The 2012 Canadian Survey on Disability (CSD) was based on a sample of persons who reported an activity limitation on the 2011 National Household Survey (NHS) and who were 15 years of age or older as of the date of the NHS, May 10, 2011. Since the NHS excludes the institutionalized population and other collective dwellings, the CSD only covers persons living in private dwellings in Canada. Total sample size was approximately 45,500 individuals with an overall response rate of 75%.

The CSD used an instrument called the “Disability Screening Questions” (DSQ). Screener questions on the DSQ evaluate the presence and severity of 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.

It should be noted that the DSQ were specifically developed for the measurement of disability among adult Canadians (15+).

A severity score, which was developed for the survey, takes into account the number of disability types, the intensity of difficulties and the frequency of activity limitations. Using this score, persons with disabilities were classified into four severity levels: mild, moderate, severe and very severe.

The purpose of the CSD is to provide information about Canadian adults whose daily activities are limited because of a long-term condition or health-related problem. This information will be used to plan and evaluate services, programs and policies for adults with disabilities to help enable their full participation in Canadian society. Data on disability are also used to fulfill Canada's international agreement relating to the United Nations Convention on the Rights of Persons with Disabilities.
