16 States Join in Alabama’s Challenge to the Census Bureau’s Data Privacy Program

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)…

Oregon Supreme Court Establishes Revised Deadlines for Legislative Maps

By EditorApr 10, 2021
On Friday, the Oregon Supreme Court issued new deadlines for state legislative redistricting in light of the census redistricting data delay. The order extends state constitutional deadlines for legislative redistricting by three months. It does not address congressional redistricting in the state, which is governed by state statute. Read the opinion here. In its opinion and order, the court explained that the revised deadlines will enable the Legislative Assembly and the Secretary of State to fulfill their constitutional duties "without significantly affecting the rights of voters or interfering with the 2022 general election cycle." Practically speaking it observed that a…

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…

Reform: 2021 Gerrymandering Threat Index by Nonprofit Group “RepresentUs”

Reform: 2021 Gerrymandering Threat Index by Nonprofit Group “RepresentUs”

By EditorApr 07, 2021
RepresentUs, a nonprofit advocacy group, released an online app and 160-page Gerrymandering Threat Index report which measures each state's risk level for gerrymandering activity during the 2020 redistricting cycle. By its measure, 35 states have an extreme or high threat of gerrymandering or 70% of the nation, including over 188 million Americans. The index measures a state's likelihood that it will enact "gerrymandered" maps based on several factors including whether politicians draw maps, how transparent the process is, the robustness of legal criteria, the likelihood of partisan line-drawing, and how difficult maps are to challenge in court. Browse the risk…

By EditorApr 05, 2021
Civil rights groups are raising concerns about the accuracy of the U.S. Census Bureau’s proposed new system for protecting privacy in a report released today. The report raises concerns about how the Bureau's use of differential privacy as evidenced by recent demonstration data, will obfuscate the true population count of minority populations and frustrate compliance with federal (and some state) Voting Rights laws governing the redistricting process.

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.
