A/70/335 record the nationality and/or ethnicity of the persons stopped. In the course of the project, evidence was found that the production of such data can reduce ethnic profiling and enhance efficiency at the same time. 16 77. The Special Rapporteur would like to emphasize that in order to complement data generated by the use of stop forms, other data sources should be used, including information gathered by civil society actors through event -based surveys documenting occurrences of racial profiling and racially motivated crimes. B. Data and the post-2015 development agenda 78. As the world is preparing to adopt a new development agenda, the question of how it has fared in implementing non-discrimination and equality measures through the Millennium Development Goals further draws attention to the need to develop adequate indicators to assess the realization of the objective of “leaving no one behind”. 79. Development indicators, such as the human development index, have demonstrated that essentially focusing on national aggregates has not enabled inequalities to be captured and has further contributed to making the most disadvantaged components of society more invisible. A World Bank study shows that about half of the 155 developing countries surveyed lack adequate data to monitor poverty and, as a result, the poorest people in those countries have often remained undetected by the existing data. 17 The same can be said at the international level, as the performance indicators developed to assess the outcome of development policies have fallen short of properly assessing the human rights aspect of development. However, the Special Rapporteur would like to acknowledge the shift in 2006 to adopting a human rights-based approach to development in the programming of the United Nations Development Programme. That approach has sought to integrate the cross-cutting human rights norms, including non-discrimination and equality, in the monitoring and assessment of development policy outcomes and the implementation of development programmes. 80. The Millennium Development Goals Report 2015, while emphasizing that significant progress has been made in reducing extreme poverty by half, als o stresses that this progress has been uneven. Millions of people are being left behind, especially the poorest and those disadvantaged because of their sex, age, disability, ethnicity or geographic location. The report identifies the lack of timely data a nd the unavailability of disaggregated data as a major challenge, which has often led to the implementation of inefficient decision-making and planning because they are based on outdated or inaccurate data. 81. Eradicating poverty and hunger remains at the core of the post-2015 development agenda and because access to basic services, such as education, health care or clean water, is frequently determined by socioeconomic status, gender, ethnicity or geography, there has been a strong call, including from ci vil society, for developing indicators that would enable the collection of more disaggregated statistics. They would capture the situation of the most vulnerable and marginalized __________________ 17 15-14106 See Umar Serajuddin and others, “Data deprivation: another deprivation to end”, Policy Research Working Paper No. 7252 (Washington, D.C., World Bank, 2015). 21/24
