Interpretation for Figure DIn Ontario, the proportion of cannabis users increases as income increases. Notes on the income groupingThe income variable was based on a derived income variable from the CCHS. This variable provided a distribution of respondents in deciles based on the adjusted ratio of their total household income to the low income cut-off corresponding to their household and community size. It provides, for each respondent, a relative measure of their household income to the household incomes of all other respondents. The income variables used in this report were determined as follows: the lowest 3 deciles of the derived variable from CCHS were categorized into 'Lower Income', the middle 4 deciles were categorized into 'Middle Income' and the highest 3 deciles were categorized into 'Higher Income'. |

Confidence intervals explained |
||||||||||||||||||||||||||||||||||||||||
Researchers look at the "confidence levels" of percentages being compared to decide if there is a statistically significant difference between percentages. A statistically significant difference means that:
In this report, 95% confidence intervals will accompany each percentage in all figures and tables. This interval represents the range in which we are 95% confident the true percentage will fall within. In tables, the 95% confidence intervals will be written with the percentage, followed by the 95% confidence interval range in brackets (e.g., 25% (12.3, 32.4)). In figures, the 95% confidence interval is represented by vertical bars in each bar line. |
