This dataset belongs to a National Household Survey (NHS) 2011 profile that presents information from the 2011 National Household Survey (NHS) 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.
The primary use of the data at the Health Region level is for health surveillance and population health research. Federal and provincial departments of health and human resources, social service agencies, and other types of government agencies use the information to monitor, plan, implement and evaluate programs to improve the health of Canadians and the efficiency of health services. Researchers from various fields use the information to conduct research to improve health. Non-profit health organizations and the media use the health region data to raise awareness about health, an issue of concern to all Canadians.
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 ethnocultural 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.
