Note: Confidentiality disclosure control for the National Household Survey (NHS)
Disclosure control rules have been applied to data tables available from the National Household Survey (NHS). The number of actual records used to derive any number in a table must meet a minimum criterion. For a table cell where this criterion is not met, the number is replaced by a zero. Due to this disclosure control, subtotals will not necessarily aggregate to the total. As well, users should note that random rounding has also been applied to the data.
Note: Differences between the 2011 National Household Survey (NHS) estimates and census counts
The 2011 Census of Population and the 2011 National Household Survey (NHS) both provide information on the Canadian population for various levels of geography and for numerous common topics (e.g., demography, marital status, family and language) including characteristics associated to these topics. It is possible that differences exist between the 2011 Census count and the NHS estimate. Two reasons can explain these differences:
- The definition of the population of each data source: the target population for the 2011 Census includes usual residents in collective dwellings and persons living abroad, whereas the target population for the NHS excludes them.
- The variability of the estimates for the NHS: the NHS estimates are derived from a sample survey and are therefore subject to sampling error; they are also subject to potentially higher non-response error than in the census due to the survey's voluntary nature.
Note: The 2011 National Household Survey (NHS) estimates - quality indicators
For the 2011 National Household Survey (NHS) estimates, the global non-response rate (GNR) is used as an indicator of data quality. This indicator combines complete non-response (household) and partial non-response (question) into a single rate. The value of the GNR is presented to users. A smaller GNR indicates a lower risk of non-response bias and as a result, lower risk of inaccuracy. The threshold used for estimates' suppression is a GNR of 50% or more.
