Fwd: Census Bureau Data and Differential Privacy

by Ed Christopher

I received this today from our friends at IPUMS. Apologies if you already received this. It deals with the Differential Privacy protection that we have been hearing about. Both IPUMS has a report on it (https://assets.ipums.org/_files/mpc/MPC-Working-Paper-2018-6.pdf) and the Census Bureau's Chief Scientist (https://arxiv.org/pdf/1808.06303.pdf). I pulled the links out for the articles below in case they do come through. As users of Census Data products, this is an issue and area that we all need to understand and be cognizant of. I happen to agree with our IPUMS friends that the procedures will have a large impact on public use data products and could limit the use of microdata, but that is my opinion. -------- Forwarded Message -------- Subject: Census Bureau Data and Differential Privacy Date: Thu, 6 Dec 2018 15:04:25 +0000 From: IPUMS <ipums(a)umn.edu> Reply-To: IPUMS <ipums(a)umn.edu> To: edc(a)berwyned.com IPUMS Census and Survey Data *IPUMS Census and Survey Data * Is this email not displaying correctly? View it in your browser <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…>. IPUMS Dear IPUMS User, The Census Bureau has announced new rules for disclosure control in public use data products, including both ACS microdata and small-area data from the 2020 census. The new policies will have a large impact on public use data products, and could severely limit the utility of microdata and small-area data. I fear that scientists, planners, and the public may lose the free access we have enjoyed to reliable public Census Bureau data describing American social and economic change. Although in the immediate future this will apply only to ACS and decennial census data, the Census Bureau plans to use the same approach for other data products. In the long run, the new rules could also lead to new restrictions on access to data from other agencies. We have prepared a new report <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…> on this issue, and I urge you to read it. You may also wish to read the Census Bureau Chief Scientist's perspective on this issue, in a forthcoming article <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…>. We are in conversations with the Census Bureau about their timeline for these changes and about their plans to engage the research community. We will keep the IPUMS community informed through our social media <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…> and a dedicated webpage <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…>.

IPUMS Dear IPUMS User, 25 years ago, on a brisk Minnesota morning in early November, Steve Ruggles and the small but mighty original IPUMS team released their first dataset. The original Integrated Public Use Microdata Series included harmonized versions of the 1880, 1900, 1910, 1940, 1950, 1960, 1970, 1980, and 1990 U.S. Censuses. The first download of those data occurred on November 19, 1993. ("We didn't have a lot of traffic in those days," Steve remarked.) Since then, IPUMS has become the world's largest accessible database of census microdata, covering more than 100 countries and over 2 billion records. The team is now more than 100 people, and we've reached more than 100,000 users worldwide. . We are celebrating this milestone — but we need your assistance. If IPUMS has helped you, consider helping IPUMS. Here are a few ways you can participate. *IPUMS25* *Tell us your IPUMS story!* Do you have research that would not be possible without IPUMS data? What's your favorite variable, and why? How has IPUMS played a role in your work? We are gathering IPUMS stories and will share them on Twitter <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…> and our blog <https://nhgis.us4.list-manage.com/track/click?u=775cbf39c77535e784cdfd6f9&i…>.

PSAP Webinar recording available

by Weinberger Penelope

Hi All, Thank you for your ongoing interest in the US Census' Participant Statistical Areas Program (PSAP). Here is a link to our webinar held on October 24th: https://ctpp.transportation.org/policy-change-on-small-geography/psap-updat… CTPP PSAP Update on Small Geography Delineation Criteria and PSAP Participation Description This webinar is to discuss the 2020 Census Participant Statistical Areas Program (PSAP) block group and tract delineation criteria. CTPP data releases after the 2020 Decennial Census will no longer report by TAZ, but by block groups instead. We will give an update on the process we initiated to adapt to this change, including a discussion on how the new PSAP criteria will better enable us to align block group and TAZ boundaries to sustain the value of CTPP data for modeling and transportation planning and analysis. Learn about PSAP, how you can get involved, and who's participating in your region. This webinar will allow significant time for Q&A, so come prepared with your questions--we expect many will be curious about the same things. Program: 1. Welcome and Overview - Ben Gruswitz of CTPP Program Oversight Board and the Delaware Valley Regional Planning Commission (DVRPC) 2. PSAP Overview, Criteria, and Contact List - Josh Coutts of the US Census Bureau's Geography Division 3.

Soliciting Feedback from Users on 2020 Census Data Products, Round 2. Comment by Nov. 8

by Graham, Todd

Hi Census power users- This is one of those things that deserves repeating... Census Bureau is asking for descriptions of how you use - and why you need - specific tabulations of the 2020 Census<https://www.federalregister.gov/d/2018-15458/p-19>. This input will shape the SF1 and SF2 products that will be available 2+ years from now. They have recently re-opened the comments period. The latest Fed Register Notice<https://www.federalregister.gov/d/2018-21837> extends the comments deadline to November 8. Comments have already been submitted by State Data Center agencies from Alaska, Arizona, California, Colorado, Mass., Michigan, Nevada, North Carolina, and Wisconsin. You can see everyone's comments here<https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0…>. It's public info! Why your comments matter: Differential privacy protection. The Census Bureau will modify some Decennial SF1 and SF2 tabulations that were previously available - and they could reduce the details available for census blocks (the most detailed, localized geographic level). Unpacking what I've heard about this, I believe the Census Bureau is considering a range of possibilities. They are really asking: * What tables or variables are mandatory and must be precise to the nearest 1 person? * What tables or variables can allow for "perturbing" or "noise infusing" of data cells - typically through block-to-block swapping of individual microdata records - in order to protect privacy? * And what tables that were previously published for census blocks can be "clawed back" - and be tabulated only for larger geographic units. Some background information on differential privacy protection can be found in recent presentations by Census Bureau<https://www2.census.gov/cac/sac/meetings/2018-09/abowd-disclosure-avoidance…>. Give it some thought - and get those comments in.
