View the Latest Census Estimate Data for Your State with the Redistricting and You Online Map Tool

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

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

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,…

NCSL Overview: Reallocating Incarcerated Persons for Redistricting

NCSL Overview: Reallocating Incarcerated Persons for Redistricting

In this recent article, the National Conference of State Legislatures gives an overview of the fairly recent practice of prisoner reallocation in redistricting. This process refers to counting prisoners at their home address for redistricting purposes instead of the prison's address - which is what the census does. Prisoner reallocation involves obtaining records from prison officials and careful adjustment of official census data files. This overview explains the practice and how it relates to representation. Since this article was first published, Illinois became the tenth state to mandate prisoner reallocation beginning in 2030. Feb. 18, 2021: States redistrict their legislative…

Here’s the Compressed 2021 Timeline for State Congressional Maps if Congress Passes HR1

Here’s the Compressed 2021 Timeline for State Congressional Maps if Congress Passes HR1

H.R. 1—the For the People Act—mandates significant changes to states’ congressional redistricting processes beginning with the post-2020 census redistricting in 2021. Under H.R. 1, a state’s congressional redistricting plan must be approved by a 15-member independent redistricting commission. The first six Commissioners are randomly chosen from a 36-member Selection Pool, and those six Commissioners then appoint the final nine. If a state does not form the required commission, a federal three-judge court will draw the district lines. I along with my colleague and Fellow at the New York Law School, Nicholas P. Stabile, have drafted this quick timeline for what…

Understanding the Iowa Model for Redistricting

Understanding the Iowa Model for Redistricting

The "Iowa Model" for redistricting is perhaps the least understood state procedure for redistricting. Iowa is often lauded as the nonpartisan ideal for redrawing boundaries, but in reality, nonpartisan staff draw maps that are advisory in nature and the legislature may direct staff to make changes. Ultimately the legislature can amend the map or simply draw its own. The process however is strictly nonpartisan in the sense that no political data is used in drawing maps and since the statute establishing the process was enacted in 1980, the state legislature has adopted maps drawn by staff. Below is the National…

What Will an Updated Voting Rights Act Preclearance Formula Look Like?

What Will an Updated Voting Rights Act Preclearance Formula Look Like?

The U.S. Supreme Court effectively halted administrative preclearance for redistricting maps (as well as other voting changes) for states required to do so under section 5 of the Voting Rights Act (see Shelby County v. Holder). This ended the need for the Justice Dept. to preapprove redistricting maps in TX, Georgia, Alabama, several more states, and some local jurisdictions. While the court did not actually invalidate section 5, it did declare the formula that determines which states are covered under section 5 unconstitutional because it had not been updated for some time. With Democrats in control of Congress and the…

Census Bureau Director’s Blog Post: “Anomalies” in Data are Not as Scary as they Sound

Thieme also assures readers that "we have not found any anomalies that are impossible to fix." Read the blog entry here.
