About this data

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

Coverage: 39 places, 219 data points, 1995–2018
Last refreshed: 21 August 2026

The Adjusted Location Parity Index (LPIA) is calculated by dividing the rural value for the indicator by the urban value for the indicator. If the resulting value exceeds 1, the ratio is inverted and subtracted from 2. The adjusted location parity index is symmetrical around 1 and lies in the range 0-2. An adjusted LPI equal to 1 indicates parity between rural and urban locations. In general, a value less than 1 indicates disparity in favor of urban locations and a value greater than 1 indicates disparity in favor of rural locations.
