This paper explores household income per capita for the rural Yi and Manchu ethnic minority groups and the Han majority using data from the China Household Income Project 2002, 2013 and 2018. The disparity between total per capita income for the Yi and Han populations narrowed, while the average per capita income for the Manchu population remained relatively similar to that of the Han population. Decomposing total income to its sources shows that the rapid increase in agricultural income among the Yi was a main reason why the disparity in income, compared to the two other ethnic groups, narrowed. Nevertheless, reliance on agricultural income among the Yi was reduced as wage employment and migration increased. The Manchu group and the Han group also experienced rapid increases in wages and self-employment income. The aggregated value of transfers from the public sector was similar for all three ethnic groups.
