Data Integration and Record Matching: An Austrian Contribution to Research in Official Statistics
Data integration techniques are one of the core elements of
DIECOFIS, an EU-funded international research project that aims at
developing a methodology for the construction of a system of indicators on
competitiveness and fiscal impact on enterprise performance. Data
integration is also of major interest for official statistics agencies as a means
of using available information more efficiently and improving the quality of
the agency's products. The Austrian member of the project consortium
comprises university departments, representatives from the Bundesanstalt
Statistik Austria, from the Statistical Department of the Austrian Economic
Chamber, and from ec3, a non-profit research corporation. This paper gives
a short report on DIECOFIS in general and on the Austrian contribution to
the project, mainly dealing with data integration methodology. Various
papers that have been read at the DIECOFIS workshop last November in
Vienna, will be published as a Special Issue of the Austrian Journal of
Statistics
Data Integration: Techniques and Evaluation
Within the DIECOFIS framework, ec3, the Division of Business
Statistics from the Vienna University of Economics and Business
Administration and ISTAT worked together to find methods to create a
comprehensive database of enterprise data required for taxation microsimulations
via integration of existing disparate enterprise data sources. This
paper provides an overview of the broad spectrum of investigated
methodology (including exact and statistical matching as well as
imputation) and related statistical quality indicators, and emphasises the
relevance of data integration, especially for official statistics, as a means of
using available information more efficiently and improving the quality of a
statistical agency's products. Finally, an outlook on an empirical study
comparing different exact matching procedures in the maintenance of
Statistics Austria's Business Register is presented
