III. >> M  ethodological Approaches to Human Rights Indicators >> Sources and data-generating mechanisms While there are many examples of national, periodic socioeconomic surveys for collecting information that is directly relevant to assessing the realization and enjoyment of economic, social and cultural rights, few surveys focus exclusively on human rights, particularly civil and political rights. The Metagora project carried out a household Box 18 survey on indigenous peoples’ rights in the Philippines (box 18) and collected information on abuses and ill-treatment by the police in Mexico (box 19). In both instances, the participatory and multi-stakeholder approach helped the design of the surveys and to build ownership of the tools and the results. Survey of indigenous peoples’ rights in the Philippines A pilot study on the diagnosis of indigenous peoples’ rights to ancestral land in the Philippines was conducted by the Commission on Human Rights in close collaboration with the National Statistical Coordination Board, the National Statistics Office, the Statistical Research and Training Center and the National Commission on Indigenous Peoples. Using a survey-based study, the goal of the project was to measure the implementation of the Indigenous Peoples Rights Act in three northern regions of the Philippines and targeting three indigenous peoples, namely the Bago, the Bugkalot/Ilongot and the Kankanaey. The study included consultations with various leaders of the indigenous communities to identify issues that could improve the quality and usefulness of the pilot survey. This exercise showed that actors from otherwise disparate fields can inform and strengthen the work on measuring human rights. The survey revealed significant differences in the experience of violations of land rights (encroachment, pollution, illegal entry, displacement/relocation and others), ranging from 21 per cent among the Bago, to 36 per cent among the Kankanaey and 57 per cent among the Bugkalot/Ilongot. As a direct consequence of the project, the National Statistical Coordination Board reviewed the design of its national census and included questions on the demographic and social profile of indigenous peoples.
