Abstract

Statistical Agencies manage huge amounts of microdata. The main task of these agencies is to provide a variety of users with general information about for instance the population and the economy. However, in some cases users request additional, more specific information. Many agencies have therefore set up facilities that enable selected users to obtain tailor-made statistical information.A remote access system is an example of such a facility where users can submit queries for statistical information from their own computer. These queries are handled by the statistical agency and the generated, possibly confidentialised, output is returned to the user. This way the agency still keeps control over its own data while the user does not need to make frequent visits to the agency.For some years, the Luxembourg Income Study (LIS) and Luxembourg Employment Study (LES) have made use of an advanced remote access system. At Statistics Netherlands and at other statistical institutes recently the need for a similar system has been expressed. In this article, we discuss the characteristics, limitations and desired properties of a remote access system. We illustrate the discussion by the system used at LIS/LES.
