The recently established Social Data Linkage Environment (SDLE) provided a novel and effective tool to conduct a mother-centric linkage, leveraging the Derived Record Depository (DRD) that stored a collection of personal identifiers from tax records, vital statistics registration records (births and deaths), and immigration data and so forth. Through internal linkage in the SDLE, a cohort of mothers (Mothers File) was created using information from the Canadian Vital Statistics Birth Database (CVSB) and the Canadian Vital Statistics Stillbirth Database (CVSS). The Mothers File was then linked to data from the immigration, hospitalization. This integration added rich immigration and health services utilization information to the Mothers File such as immigration status, education at admission, income for immigrants, and hospital admission and discharge, etc. This data integration also provided the first comprehensive longitudinal database of Mothers and Infants in Canada, which significantly expands the analytical capacity.
