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.    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.

4.    Due to the large 95% confidence intervals for some values, please interpret estimates with caution. 

5.    Not applicable, Not Stated, and Don’t Know responses were excluded from all analyses, excluding those presented in Table 1.
