Federal Judge Orders Census Count to Continue Through Oct 31

By EditorSep 25, 2020
A U.S. District Judge in the Northern District of California has issued a preliminary injunction that enjoins the U.S. Census Bureau from ending its counting operations on September 30. The order explains that the coalition of plaintiffs - headed by the National Urban League - are likely to succeed in the lawsuit and that shortening the timeframes for data collection and processing by half, necessitate the preliminary injunction. The administration is expected to appeal. Read the order here. While the Census Bureau had originally requested Congress to extend the statutory deadlines for apportionment data delivery to the President and redistricting…

By EditorSep 21, 2020
On Thursday, a federal district court judge extended a temporary restraining order barring the Census Bureau from wrapping up its counting operations in order to deliver census results on its statutory time schedule. The plaintiffs in the case are asking the court to compel the Bureau to take more time to complete the nationwide count since it was delayed earlier this Spring due to Covid-19. Listen below to NPR's quick update on how and why this happened. NPR Morning Edition - Court Order Keeps Census In Limbo As Counting End Date Looms 9-17-20 In March, the Bureau had requested an…

Washington State Data Office: Privacy Protected Census Data it Sampled is “Unfit” to Use

Washington State Data Office: Privacy Protected Census Data it Sampled is “Unfit” to Use

By Michelle DavisSep 14, 2020
"The majority of the data output from the DAS [disclosure avoidance system] appears to be unfit for most uses." Is how a letter to the Census Bureau's Disclosure Avoidance Team starts off. The letter, from the Washington State Office of Financial Management, which runs the state data center, sums up the results of the state's usability test of census data treated with a disclosure avoidance technique called "differential privacy," which introduces "statistical noise" into the dataset in order to maintain the privacy of individual data. Sampling the Technique: If you are unfamiliar with the technique you can read more about…

Watch: House Committee Holds Hearing on Census Timeline

By EditorSep 13, 2020
On September 10, the House Committee on Oversight and Reform held a hearing on the status of the Census Bureau's operations in light of Covid-19 delays and other challenges. The hearing was prompted by suspension of count operations in April due to Covid-19, a failed request for Congress to extend critical statutory deadlines for delivery of census data, and an abrupt pivot by the bureau to end its count operations early in an effort to meet the original deadlines for delivery of apportionment and redistricting data. https://youtu.be/c4OF6jQFfgc Witnesses include: J.

NY Federal Court Enjoins Presidential Order to Remove Illegal Immigrants from Apportionment Count

By Michelle DavisSep 11, 2020
A federal court panel is the first to decide on whether the president's memorandum directing the U.S. Census Bureau to report the estimated number of “aliens who are not in a lawful immigration status” is unlawful. The memo's stated purpose is to subtract this estimate from the total population in each state - the number that is historically used to apportion congressional seats among the states. Read the opinion here. Officials Enjoined: The court enjoined all of the officials who were party to the lawsuit from reporting the estimate in the official apportionment report. The court did acknowledge, however, that…

What Does Differential Privacy in Census Data Mean for the Task of Redistricting?

What Does Differential Privacy in Census Data Mean for the Task of Redistricting?

By Michelle DavisSep 08, 2020
The law requires that any identifying information you give the Census Bureau be kept confidential for 75 yrs, but simply removing your information from what is published is no longer enough. Big data and powerful computing technology now allow almost anyone to "reconstruct" the seemingly anonymized information. That means it is increasingly possible to identify who you are, where you live, and other information from the census results. Here's how the Census Bureau plans to combat that. New for the 2020 census, the U.S. Census Bureau will be using a process called differential privacy to inject "statistical noise" into the…

Understanding the 2020 Census Disclosure Avoidance Policy. A.K.A. “Differential Privacy”

Understanding the 2020 Census Disclosure Avoidance Policy. A.K.A. “Differential Privacy”

By Michelle DavisSep 01, 2020
The Census Bureau is mandated by the U.S. constitution to complete a count of the population every decade. Few realize however, that Title 13, Sec. 9 of the U.S. Code also requires the Bureau to "keep personally identifiable information confidential for 72 years." With the growth of Big Data, this privacy mandate has become a much more complicated task, thanks to "database reconstruction," a method of partially reconstructing a private dataset from public aggregate information. Consider the well-known example below of how one data scientist obtained former Governor William Weld's medical history from aggregate data released to the Massachusetts Group…

Federal Court Rejects a Citizenship Question for the 2020 Census

Federal Court Rejects a Citizenship Question for the 2020 Census

By EditorJan 15, 2019
A New York federal district court has rejected the administration's bid to place a citizenship question on the upcoming 2020 census. The U.S. Department of Commerce, which is the main defendant in the lawsuit, will most likely appeal this decision but this just deepens the legal, financial and operational challenges that the Census Bureau must endure just under 15 months away from the 2020 census, the data from which, states and local governments will use to redraw electoral lines. NPR lists the possible effects that the current government shutdown and this lawsuit will have on census 2020 planning here. Read…
