Census 2006 - Discharge Abstract Database (DAD) Linked Data


Statistics Canada, together with The Canadian Institute for Health Information (CIHI), is conducting a pilot project to provide access to the 2006 Census linked to the Discharge Abstract Database (DAD) for 2006/07-2008/09. The pilot project will give researchers access to these linked data in a Statistics Canada Research Data Centre (RDC) and will aim to evaluate and improve confidentiality vetting rules and help to improve documentation for researchers.

The 2006 Census (long-form) was linked to the DAD for 2006/07-2008/09 to support analysis of hospital use by sub-populations and socio-economic status of Canadians. The long-form Census represents approximately 20% of the Canadian population and provides comprehensive information on demography, family, household and dwelling characteristics, geography, Aboriginal identity, activity limitations, education, ethnic origin, citizenship and immigration, income, journey to work, labour market activity, language, mobility, unpaid work and visible minorities. The DAD includes all acute-care and some psychiatric, chronic, rehabilitation and day-surgery hospital discharges in Canada (excluding Quebec) provided to Statistics Canada by CIHI.

Approximately 4.652 million long-form respondents were eligible for linkage to the DAD. The linkage was conducted using a hierarchical deterministic linkage approach. Approximately 5.3% of Census respondents were linked to at least one DAD record between 2006/07 and 2008/09. More information regarding the linkage methodology is available ( x/2015010/article/14228-eng.htm.).

The 2006 Census-DAD linked data have been used by Statistics Canada to better understand patterns of hospitalization use for key sub-populations including immigrants and Aboriginal peoples. See links for more information: and
