This issue brief provides an overview of absentee and mail voting in the U.S.. Authors provide a brief history of mail voting, and note an increase in mail voting since the COVID-19 pandemic. It spotlights Oregon's early adoption of vote-by-mail (VBM) and explores current discourse regarding whether VBM increases voter turnout, and concerns over electoral integrity.

In this PhD dissertation, Houghton develops advanced algorithmic methods to model voter arrival behavior and vote center utilization to support election resource and capacity planning. Three core contributions: (1) compares voters’ demographic characteristics across three vote center types during the 11-day voting period across multiple elections; (2) analyzes how voters choose among multiple available vote center locations by using graph-based methods to analyze network data and perform statistical community detection; and (3) uses spatial access metrics as input to a genetic algorithm to optimize location selection for vote center siting decisions.

The analysis suggests that ballot drop boxes and automatic ballot notification systems are crucial for reducing the attack surface to ensure secure and reliable operations.

Overall, 1.5 percent of all primary ballots cast and 1.1 percent of general election ballots cast were rejected across elections from 2012 to 2022 in Washington. There is evidence that voters of color have higher ballot rejection rates than White voters. Self-identifying male voters have slightly higher ballot rejection rates than self-identifying female voters in both primary and general elections. Younger voters have a much higher ballot rejection rate than older voters.

In this paper, authors examine how polling place closures following the Supreme Court's Shelby County v. Holder decision affected voter wait times during Georgia's 2016 presidential election. Using queueing theory and empirical data, it quantifies the impact of consolidating polling locations on wait times, with particular attention to how closures affected different communities. Authors provide evidence linking post-Shelby polling place reductions to measurably longer lines.

This report provides a comprehensive analysis of absentee/mail voting and early in-person policies between January 2020 (pre-pandemic) and November 2022. This research highlights that most absentee/mail voting policies were not significantly affected by the pandemic. If changes were made to policies for the 2020 election, they reverted to the policy existing prior to the pandemic.

This resources provides a step-by-step protocol for test voting system usability and accessibility functions in use, including how well the ballot presents voters with options and allows them to confirm their choices while marking and verify their ballot before casting. This resources is intended for state certification programs and election offices evaluating a new voting system.

In this paper, authors develop an algorithm that can reduce racial disparities in polling place access by suggesting improved placements for polling places from a list of identified public locations at the state level.

This study demonstrates that the level of accessibility of state absentee and mail voting laws as well as their administration have significant effects on voter turnout. The results also reveal that higher performing U.S. Postal Service administration can enhance the impact of absentee and mail voting laws, particularly in states with the most restrictive mail voting laws.

This paper uses geographic discontinuities at block boundaries to identify the causal effect of polling place assignment on voter turnout, finding that distance to and familiarity with a polling location matter for participation.

This brief documents the emergence and growth of mail balloting and details the unique administrative arrangements associated with this method of voting, related research and best practices, and areas where there is still more to learn. Voting by uniformed and overseas citizens—"UOCAVA” voters—is a special case not focused on in this report.

This report provides a comprehensive review of the existing literature on in-person voting to determine best practices and identify areas where more research is needed, covering both operational features and the voter experience.
