CA Election 2020 Data Challenge

Data Science + Civic Engagement

The California Election 2020 Data Challenge was a month-long data science + civic engagement competition designed to leverage public data to help us understand this year’s ballot initiatives.

Participants built data literacy and visualization skills and contributed to informed civic dialogue by applying data science to questions about the November 3rd, 2020 CA ballot initiatives, which covered topics including health care, labor regulation, criminal justice, affirmative action, voting rights, affordable housing, consumer privacy, and tax reform. The outcomes of the Challenge were reproducible research projects culminating in a data visualization exploring an issue pertaining to a specific ballot initiative. This experiential education opportunity helped UC Davis students build their technical portfolios, explore publicly available data, expand their professional networks, and win $$$ prizes!

The Challenge was sponsored by UC Davis DataLab: Data Science and Informatics and the Scholars Strategy Network (SSN). Volunteer mentors and technical advisors contributed project feedback leading up to the challenge’s Virtual Showcase (Oct 5-6). Challenge finalists presented their projects at a public Webinar on October 21 (5-7pm), which featured keynote speakers Mindy Romero (founder and director of the Center for Inclusive Democracy), Jesse Salinas (Yolo County Clerk), and UC Davis Vice Provost of Digital Scholarship and University Librarian MacKenzie Smith

Challenge Results

Twenty teams of UC Davis students, scholars, and alumni submitted projects to the Challenge. The Challenge engaged over 100 participants, with nearly equal participation from graduate and undergraduate students. Several postdoctoral scholars, staff, alumni, and community members also participated in the challenge. Participants' backgrounds reflected the diversity of our campus, hailing from over 18 different domains and departments.

Teams developed a research question focusing on an aspect of a proposition on the California November 2020 ballot and leveraged public datasets to create a reproducible data visualization. While teams worked on 8 of the 12 ballot initiatives, the most popular propositions as selected by the teams were 17 (parolee voting rights), 18 (voting rights for 17 year olds), and 21 (rent control).

Projects were shared via an online asynchronous showcase and reviewed by over a dozen judges including UC Davis faculty, data scientists, and invited external reviewers. The judges were universally impressed with the quality, creativity and thoughtfulness of all projects completed for this short competition. Judges remarks included: “It was a real delight to get to hear about these projects and to explore their data and visualizations,” and “I was impressed by how smart, clever and creatively our UC Davis teams addressed this Challenge.” The Challenge mentors also praised the teams’ efforts to ask relevant, meaningful questions and to help inform civic dialogue. One mentor remarked: “While I know this wasn’t an explicit goal of the Challenge, the data presented by several of the projects even helped me decide how to vote.”

The winning projects most epitomized the Challenge’s goals of promoting data literacy and employed reproducible research methods to make data-driven storytelling accessible. These teams used innovative approaches to investigate thoughtful, civically-relevant questions. The three team finalists will present at the Challenge Finale Webinar on October 21 from 5 to 7 along with keynote speakers MacKenzie Smith (University Librarian and Vice Provost of Digital Scholarship), Mindy Romero (founder and director of the Center for Inclusive Democracy), and Jesse Salinas (Yolo County Clerk).

Winner: install.packages("tidywitches"): Prop 17

Team “Tidywitches” explored Prop 17, which would amend the California constitution to restore voting rights to people who have committed serious or violent crimes, who have been released from state prison but are now under state supervision (parole). Currently voting rights are restored after a person is released from state prison and has served their parole. While California has a huge population, there are many local elections in smaller-population counties where election outcomes are determined by a small number of votes. The team examined how many people are on parole in each county and how the restoration of their voting rights could have potentially influenced elections in five counties with high parolee numbers in 2018. Check out their interactive data visualization here.

Dr. Erica Orcutt received her PhD from the UC Davis Geography Graduate Group in December 2019. Her dissertation was on studying and modeling the habitat dynamics of the Mohave Ground Squirrel, which made her realize the fundamental importance of plants. She has been converted, and now works on remote sensing of plants in the Arctic for her postdoc in the Plant and Environmental Informatics Lab at UC Davis.

Laura Daly is a researcher and data analyst with Advancement Project California. Her research background is in civic engagement, election policy reform, and socioeconomic disparities, and she uses data to advocate for policy changes for more equitable outcomes. Laura earned her MA from the UC Davis Geography Graduate Group in 2017.

Sarah Byer is a Spatial/GIS Analyst with The Nature Conservancy in Nevada, and she specializes in spatial data science,cartography, and environmental remote sensing. Sarah earned her M.A. in Geography from UC Davis, designing a method to use satellite imagery to monitor drought-driven tree mortality in the Sierra Nevada mountains.

Winner: MissDemeanors: Prop 20

Team “MissDemeanors” explored Prop 20, which repeals parts of recent legislation to reduce prison overcrowding. Prop 20 would allow certain shoplifting, theft and fraud charges to be charged as felonies rather than misdemeanors and reduces possibilities for parole by re-classifying 51 crimes as ‘violent’ and therefore ineligible for early parole and allowing parole appeals by prosecutors. It also adds DNA collection for some current theft-based misdemeanors. This team focused on the historical relationship between CA legislation and overcrowding in prisons, asking if Prop 20 passes, will there be enough space for prisoners while staying under the supreme courts mandated 137.5% capacity ruling? Check out their interactive data visualization here.

