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.
