Washington Group on Disability Statistics

The Washington Group on Disability Statistics (WG) is a UN city group established under the United Nations Statistical Commission. The WG was constituted to address the urgent need for cross-nationally comparable population based measures of disability. Its mandate is the promotion and co-ordination of international co-operation in the area of health statistics focusing on disability data collection tools suitable for censuses and national surveys.

The WG has sought to foster international collaboration, and in particular, to insure that its efforts are broad-based and inclusive of voices from developing countries from every region of the world. Representatives of National Statistical Offices around the world, as well as Disabled People’s Organizations (DPO), and other international organizations are encouraged to participate in the WG.

With funding from the Australian Department of Foreign Affairs and Trade the Washington Group on Disability Statistics (WG) is launching this new website, with the support of the Leonard Cheshire Disability and Inclusive Development Centre at University College London.

A new blog post from Washington Group member Dr. Daniel Mont is now available, “Does the WG-SS identify all people with disabilities, and does it matter?

The 17th meeting of the Washington Group is confirmed to take place at the International Convention Centre in Sydney, Australia on the 30 October – 2 November 2017. The hosts will be the Australian Bureau of Statistics.

National Statistics Offices from the ESCWA region met in Morocco in April 2017 for a technical training on implementing the WG in their upcoming censuses

The Washington Group presented their first training for Non-Government Organisations in London (March 16 2017)

The Washington Group was represented at the first UN World Data Forum in January 2017

The 16th Annual Meeting was held in Pretoria, South Africa in December 2016

The most recent meeting of the Inter-agency Expert Group on Sustainable Development Goal Indicators  (November 2016) key international agencies working on disability and DPOs, released a document stating their recommendation that the Washington Group tool sets be used for Sustainable Development Goal data disaggregation.

Over the past 15 years the WG has developed and tested several tools to be used for the collection of internationally comparable disability statistics.  Products developed by the WG include a Short Set of Six Questions on functioning designed primarily for censuses; Extended Set of Questions on Functioning for surveys; and, in collaboration with The United Nations Children’s Emergency Fund (UNICEF), a survey module on Child Functioning. While the latter is still in the testing phase of development, the Short and Extended sets have been fully tested and adopted.

The Short Set of Questions has been recommended by the United Nations and the Council of European Statisticians as the means to collect information on disability in the upcoming 2020 round of censuses. Furthermore, this set of questions has been endorsed by an Expert Group under the auspices of United Nations Department of Economic and Social Affairs (UNDESA) as the means to disaggregate by disability status for evaluating the Sustainable Development Goals.

The Washington Group is currently funded by a grant from the Australian Department of Foreign Affairs and Trade. The Secretariat is based at United States National Center for Health Statistics. The WG also has a close working partnership the Leonard Cheshire Disability and Inclusive Development Centre at University College London.

Priorities of the Washington Group

  1. Promote and coordinate international cooperation in the area of health statistics by focusing on disability measures suitable for censuses and national surveys.
  2. Provide basic necessary information on disability which is comparable throughout the world.
  3. Recommend one or more extended sets of survey items to measure disability to be used as components of population surveys or as supplements to speciality surveys.
  4. Disseminates WG materials through the world-wide web and scientific publications to foster inclusion of disability in international development and global health efforts.
