IMDB-DAD (Longitudinal Immigration Database - Discharge Abstract Database)


Statistics Canada, in partnership with Immigration, Refugees and Citizenship Canada (IRCC) and the Canadian Institute for Health Information (CIHI), is pleased to announce the release of a new integrated dataset.
As part of its record data linkage activities, Statistics Canada has linked the Longitudinal Immigration Database (IMDB) with patient records in the Discharge Abstract Database (DAD). 
IRCC and CIHI are collaborating with Statistics Canada to make the integrated data available in the Research Data Centres and to support researchers using the file.
The integration of administrative immigrant data from IRCC with provincial administrative data held by CIHI creates a valuable dataset that can provide answers to important research questions that cannot be found in single administrative datasets alone. 
Statistics Canada has a long history of creating and using record linkages to integrate datasets. Record linkage is an important and cost-effective statistical technique used to develop integrated data products that can be used to address important data gaps, such as to broaden our understanding of hospital service usage patterns among immigrants.
About the Data:
A cohort of immigrants from the Longitudinal Immigration Database (IMDB) (landing years 1980 through 2013) was linked to the Discharge Abstract Database (DAD) (2000/2001 to 2013/2014).
