Data linkage
What is data linkage?
Linkage allows information on an individual from one data source to be linked to information on the same individual from another data source. Using the linked data makes it possible to gain a more comprehensive understanding than could be obtained from either data source individually.
Linkage can also be used for conducting longitudinal analyses within the same data source, even when identifying information is recorded inconsistently, incompletely or has changed over time.
Data access has been approved for a study examining the impact of environmental exposures on early childhood development.
