This review of the literature was done for research to understand how voters approach the task of marking, reviewing, verifying, and casting a ballot. It includes not only research on voting systems and voting, but on related issues of trust, privacy, and mental models. This report is a companion to the research report NIST GCR 24-051 How Voters Review and Verify Ballots.

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.

This report summarizes projections of how many people with disabilities would be eligible to vote in the November 2024 elections, using data from the Census Bureau’s 2018-2022 American Community Survey combined with Census Bureau population projections for 2024. The report breaks down key demographic characteristics of eligible voters with disabilities.

This report describes qualitative research conducted to gain deeper insights about how voters mark, review, verify, and cast their ballots. It is part of the work to update the human factors—accessibility, usability, and voter privacy—requirements in federal voting system standards and fill gaps in our understanding of how voters interact with ballot marking devices.

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.

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 document is the third part of a series of documents on the usability of electronic pollbooks and is supplementary to Part Two in the series, Usability Testing for E-pollbooks: A
Test Protocol.

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 report is intended to assist election officials in developing poll worker training to support voters with disabilities at the polling place. This work is in response to the inconsistency of available training materials for poll workers on how to set up accessible voting systems and support voters in using them.

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 is the second part of a series of documents on the usability of electronic pollbooks. It outlines a procedure for how e-pollbooks might be evaluated, including a preliminary protocol for running a usability test. It can be used by people designing or purchasing an e-pollbook, as a usability component for a certification or approval process, or to determine aspects of the product that need special attention in training poll workers.
