About this data

Indicator: Proportion of students at the end of lower secondary achieving at least a minimum proficiency level in mathematics, adjusted gender parity index (GPIA)
Unit: GPIA

Coverage: 50 places, 318 data points, 1995–2018

The Adjusted Gender Parity Index (GPIA) is calculated by dividing the female value for the indicator by the male value for the indicator. If the resulting value exceeds 1, the ratio is inverted and subtracted from 2. The adjusted gender parity index is symmetrical around 1 and lies in the range 0-2. An adjusted GPI equal to 1 indicates parity between females and males. In general, a value less than 1 indicates disparity in favor of males and a value greater than 1 indicates disparity in favor of females.