Erin Calfee is a PhD Candidate in the Population Biology Graduate Group. She studies the genomes of honey bees and maize populations that have spread into novel environments to better understand the genetics of adaptation in these agricultural species. She’s passionate about using data and statistics for storytelling and shares the coding skills she’s learned in her PhD by teaching beginner courses in R.

Katherine Corn is a PhD candidate in the Population Biology Graduate Group studying macroevolution and biomechanics in coral reef fishes. Her work integrates macroevolutionary modeling and organismal biology to understand how changes in ecology and behavior over millions of years affect the functional diversity of fishes we have on coral reefs today. She enjoys using statistics to tease apart trends in large datasets as well as hiking, reading, and baking pastries.

Darien Satterfield is a behavioral ecologist, a PhD student in the Population Biology Graduate Group at UC Davis, and is studying functional morphology and behavior in fish. She specializes in the use of video and photography to collect data in the field with minimal disturbance to fish behaviors. Darien’s perspective is that visual media brings data to life and she strives to distribute her data in an accessible way to coastal communities who rely heavily on fish populations.

Winner: Catch-22: Prop 22

The “Catch-22” team explored Prop 22, which is concerned with determining whether app-based transportation (rideshare) and delivery drivers are “employees” or “independent contractors” and proposes that as independent contractors drivers receive certain benefits. As the most expensive proposition in California history this team dug into campaign financing asking who is supporting and funding this proposition and how much money have they raised over time. Check out their interactive data visualization here.

Trisha Ramadoss is a first year PhD student in the Transportation Technology & Policy program at UC Davis. She is working with the Plug-in Hybrid & Electric Vehicle center focusing on EV-grid integration.

About the Challenge

Overview

California voters are presented with an average of 10 ballot initiatives each election year. These propositions are an important way for Californians to shape the future of our state.

But, many voters say there are too many of them and that they’re too complicated and confusing to understand. Voters also often worry about their ability to make an informed decision. The CA Election 2020 Data Challenge is designed to leverage public data to help us understand this year’s ballot initiatives.

Participants working in teams of two or more selected one of the November 3rd, 2020 California Ballot Initiatives and, using at least one publicly available dataset, create a project culminating in a data visualization that explores or analyzes an aspect of the issue. Multiple teams could choose to work on the same ballot initiative but each team had to have their own unique research question.

This 2020 Challenge builds upon DataLab’s “PropFest 2018” where successful projects included pursuits that:

  • Analyzed potential impacts of a proposed initiative on specific regions, sectors and/or demographics;
  • Tracked and summarized the historical development of a proposition; and
  • Fact-checked rhetoric or claims on both sides of the debate.

By October 4th all competing teams uploaded a short (< 10 minute) video presentation of their project and data visualization (along with the link to the project’s public GitHub repository) to a Virtual Showcase which ran asynchronously on October 5th-6th. All teams were encouraged to submit their project (even if unfinished), review each other’s visualizations, and offer helpful, supportive, and constructive comments and questions. By observing the progress of the other teams, participants not only grow their network and skill set, but also gain insights to help improve their final project. And remember, the most collegial individuals also win a prize!

Judges reviewed all submissions and selected up to three finalists to win up to $500 and present their project to the broader campus community at the online Webinar on Wednesday, October 21 (5-7pm).

Prizes

Anyone from the UC Davis community and beyond was invited to participate on a team. Only current UC Davis students and postdoctoral scholars were eligible to win monetary prizes. Teams without a lead who is a current student or postdoc were welcome to participate but were not eligible for the prizes. Prizes were only be awarded to teams whose project focused on an issue relating to a single initiative on the November 3rd, 2020 CA ballot.

Team prizes were awarded for projects that are the:

  • Most accessible
  • Most innovative
  • Most data-licious

Individual prizes were also be awarded to the participants who demonstrated great collegiality, perseverance, and high engagement throughout the Challenge. This included providing helpful and supportive feedback and resources to other participants and teams on the Slack workspace, during the Showcase, and during other Challenge-related activities.

Expectations

The goal of this challenge is to support data literacy and explore data visualization applications to promote quantitatively informed civic dialogue. The emphasis of this challenge is on the process of working with data to uncover insights and providing an experience for applying data science to address real-world challenges. Your project and data visualization can encompass anything related to the ballot initiative, but this challenge will not support political agendas.

Full transparency of the data, code, outputs and interpretations is expected from all participants. In addition:

  • Projects must use at least one publicly available dataset.
  • All data visualizations must be reproducible. 

Teams must provide access to all materials used to produce their data visualization through a public GitHub repository. Best practices are expected for the organization of the repository, which should include all data, code, and outputs, along with a detailed readME explaining the files and links to the source datasets. 

For both the Showcase and Webinar presentations, teams should explain their data visualization, and highlight the process used for its development. At a minimum this presentation should include: 

    • Brief overview of the issue (your the research question) and its relevance for the given ballot initiative;
    • Where and how the data were obtained;
    • What tools, technologies, and techniques were used to analyze and visualize the data;
    • How they interpreted those findings;
    • What the data illuminates about a given issue pertaining to the ballot initiative;
    • Limitations of the source data or resulting visualization for understanding the issue

This Challenge provides an opportunity to learn and practice the process of developing a data science project. For the Showcase and Webinar, teams are encouraged to share any challenges they faced developing the project, how they overcame those challenges, and ask for suggestions and advice from others.
