Distribution of Morbidity Measures by Education and Income, Population-Weighted Canadian Community Health Survey, 2000–2001, for Ontario, and Johns Hopkins Adjusted Clinical Groups, 20001–2002

		Education^a					Income^b
Morbidity Measure	Age, y	High %	Medium %	Low %	Rate Ratio	95% CI	High %	Medium %	Low %	Rate Ratio	95% CI
CCHS = Canadian Community Health Survey.
Note: Rate ratio for high/low education and income.
^a Educational attainment categorized as low (not completed high school), medium (high school completion and some postsecondary education), and high (university degree). Values missing for 0.7% of respondents.
^b Income defined using total household income adjusted for the number of people living in the household and categorized as low (Statistics Canada’s lowest and lower-middle income), medium (upper-middle income), and high (highest income). For a household with 2 or fewer people, income levels correspond with Canadian dollar incomes of <$30,000, $30,000-59,999, and ≥$60,000, respectively. Values missing for 9.0% of respondents.
