About this data

Indicator: Proportion of students at the end of lower secondary education achieving at least a minimum proficiency level in reading, adjusted wealth parity index (WPIA)
Unit: WPIA

Coverage: 46 places, 295 data points, 2000–2018

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.
