Census Bureau Announces Revised Data Release Schedule But Stops Short on Firm Date for Redistricting Data

By EditorJan 28, 2021
The target date for apportionment data is April 30 2021. Bureau officials say a date for the release of redistricting data for the states is forthcoming, but they are certain that date will not be before July 30. A Census Bureau official made these detailed remarks on Wed, Jan. 27 to a group of legislators and staff on a conference/video call organized by the National Conference of State Legislatures. In the past, processing and preparation of apportionment and redistricting data was accomplished in a parallel process. This decade, the Bureau made the decision to focus entirely on producing the apportionment…

Listen: Supreme Court Oral Argument in Trump Apportionment / Citizenship Case

By EditorDec 01, 2020
On Monday the U.S. Supreme Court heard oral argument in Trump v. New York. This case challenged an executive memo directing the Census Bureau to report official congressional apportionment data so that it excludes the count of non-citizens. For an in-depth analysis of the arguments, read SCOTUSBlog.com's report. Most expert observers say the court seemed preoccupied with the "ripeness" of the issue, or in layman's parlance - whether or not the administration has done anything yet that could possibly violate a statute or the constitution.

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…
