Results are reported using 2013 health region boundaries.
Some values have data quality flags that indicate "use with caution" or "suppressed" due to high coefficients of variation: health regions with small populations and results disaggregated by age group or sex within small regions.
The two-year combined data is less current than annual estimates but has higher precision (less variability). Users should refer to the annual CANSIM Table 105-0501 as the primary source for the most current estimates from the CCHS as well as to obtain data from previous years. However, where data quality flags indicate suppression (F) or higher variability (E), the two-year CANSIM Table 105-0502 should be used. Self-reported data is subject to bias.
The CCHS covers the population age 12 and older living in the 10 provinces and 3 territories. Excluded from the survey's coverage are the following:
–Persons living on reserves and other Aboriginal settlements in the provinces
–Full-time members of the Canadian Forces
–The population of institutionalized persons
–Persons living in two Quebec health regions: Nunavik Health Region and Terres-Cries-de-la-Baie-James Health Region
Altogether, these exclusions represent less than 3% of the target population.
In the north, the frame for the CCHS covers 92% of the target population in Yukon, 96% in the Northwest Territories and 92% in Nunavut. Before 2013, coverage in Nunavut was 71%.
