“Synthetic Longitudinal Business Databases for International Comparisons” — Joerg Drechsler, Institute for Employment Research ; Lars Vilhuber, Cornell University
International comparison studies on economic activity are often hampered by the fact that access to business microdata is very limited on an international level. A recently launched project tries to overcome these limitations by improving access to Business Censuses from multiple countries based on synthetic data. Starting from the synthetic version of the longitudinally edited version of the U.S. Business Register (the Longitudinal Business Database, LBD), the idea is to create similar data products in other countries by applying the synthesis methodology developed for the LBD to generate synthetic replicates that could be distributed without confidentiality concerns. In this paper we present some first results of this project based on German business data collected at the Institute for Employment Research.
“Usage and outcomes of the Synthetic Data Server,” Lars Vilhuber (NCRN, Cornell University) and John Abowd (NCRN, Cornell University)
The Synthetic Data Server (SDS) at Cornell University was set up to provide early access to new synthetic data products by the U.S. Census Bureau. These datasets are made available to interested researchers in a controlled environment, prior to a more generalized release. Over the past 5 years, 4 synthetic datasets were made available on the server, and over 100 users have accessed the server over that time period. This paper reports on interim outcomes of the activity: results of validation requests from a user perspective, functioning of the feedback loop due to validation and user input, and the role of the SDS as a access gateway to and educational tool for other mechanisms of accessing detailed person, household, establishment, and firm statistics.
Lars Vilhuber speaks about “Disclosure Limitation and Confidentiality Protection in Linked Data” at the Center for Interuniversity Research and Analysis of Organizations‘s conference on “Facilitate the access to Quebec data: How and to what ends?” The conference is jointly organized with the Quebec inter-University Centre for Social Statistics (QICSS). The presentation relies on joint work with John M. Abowd and Ian M. Schmutte.
