Disability data collection: a summary review of the use of the Washington Group Questions by development and humanitarian actors

This report examines the use of the Washington Group Questions, a disability data collection methodology originally designed for use in national data efforts, amongst development and humanitarian actors.

The Washington Group Questions on Disability are rapidly emerging as the preferred data collection methodology by national statistical offices for national data collection efforts on disability. In addition, more and more development and humanitarian actors are now using the methodology in their own data collection efforts.

Results show that when used correctly, the WG short set questions (WG-SS) can identify the number of persons with disabilities reached by a service or programme. In addition, more often than not, the use of the WG questions by humanitarian and development organisations resulted in positive culture changes towards inclusion of persons with disabilities.
