Tablenote 1 Linkage Rate: The linkage rate is calculated as the percentage of owner records with accepted links to the database shown. It is the denominator for the FPR. While it is not a data quality indicator alone, in addition to the FPR and FNR it provides a complete picture of the overall linkage quality.
