A derived variable used in this analysis is income adequacy which was developed by the Health Division of Statistics Canada and used in the General Social Survey (1991) and the Canadian Health Promotion Survey (1990). Income adequacy is an indicator of socio-economic status which takes into account both household income and household size. The term adequacy refers to the fact that the amount of income that is adequate depends on the number of people to be supported. This is a more appropriate and sensitive indicator of socio-economic status than would be achieved with just household income information. The five resultant categories are not equally dispersed throughout the general population of B.C. Survey results for the province are shown below.
