A/69/267 housing censuses, examples of which are noted throughout the specific country reports of the previous Special Rapporteurs. This information has been and will be invaluable as a basic requirement for monitoring the impact of the upcoming sustainable development goals. 50. However, one limitation of the disaggregation of data collected against common socioeconomic indicators is that such data may essentially serve to monitor discrimination against indigenous individuals in terms of their access to and achievement of social and economic rights while pr oviding little information on the range of attributes of these rights pertaining to the right to self -determination. For example, disaggregated data may show a gap in educational outcomes, but will not supply information as to whether the education provide d was culturally appropriate, or whether the student was able to learn in his or her own language, for example. Likewise, a simple registration of increased income may be read as indicating positive progress, even in situations where indigenous peoples hav e been forced to leave a more subsistence-oriented economy. 51. At the most basic level, the indicators should assist with the detection of discrimination, inequality and exclusion, and should allow for comparisons to be made between indigenous peoples and other population groups. Furthermore, there is a need for specific indicators that capture essential aspects of self -determined development, such as status and trends in the development and use of indigenous languages, security of tenure with regard to lands, territories and resources and the recognition of indigenous customary law and autonomous governance institutions. Above all, it is essential that indigenous peoples participate in defining the issues to be addressed and the indicators used, and that indigenous peoples’ own views on well-being and their visions for the future are taken into account. 52. The Special Rapporteur will continue her work on practical approaches to assessing progress in the realization of indigenous peoples’ rights, and she looks forward to collaborating with Governments, indigenous peoples, United Nations agencies and other interested parties in identifying good practices within this field, which should be reflected in the framework to monitor the forthcoming sustainable development goals. Marginalization of indigenous peoples in developed countries 53. National statistics in middle- and high-income countries may also hide the persistent social and economic marginalization of indigenous peoples. The previous Special Rapporteurs have highlighted this situation in their reports, for example, on the situation of indigenous peoples in Australia (A/HRC/15/37/Add.4), New Zealand (A/HRC/18/35/Add.4), the United States of America (A/HRC/21/47/Add.1) and Canada (A/HRC/27/52/Add.2). This concern has also been repeatedly raised by the Permanent Forum on Indigenous Issues. For example in the context of discussions related to the Millennium Development Goals, the Forum pointed out that indigenous peoples in developed countries “suffered from significant disparities in the enjoyment of economic, social and cultural rights. Such disparities tended to be masked at the international level owing to the lack of disaggregated data and the high level of enjoyment of such rights by the non-indigenous population compared with indigenous peoples”. 15 __________________ 15 14/23 E/2006/43-E/C.19/2006/11, para. 6. 14-58847
