The results described here were derived from the Health Survey. People were asked to participate in this survey on the basis of a sample survey from the Personal Records Database (BRP). Variations may exist between the respondents and the population as a whole. A correction was therefore applied by means of a weighting factor based on gender, age, migration background, marital status, geographical location, household size, income and wealth, and other factors. More information on this survey can be found in the survey description.
