Trend of disability prevalence in Iran: An evidence to improve disability data

Accurate, comparable, and accessible health care data play an important role in the planning, policy making, development and maintenance of health care services.[10,11] Internationally, methodologies for collecting data on people with disabilities need to be developed, tested cross-culturally and applied consistently. Data need to be standardized and internationally comparable to benchmark and monitor progress on disability policies and on the implementation of the Commi ee on the Rights of Persons with Disabilities nationally and internationally.[12] Considerable, collaborative, and responsibly eff orts must be done in Iran to improve disability data. We not only need information about number of disability in Iran but also need information about their needs and required services.
