"A microdata file is the set of answers obtained by survey path. For household surveys or population censuses, files of this type are hierarchical if the data on all the persons in the households sampled or enumerated are present. The statistical agencies ensure that this data remain anonymous by eliminating all possibility of identification. A number of countries produce hierarchical files of microdata from their censuses. Canada, however, does not. As a matter of fact, Canada has disseminated microdata files since 1971 but these files have always been designed without incorporating the complete hierarchy of households. We are assessing here the protection of statistical confidentiality for the 2001 census, that is, we are assessing whether it is easy or very difficult to identify individuals from data alone. We define two measurements of statistical confidentiality protection: the conditional probability of uniqueness and the conditional probability of exact matches. We apply these two measurements to a set of records from the 1996 census for various groups of variables. On the basis of the results obtained, we conclude that publication of a public use hierarchical file significantly reduces the protection of statistical confidentiality"--Abstract, p. iii.

These guidelines have been prepared a Task Force set up by the Conference of European Statisticians, with two main objectives.- The first is to foster greater uniformity of approach by countries to allow better access to microdata for the research community. The second is to produce guidelines and supporting case studies, which will help countries improve their arrangements for providing access to microdata.

Improving Access to and Confidentiality of Research Data summarizes a workshop convened by the Committee on National Statistics (CNSTAT) to promote discussion about methods for advancing the often conflicting goals of exploiting the research potential of microdata and maintaining acceptable levels of confidentiality. This report outlines essential themes of the access versus confidentiality debate that emerged during the workshop. Among these themes are the tradeoffs and tensions between the needs of researchers and other data users on the one hand and confidentiality requirements on the other; the relative advantages and costs of data perturbation techniques (applied to facilitate public release) versus restricted access as tools for improving security; and the need to quantify disclosure risksâ€"both absolute and relativeâ€"created by researchers and research data, as well as by other data users and other types of data.
