V. >> F ramework in Practice - Implementing and Monitoring Rights >> Interpreting statistical information from a human rights perspective Figures XVIII and XIX provide two additional illustrations of the levels of disaggregation and data analysis that may be considered for school enrolment in assessing the realization of the right to education and the right to non-discrimination and equality. Moreover, unlike the literacy rate (outcome indicator), the indicator on school enrolment Fig. XVIII (process indicator) would have the advantage of capturing the shorter-term impact of policy measures for improving literacy levels (through higher enrolment) or implementing the plan of action for compulsory primary education (structural indicator).21 Disaggregation of data for equality and discrimination analysis Enrolment ratio for girls Enrolment ratio for boys Disaggregation by sex Enrolment ratio by income quintile Disaggregation by income/type of school Enrolment ratio by province SCHOOL ENROLMENT RATIO Enrolment ratio by public/private school Disaggregation by geography Enrolment ratio by rural/urban area Disaggregation by other target groups Enrolment ratio for children of linguistic minorities, migrant families, with disabilities, etc. Enrolment ratio by ethnic, religious, age group, etc. 21. Statistics on literacy are usually compiled through census or survey data, i.e., costly methods implemented only every 5 or 10 years. Enrolment statistics are based on administrative records usually maintained by a ministry of education and disseminated annually. Human Rights Indicators 129
