This paper proposes an empirical comparison between probabilistic record linkage and deterministic record linkage. We use both procedures for combining two diverse sources of data, an administrative archive and a sample survey, for a situation in which the true status of each pair of linked records is known. The sample survey provides information on Italian doctor prescribing behaviour in 2007; the administrative archive provides personal and professional data for the population of Italian doctors in 2007. Match rates and error rates for the two procedures are compared and discussed in order to make suggestions on when their use is appropriate. The record linkage aims at enriching the information separately stored in the two data sources.

Abstract
This paper proposes an empirical comparison between probabilistic record linkage and deterministic record linkage. We use both procedures for combining two diverse sources of data, an administrative archive and a sample survey, for a situation in which the true status of each pair of linked records is known. The sample survey provides information on Italian doctor prescribing behaviour in 2007; the administrative archive provides personal and professional data for the population of Italian doctors in 2007. Match rates and error rates for the two procedures are compared and discussed in order to make suggestions on when their use is appropriate. The record linkage aims at enriching the information separately stored in the two data sources.
