This indicator is calculated based on 2 years of pooled data from 2015 and 2016.
Data for the Canadian Community Health Survey (CCHS) is collected yearly from a sample of approximately 65,000 respondents. CANSIM Table 105-0509 presents estimates from 2-year combined data and features estimates for all provinces and territories as well as for health regions. The 2-year combined data has higher precision (less variability) than annual estimates; annual CCHS estimates are not available at the health region level.
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
–Children age 12 to 17 living in foster care
–The population of institutionalized persons
–Persons living in 2 Quebec health regions: Nunavik Region and Terres-Cries-de-la-Baie-James Region
Altogether, these exclusions represent less than 3% of the Canadian population age 12 and older.
