Percent of Canadians reported arthritis diagnosis 2003-2022

All figures are annual estimates.
Since 2007, data for the Canadian Community Health Survey (CCHS) are collected yearly instead of every two years. While a sample of approximately 130,000 respondents were interviewed during the reference periods of 2003 and 2005, it has been changed to 65,000 respondents each year starting in 2007.
Arthritis includes rheumatoid arthritis and osteoarthritis, but excludes fibromyalgia. In the 2011 French questionnaire, the word "arthrose" was added to the arthritis question as patients tend to associate the word "arthrite" with rheumatoid arthritis and "arthrose" with degenerative arthritis. However, the word "arthrose" was omitted from the question in 2012. As a result, the arthritis estimates for the province of Quebec and subsequently the Canada level were affected. The data for the arthritis indicator in 2011 should be used with caution.
Figures from 2003 to 2014 were taken from an archived page from the same source and can be accessed here.
As a result of the 2015 redesign, Canadian Community Health Survey (CCHS) has a new collection strategy, a new sample design, and has undergone major content revisions. With all these factors taken together, caution should be taken when comparing data from previous cycles to data released for the 2015 cycle onwards.
