^aRates for males and females standardized for age; Rates for age categories standardized by sex; standardized rates based on the 1991 Canadian population

^bPlace of residence is broken down by material deprivation for urban residents but not for rural residents. The material deprivation index is valid only within urban populations (Wilkins 2004)
