The Gender Parity Index (GPI) reflects females' level of access to education compared to that of males. This is calculated for each school phase. A GPI of less than 1 indicates that there are fewer females than males in the formal education system in proportion to the appropriate school-age population. A GPI of more than 1 means that there are proportionately more girls than boys attending school. A score of 1 reflects equal enrolment rates for boys and girls.
