About this data

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

Coverage: 44 places, 280 data points, 2000–2018
Last refreshed: 21 August 2026

The Adjusted Native Parity Index (NPIA) is calculated by dividing the immigrant value for the indicator by the non-immigrant value for the indicator. If the resulting value exceeds 1, the ratio is inverted and subtracted from 2. The adjusted native parity index is symmetrical around 1 and lies in the range 0-2. An adjusted NPI equal to 1 indicates parity between immigrants and non-immigrants. In general, a value less than 1 indicates disparity in favor of non-immigrants and a value greater than 1 indicates disparity in favor of immigrants.
