Differential Privacy for 2020 U.S. Census (I)

HDSR 2019 Conference Opening Remarks

Chair: John Eltinge (U.S. Census Bureau)

After a background introduction by the Census Bureau, three research teams present their findings from comparing analyses of 1940 Census files with and without the differential privacy protection protocol planned for the 2020 Census. (Speakers are indicated by *.)

Introduction and Overview

John Eltinge

Background on Differential Privacy at the U.S. Census Bureau and 1940 Census Application

Michael B. Hawes* and Philip Leclerc* (U.S. Census Bureau)

The Effect of Differentially Private Noise Injection on Sampling Efficiency and Funding Allocations: Evidence from the 1940 Census

Redistricting in 2020

HDSR 2019 Conference Redistricting in 2020

Chair and Moderator: Moon Duchin (Tufts University)

The science of elections is very much in the news, from high-stakes redistricting lawsuits to reform initiatives creating independent redistricting commissions, to the adoption of alternative voting systems like ranked-choice voting. This session features four mathematicians (with backgrounds in applied analysis, probability, combinatorics, and geometry) working on the edge of theory and data to improve how we think about and practice redistricting.

Partisan gerrymandering versus geographic compactness
Dustin Mixon (Ohio State University)

Markov chain theorems for redistricting
Wes Pegden (Carnegie-Mellon University)

Visualizing and communicating data in alternative voting systems
Bridget Tenner (DePaul University)

Data and negotiation: Weighing complex and conflicting information in redistricting
Moon Duchin (Tufts University)




Data Science Education: 2020 Vision and Versions

HDSR 2019 Conference 2020 Visions and Versions

Chair and Moderator: Dustin Tingley (Harvard University)

Leading educators from multiple universities and disciplines will discuss their visions and initiatives in providing general data science education on their campuses, followed by Q&A.

Abel Hernandez:

On October 25, 2019, I had the opportunity to attend a comprehensive data science event from 7:30 AM to 6:00 PM. The day began with registration and breakfast, followed by an enlightening opening session. I was particularly intrigued by the discussions on differential privacy for the 2020 U.S. Census, which provided deep insights into the balance between data privacy and utility. The afternoon sessions on redistricting and data science education were equally captivating, offering fresh perspectives from leading experts. Overall, the event was a remarkable experience, highlighting significant advancements and interdisciplinary collaboration in the field of data science.
