A/70/335 monitoring whether development policies foster equal opportunities and seek to mitigate inequalities in outcome. 91. The Special Rapporteur welcomes the target of increasing the collection of disaggregated data across the prohibited grounds of discrimination under target 17.18 of the proposed sustainable development goals. He would like to stress that data should be disaggregated on the basis of the agreed -upon prohibited grounds of discrimination, rather than discretionary context relevant criteria. He invites States to inscribe the collection of ethnically disaggregated data within the framework of their obligation to fight discrimination. 92. Finally, the Special Rapporteur reminds States of the previous recommendations made by the mandate and other human rights mechanisms on the necessity of collecting disaggregated data with a view to upholding the cross-cutting human rights principle of non-discrimination. 24/24 15-14106
