More than a billion persons globally, about 15 percent of the world’s population, are estimated to have a disability. Most of them live in low- and middle-income countries. This number is expected to increase. However, the lack of data on disability contributes to the invisibility of persons with disabilities. Including persons with disabilities and expanding equitable opportunities are at the core of the World Bank’s work to build sustainable, inclusive communities, aligned with the institution’s goals to end extreme poverty and promote shared prosperity. However, these development efforts can be hampered by poor collection of disability disaggregated data. Therefore, one of the World Bank’s 10 Commitments focuses on scaling up disability data collection and use, guided by global standards and best practices, such as using the Short Set of Questions on Disability developed by the Washington City Group on Disability Statistics. During this session, World Bank colleagues and external partners discussed recent efforts to collect better data on persons with disabilities. We also launched a new self-paced World Bank e-course “Collecting Data on Disability Inclusion” that provides technical knowledge to World Bank staff and development partners on disability disaggregated data to support inclusive development. The course includes an introduction to the Washington Group (WG) question sets.
