by Ed Christopher

This may be of interest to some: ----------------------------------------------------------------------- Yesterday the Census Bureau released the *2010 Demonstration Data Products* to help data users understand how differential privacy may or may not impact data products they are used to receiving. The products include the 2010 Demonstration Public Law 94-171 (P.L. 94-171) Redistricting Data Summary File and the Demographic and Housing Demonstration File, which is similar to Summary File 1. Documentation and resources related to these products are available on the Census Bureau’s website: https://www.census.gov/programs-surveys/decennial-census/2020-census/planni… The Census Bureau is working on an FAQ document to provide additional information about these data. You can also direct questions to the Census Bureau via email: dcmd.2010.demonstration.data.products(a)census.gov <mailto:dcmd.2010.demonstration.data.products(a)census.gov>. -- Ed Christopher Transportation Planning Consultant 708-269-5237

Because of significant changes in the data landscape, the Census Bureau is changing its approach to disclosure avoidance. The confidentiality of individuals represented “anonymously” in these statistical tables will be protected by a “formal privacy” technique that allows the Bureau to mathematically assess the risk of revealing information about individuals in the released statistical tables. The Bureau’s approach is an implementation of “differential privacy,” and it gives a rigorously demonstrated guaranteed level of privacy protection that traditional methods of disclosure avoidance do not. Given the importance of the Census Bureau’s statistical tables to democracy, resource allocation, justice, and research, confusion about what differential privacy is and how it might alter or eliminate data products has rippled through the community of its data users, namely: demographers, statisticians, and census advocates. The purpose of this primer is to provide context to the Census Bureau’s decision to use a technique based on differential privacy and to help data users and other census advocates who are struggling to understand what this mathematical tool is, why it matters, and how it will affect the Bureau’s data products.
