Suppression of Data

Census data obtained by CMHC are subject to Statistics Canada's suppression rules. These rules are required by law to ensure confidentiality. For more information regarding the suppression of census data used in HiCO, please consult Statistics Canada's 2006 Census Dictionary.

Statistics Canada has applied similar suppression rules to data obtained from the National Household Survey (NHS). For more information regarding the suppression of NHS data used in HiCO, please consult Statistics Canada's Data Quality and Confidentiality Standards and Guidelines (Public).

Data may not sum to totals due to suppression and random rounding applied by Statistics Canada. Where there are a large number of households, rounding has little effect on accuracy and data suppression is rare. However, small cell counts (i.e.: counts falling below 100 households) and percentages based on those counts (like the incidence of need) may suffer considerable distortion as a result of random rounding and suppression.

Likewise, some data on average household income, average shelter costs and average STIRs are suppressed by Statistics Canada to ensure confidentiality.

Comparison of Census to National Household Survey Data

Statistics Canada has cautioned that because of the methodological change from a mandatory to voluntary survey, data from the 2011 NHS may not be strictly comparable to those from earlier censuses.

The National Household Survey is not a Census. The long form of the 2006 Census consisted of a single sampling of 20% of households in Canada, with completion being mandatory. By comparison, the NHS consisted of a primary sample of 1 in 3 households and a smaller secondary sample of target household types. For all households sampled by the NHS, completion was voluntary.
