Record Linkage Study

**Semantic type:** Research Activity

**Definition:** A study in which data from different sources are "linked". Usually used to compile epidemiological data. The logic of record linkage is that two or more items of information about a person recorded at different times, and perhaps in different places, may be of greater value when considered together than when either is considered alone.
