This dataset belongs to the National Household Survey (NHS) 2011 profile that presents information from the 2011 NHS survey for various levels of geography, including provinces and territories, census metropolitan areas/census agglomerations, census divisions, census subdivisions, census tracts, federal electoral districts and health regions.
In order to provide a comprehensive overview of an area, this product presents data from both the NHS and the 2011 Census. NHS data topics include immigration and ethno-cultural diversity; aboriginal peoples; education and labor; mobility and migration; language of work; income and housing. 2011 Census data topics include population and dwelling counts; age and sex; families, households and marital status; structural type of dwelling and collectives; and language.
The data are collected for private dwellings occupied by usual residents. A private dwelling is a dwelling in which a person or a group of persons permanently reside. Information for the National Household Survey does not include information for collective dwellings. Collective dwellings are dwellings used for commercial, institutional or communal purposes, such as a hotel, a hospital or a work camp.
To ensure confidentiality, the values, including totals are randomly rounded either up or down to a multiple of 5 or 10. As a result, when these data are summed or grouped, the total value may not match the individual values since totals and sub-totals are independently rounded.
In addition to random rounding, area and data suppression have been adopted to further protect the confidentiality of individual respondents’ personal information.
Area and data suppression results in the deletion of all information for geographic areas with populations below a specified size. For example, areas with a population of fewer than 40 persons are suppressed. In addition to area suppression, information is suppressed if the global non-response rate to the National Household Survey was greater than 50% or greater than 25% for the Census of Population. Any income data collected from the National Household Survey are suppressed if the population in the area is less than 250 or if the number of private households is less than 40. Suppression of data can also be due to poor data quality or to other technical reasons.
The Constitution of Canada requires that the number of seats in the House of Commons is recalculated and the boundaries of federal electoral districts (FEDs) be reviewed after each 10-year census to reflect changes and movements in Canada’s population. This process is known as the redistribution of federal electoral districts. A 2013 Representation Order was proclaimed with 338 federal electoral districts and reported in the Canada Gazette on October 5, 2013.
Many of the 338 federal electoral districts (2013 Representation Order) do not fully align with the 2011 Census geographic structure. To tabulate the data from the 2011 National Household Survey, the 2011 dissemination block structure was used. In some cases, dissemination blocks were split between FEDs and had to be assigned to a single FED for the purpose of tabulating the data. For this reason, and also due to random rounding and weighting, the 2011 National Household Survey data for these FEDs may not match the population counts reported in the Canada Gazette. In addition, the 2011 National Household Survey is based on the population in private households rather than the total population.
