Census Bureau Releases “Demonstration” Decennial Data Products, Working with National Academies to Collect Public Input

On October 29, the Census Bureau released a set of demonstration data products that show how the privacy measures planned for 2020 Census data would have applied to data from the 2010 Census. In a blog post, Census Bureau Chief Scientist John Abowd and Associate Director for Demographic Programs Victoria Velkoff assert that the “methods we used to protect the 2010 Census and earlier statistics can no longer adequately defend against today’s privacy threats.” They describe the new disclosure avoidance techniques planned to protect 2020 Census data and invite researchers and data users to experiment with the new demonstration products and determine if they meet their needs.

To assess the adequacy of the proposed data products, the Census Bureau is sponsoring a workshop on the demonstration data products on December 11-12 conducted by the National Academies of Sciences, Engineering, and Medicine’s Committee on National Statistics (CNSTAT). CNSTAT is requesting public comments from users of decennial data products—regardless of whether the demonstration products apply to their work—to inform the agenda of the workshop and to inform the Census Bureau’s final decision making about the 2020 products. CNSTAT seeks detailed input from data users on whether the demonstration products would be adequate, how critical the data products are to their research, how comparable the new products are to the 2010 products, and how to address the tension between privacy and accuracy of 2020 Census data. Full details on information requested and how to submit comments are available on the CNSTAT website. While there is no hard deadline for comments, comments received by December 4 will be the most helpful for the workshop organizers’ planning.
