In this chapter, we present an overview of the uses of proxy variables when combining data from multiple sources. In the remaining of this introductory section, we will explain what we mean by register and survey data, how the multisource data perspective differs from the survey-data centric view, and the concept of proxy variables in the context of multisource data. In Section 1.2, we consider the many and various instances of proxy variable, based on a systematic examination of the processing steps of data integration and associated error sources. In Section 1.3, we classify and outline estimation methods in the presence of multiple proxy variables. It is seen that the traditional role of auxiliary data from administrative sources can be greatly extended under the multisource data perspective. A short summary and discussion of future research is given in Section 1.4.
