The absolute inequality reflected the degree of the difference in health between two subgroups and had the same dimensions as the health indicators. The relative inequality was the difference in the health proportion between the subgroups and was used to compare indicators with different dimensions. The variables were unordered for place of residence and gender; within the stratified indicators, both the BGV in the absolute inequality monitoring method and the T in the relative inequality monitoring method were used to assess the stratified variables based the equity of the unordered variables. Therefore, both methods were selected to measure and calculate the equity of maternal and child health outcome indicators in China. The T and BGV methods were used to consider and discuss equality in the studies of An R , Hajizadeh M , and An Q .
