Completion rate, primary education, female, adjusted wealth parity index (WPIA)

The Adjusted Wealth Parity Index (WPIA) is calculated by dividing the poorest quintile value for the indicator by the richest quintile value for the indicator. If the resulting value exceeds 1, the ratio is inverted and subtracted from 2. The adjusted wealth parity index is symmetrical around 1 and lies in the range 0-2. An adjusted WPI equal to 1 indicates parity between the richest and poorest quintiles. In general, a value less than 1 indicates disparity in favor of the richest quintile and a value greater than 1 indicates disparity in favor of the poorest quintile.

调整后财富均等指数（Adjusted Wealth Parity Index，WPIA）的计算方式为：以某指标的最贫困五分位组数值除以该指标的最富裕五分位组数值。若所得比值大于1，则将该比值取倒数，并以2减去该倒数。调整后财富均等指数以1为对称轴，取值范围为0至2。当调整后WPI等于1时，表明最富裕与最贫困五分位组间处于均等状态。总体而言，该指数小于1意味着资源分配差异偏向最富裕五分位组，大于1则意味着差异偏向最贫困五分位组。如需了解更多信息，请查阅联合国教科文组织统计研究所：http://uis.unesco.org/
