The importance of data for the design, implementation, monitoring and evaluation of disability-inclusive policies is stated in both the CRPD and in the 2030 Agenda.

Article 31 of the CRPD, which addresses statistics and data collection, requires that, “States Parties undertake to collect appropriate information, including statistical and research data, to enable them to formulate and implement policies to give effect to the present Convention… The information collected in accordance with this article shall be disaggregated, as appropriate, and used to help assess the implementation of States Parties’ obligations under the present convention and to identify and address the barriers faced by persons with disabilities in exercising their rights. States Parties shall assume responsibility for the dissemination of these statistics and ensure their accessibility to persons with disabilities and others”.[1]

Moreover, paragraph 48 of Transforming our World: the 2030 Agenda for Sustainable Development states: “Indicators are being developed to assist this work. Quality, accessible, timely and reliable disaggregated data will be needed to help with the measurement of progress and to ensure that no one is left behind. Such data is key to decision-making. Data and information from existing reporting mechanisms should be used where possible. We agree to intensify our efforts to strengthen statistical capacities in developing countries...”.[2]

The SDG indicators should be disaggregated, where relevant, by income, sex, age, race, ethnicity, migratory status, disability, location or other characteristics, in accordance with the Fundamental Principles of Official Statistics (General Assembly resolution 68/261). Moreover, SDG target 17.18 aims, by 2020, to enhance capacity-building support to developing countries, including for least developed countries and small island developing States, to increase significantly the availability of high-quality, timely and reliable data disaggregated by income, sex, age, race, ethnicity, migratory status, disability, location and other characteristics relevant in national contexts.
