About this data

Indicator: Out-of-school rate for youth of upper secondary school age, adjusted gender parity index (GPIA)
Unit: GPIA
Source: UNESCO Institute for Statistics
Licence: CC BY 4.0 (World Bank Open Data)
Coverage: 184 places, 2,951 data points, 1970–2019
Last refreshed: 04 September 2026

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.
