Flowchart for unweighted analytical sample (rounded by nearest 10) of Canadian Community Health Survey (CCHS) participants from 2009 to 2023. *We excluded people from the territories because of the small sample size (n = 8340 over the 15-year study period); numbers from territories cannot be reported annually and must be used only in 2-year increments. Although we recognize this is not ideal, it is a common approach for CCHS studies of trends over time. See Related Content for accessible version. Note: BMI = body mass index.
