CRC/C/GC/11 page 6 24. As previously stated in the Committee’s general comment No. 5 on general measures of implementation, the non-discrimination obligation requires States actively to identify individual children and groups of children the recognition and realization of whose rights may demand special measures. For example, the Committee highlights, in particular, the need for data collection to be disaggregated to enable discrimination or potential discrimination to be identified. Addressing discrimination may furthermore require changes in legislation, administration and resource allocation, as well as educational measures to change attitudes.8 25. The Committee, through its extensive review of State party reports, notes that indigenous children are among those children who require positive measures in order to eliminate conditions that cause discrimination and to ensure their enjoyment of the rights of the Convention on equal level with other children. In particular, States parties are urged to consider the application of special measures in order to ensure that indigenous children have access to culturally appropriate services in the areas of health, nutrition, education, recreation and sports, social services, housing, sanitation and juvenile justice.9 26. Among the positive measures required to be undertaken by States parties is disaggregated data collection and the development of indicators for the purposes of identifying existing and potential areas of discrimination of indigenous children. The identification of gaps and barriers to the enjoyment of the rights of indigenous children is essential in order to implement appropriate positive measures through legislation, resource allocation, policies and programmes.10 27. States parties should ensure that public information and educational measures are taken to address the discrimination of indigenous children. The obligation under article 2 in conjunction with articles 17, 29.1 (d) and 30 of the Convention requires States to develop public campaigns, dissemination material and educational curricula, both in schools and for professionals, focused on the rights of indigenous children and the elimination of discriminatory attitudes and practices, including racism. Furthermore, States parties should provide meaningful opportunities for indigenous and non-indigenous children to understand and respect different cultures, religions, and languages. 28. In their periodic reports to the Committee, States parties should identify measures and programmes undertaken to address discrimination of indigenous children in relation to the Declaration and Programme of Action adopted at the 2001 World Conference against Racism, Discrimination, Xenophobia and Related Intolerance. 11 8 CRC, general comment No. 5 on General Measures of Implementation, 2003, para. 12. 9 Recommendations of CRC Day of General Discussion on the Rights of Indigenous Children, 2003, para. 9. 10 11 Ibid., para. 6.
