Data Notes

  1. Data Source: Canadian Community Health Survey, [2007,2008,2009,2010,2011,2012], Share File, Ontario Ministry of Health and Long Term Care.
  2. The Canadian Community Health Survey (CCHS) collects data through participant self-report. Data collected through self-report can be biased due to inaccurate memory or because of social desirability. Social desirability happens when individuals answer questions in a manner that they think will be viewed favourably, and is more likely to occur when individuals are answering sensitive questions.
  3. Values are for those aged 12 and over.
  4. Not Stated and Don’t Know responses were excluded from analysis.
  5. 95% CI = 95% confidence interval. The 95% confidence interval provides a range within which we are 95% confident that the true population proportion (%) falls. If a stated result percentage is 18% with a 95% CI of 15.0-21.0%, we can be 95% confident that the true percentage lies within the range of 15.0% to 21.0%. The wider the confidence interval, the more variability there is, and the less precise the estimate.
  6. Significant differences were determined based on non-overlapping confidence intervals.
  7. Understanding income quintiles used in this report: The Canadian Community Health Survey contains a variable that groups Windsor-Essex survey respondents into one of 10 income deciles. Each decile contains 10% of the sample population. So that the lowest or first decile contains the 10% of the population that has the lowest household income, and the highest or 10th decile contains the 10% of the sample population that has the highest household income. The calculation takes into account reported household income, low-income cut-off values, household size, and community size. For the purposes of this report, deciles were used to create quintiles for ease of analysis and interpretation (quintiles are fifths, and so each quintile contains 20% of the sample population). The lowest two deciles were combined to make the lowest quintile, the third and fourth deciles were combined to create the second lowest quintile, and so forth, with the two highest income deciles being combined to make the highest income quintile.
  8. A white ethnic background was defined as an individual who reported that their ethnicity was white. All other ethnicities were coded as minority.
  9. Immigrant was defined as someone who had ever immigrated to Canada.
  10. The geographical area of Windsor-Essex County represents the population of the entire county of Essex and includes all municipalities within the county.
  11. Age standardized statistics available upon request.
