Is the definition of disability related to relevant programs or surveys?

You’re welcome.

Thank you.

Yes, the definition of disability is a critical issue. Even though we have the suggested guidelines as outlined by the World Health Organization, disability has been used to mean everything from a minor impairment that has little or no impact on activity to a condition that requires one to rely on others for assistance in one’s most basic functions. When it comes to surveying for disability statistics, no one accepted definition exists. National surveys or programs serving people with disabilities use specific stated definitions, but each program or survey uses definitions addressing its specific purposes. Simply put, the number of people who have a disability depends on which surveyor is asking the questions!
