Regional-level results for Nova Scotia are not available. In 2014, the Health Authorities Act passed by the Nova Scotia legislature consolidated the 10 district health authorities into 2 (1 provincial health authority with 4 management zones, and the IWK Health Centre). Canadian Community Health Survey (CCHS) data was not available for the new health authority boundaries.
The data year reflects the CCHS survey cycle. Prior to 2007, data for the CCHS was collected every 2 years, involving a sample of 130,000 respondents. In 2007, the survey transitioned to a yearly collection cycle, involving a sample of 65,000 respondents.
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 2-year combined data has higher precision (less variability) than annual estimates. Users should refer to the annual CANSIM Table 105-0501 as the source for 2014 yearly CCHS estimates, as well as to obtain data from previous years. However, where data quality flags indicate suppression (F) or higher variability (E), the 2-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 2 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%.
