Counting disability: emerging consensus on the Washington Group questionnaire

In November, 2016, at the fourth meeting of the Inter-agency and Expert Group on Sustainable Development Goal (SDG) Indicators in Geneva, a group of leading UN agencies, civil society actors, and independent experts issued a statement1 strongly supporting the Washington Group on Disability Statistics' Short Set of Questions (WGSS)2 as the preferred method to use with the SDGs to number the world's population of people with a disability. Further support quickly followed at the UN World Data Forum in Cape Town.
