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.

After discussions with election officials from Los Angeles County, Colorado, Georgia, and Texas, this project used messaging experiments with nearly 8,500 Americans following the 2022 U.S. midterm elections to measure the impact on trust. It found that state and local election officials can be strongly effective at increasing trust in their own state elections.
This academic article studies how messages from political elites influence public confidence in elections and acceptance of democratic norms. It is relevant to the dataset because it connects election rules, information environments, or administrative performance to public confidence and perceived legitimacy. For this dataset, it adds evidence on one of the recurring drivers of election trust: experience, information, partisanship, security, or institutional performance.
This report examines the impact of voting laws on voter turnout and choice of voting method (referred to from here on as voting method) in the 2020 election and the effects of in-person voting on the spread of COVID-19.
This paper argues state investment in voter education strengthens voter confidence by improving voter experiences and creating a culture of voter education, both of which facilitate transparency in elections.
In this paper, authors examine how decisions made by the USPS in the latter part of the nineteenth and early twentieth centuries have resulted in deeply entrenched structural inequities in the access to mail services on the Navajo Nation in Arizona when compared to rural nonreservation communities. These findings bear significant implications for mail ballot access by those of the Navajo Nation.
Using surveys of registered voters conducted in April and May 2020 designed to assess the support for various electoral reforms, the research shows that the overall support for expanding VBM in April 2020 falls sharply after just six weeks because Republicans became less worried about catching COVID-19, and unconcerned Republicans became far more opposed to VBM. These differences not only persisted, but actually increased even further between May and Election Day according to a survey done using a different methodology in November 2020.
This research assesses whether messages reinforcing election integrity increased participation in the 2020 election through a large-scale voter mobilization field experiment. California registrants were mailed a letter that described either existing safeguards to prevent vote-by-mail fraud or the ability to track one’s ballot and ensure that it was counted. Analysis of state voter records reveals that neither message increased turnout over a simple election reminder or even no contact.
While the evidence is clear that 2020 voters shifted away from Election Day voting in favor of vote-by-mail and early voting, very is known about how health risk versus party polarization around risk assessment influenced how and when to vote. The research finds that age and party were large factors in vote mode decisions in 2020, but not in 2016 or 2018.
Drawing on a large survey of validated Florida voters, including those who regularly vote by mail, the research finds that retrospective and prospective misreporting of vote method prior to the 2020 General Election was driven primarily by support for Trump. The president’s supporters who were most politically aware were most likely to disavow their own voting by mail and misreport their anticipated vote method in the November election.
This research finds even in the absence of elite claims of vote fraud, authors see strong and immediate shifts in mass views. Once the results became clear, those who supported the losing side became significantly less likely to trust that votes were counted correctly or to be satisfied with the election process, while trust and support for the process rose from pre-to post-election for voters on the winning side.
This research finds that voters with greater general political knowledge are more likely to vote early, and those with low political knowledge are more likely to wait until Election Day to cast their ballot.
