. The Chinese government considers addressing these three inequalities as crucial for achieving common prosperity. Therefore, in response to these inequalities, the income Gini coefficient, the population-weighted CV of nighttime light, and the urban-rural income ratio were integrated to construct a social equality index (SEI). This index reflects the overall degree of social inequality in China.The specific calculation method can be found in the related paper.
