Data Linkage

Data linkage is the process of connecting data from different sources that refer to the same entity or event. This process involves identifying and matching records that relate to the same individual, household, or business across different datasets. Data linkage is a crucial step in data integration and is used in various fields, including healthcare, social sciences, and business. In healthcare, data linkage is used to combine information from different sources, such as hospital records, health surveys, and administrative data, to create a comprehensive picture of a patient's health status. In social sciences, data linkage is used to combine data from surveys, administrative records, and other sources to study social and economic trends. In business, data linkage is used to combine customer data from different sources to create a unified view of customer behavior and preferences.
