Cory McCartan presents "Measuring and Modeling Neighborhoods", at CGIS Knafel Building (K354) - 12:10-1:30 pm, Wednesday, September 29, 2021

More granular geographical data has allowed social scientists to probe how residential neighborhoods are formed and how they influence attitudes and behavior. To facilitate such studies, we develop a survey tool that allows respondents to draw their neighborhoods on a map. We propose a hierarchical Bayesian model that can be used to analyze which factors shape their neighborhoods. We have conducted a survey of registered voters in Miami, New York City, and Phoenix, and  find that across these cities, voters are more likely to include same-race and co-partisan census...

Sherry Zaks presents "Do we know it when we see it? Conceptualization and Cascading Bias in Identifying "Rebel-to-Party Transition"", at CGIS Knafel Building (K354) - 12:10-1:30 pm, Wednesday, September 22, 2021
Studies on rebel-to-party transition suggest that incorporating former-rebels into post-conflict politics creates a tenable path toward stability and democratization. Notwithstanding the salience of these results, the rebel-to-party literature is racked with an unacknowledged conceptual tension that simultaneously demands---and paves the way for---reconciliation. On the one hand, scholars exhibit remarkable convergence on both the core meaning and stakes of rebel-to-party transition. On the other hand, the literature reveals nearly as many different definitions of "rebel-to-party transition"... Read more about Sherry Zaks presents "Do we know it when we see it?

Christopher Kenny presents "The Use of Differential Privacy for Census Data and its Impact on Redistricting: The Case of the 2020 U.S. Census", at CGIS Knafel Building (K354) - 12:10-1:30 pm, Wednesday, September 15, 2021
Census statistics play a key role in public policy decisions and social science research. Yet given the risk of revealing individual information, many statistical agencies are considering disclosure control methods based on differential privacy, which add noise to tabulated data. Unlike other applications of differential privacy, however, census statistics must be post-processed after noise injection to be usable. We study the impact of the US Census Bureau's latest Disclosure Avoidance System (DAS) on a major application of census statistics---the redrawing of electoral districts. We find...
