By EditorApr 14, 2021
On Monday, 16 states joined Alabama in deriding the U.S. Census Bureau's newly adapted data privacy policy (aka differential privacy) which uses statistical algorithms to distort raw census data before it is released to states and the public. The states who jointly filed as amici in Alabama's lawsuit against the Bureau are Alaska, Arkansas, Florida, Kentucky, Louisiana, Maine, Mississippi, Montana, Nebraska, New Mexico, Ohio, Oklahoma, South Carolina, Texas, West Virginia, and Utah. The amicus brief filed on behalf of these states lists three "major harms" caused by differential privacy. 1) local redistricting cannot be conducted with any reasonable accuracy; 2)…

U.S. Census Bureau Releases Bulletin to Allay Fears and Explain its Testing Strategy for Differential Privacy

U.S. Census Bureau Releases Bulletin to Allay Fears and Explain its Testing Strategy for Differential Privacy

By EditorApr 07, 2021
This week, the U.S. Census Bureau released a bulletin that sounds a lot like it is a response to a report released by MALDEF and other civil rights groups earlier in the week. That report warns that the Bureau's application of differential privacy (DP) statistical techniques that alter census redistricting data to protect privacy, is likely to frustrate implementation of the Voting Rights Act during the redistricting process, ultimately disenfranchising minority voters. In particular, the MALDEF report claims that recent samples of 2010 census data treated with various degrees of differential privacy (DP) techniques will obfuscate the true population count…

The Center for Urban Research (CUR) at The Graduate Center of the City University of New York (CUNY) has created the Redistricting & You online map to help members of the public, journalists, elected officials, and other redistricting stakeholders to understand the local implications of redrawing legislative district lines across the country. The website uses the latest population estimates from the U.S. Census Bureau to show several population characteristics that will help inform the redistricting debate. Until census 2020 data is available, the most current data to show how congressional and state legislative district demographics have changed is from the American Community Survey, either from the 5-year 2015-2019 estimates or…

Study: Census Bureau’s Differential Privacy Disclosure Avoidance System Produces Concerning Results for Local Jurisdictions

By EditorMar 31, 2021
Recent research into the effect of differential privacy (DP) on Alaska's census data show concerning results, especially for small area geographies such as townships, municipalities and other local jurisdictions. The authors of the study, a summary of which is posted in the blog for the Population Association of America, warn that local redistricting and other activities connected to census data could be substantially impacted by the Census Bureau's application of differential privacy on raw census data. The authors of the study, David Swanson, Professor Emeritus, Sociology at the University of California - Riverside, T.M. Bryan of Bryan Demographic Research, Richmond,…
