Canadian Survey on Disability (CSD)

Severity of disability of person with a disability, category

Severity of disability refers to a ranking based on the presence and severity of ten distinct types of disabilities related to a health problem or condition that has lasted or is expected to last for six months or more. The degree of severity increases with the frequency of the limitation and the level of difficulty. The more types of disability a person reports, the higher the global severity class.

Person with disability refers to a person whose daily activities are limited according to a prescribed level of difficulty with particular tasks due to a long-term condition or health problem lasting, or expected to last, for a specific period of time.

In the Canadian Survey on Disability, "Disability Screening Questions" (DSQ) are used to evaluate the presence and severity of ten (10) distinct types of disabilities related to a health problem or condition that has lasted or is expected to last for six months or more (the only exception to this is for developmental disabilities where a person is considered to be disabled if the respondent has been diagnosed with this condition). Screening questions emphasize consistency of measurement across disability types. The questions address the following ten (10) disability types: seeing, hearing, mobility, flexibility, dexterity, pain, learning, developmental, mental/psychological and memory. Respondents may report and therefore be classified as having more than one disability type.

The data for this variable are reported using the following classifications and/or lists:
