This brief explains risk limiting audits, how they differ from fixed-percentage audits, and state adoption trends.

CEIR interviewed and surveyed election officials in four states—Arizona, Georgia, Nevada, and Rhode Island—to create case studies about their experiences planning, developing, and implementing a new voter registration database system.

This brief provides a current overview of post-election tabulation audits, state requirements, audit types, and policy considerations.

This report analyzes a Maryland bill that would require risk-limiting audits after statewide elections, including fiscal and administrative implications.

This paper introduces Bayesian/low-variance risk limiting audit approaches using marginal mark recording to reduce variability and sample requirements.

Over the last two decades, states have implemented several innovative policies that streamline the process of voter registration, promote voter list accuracy, and create more options for eligible citizens to register or update their voter registration. Such policy innovations include online voter registration, same-day voter registration, and automatic voter registration. The number of states that have implemented at least one of these three voter registration methods increased from seven states in 2000 to 46 states in 2024.

This report supports automated independent audits as a complement or alternative to other post-election audit methods. It may be useful for administrators or policymakers in comparing auditing approaches.

In this paper, authors use Orange County, California data to demonstrate efficient audit strategies for many contests and shows how contest selection by discrepancy can reduce workload.

This Article calls attention to the development and derailment of a novel cross-governmental bureaucracy for voter registration.

CEIR has surveyed states about voter registration database security every two years since 2018. These surveys have demonstrated widespread best practices in respondent states.

This paper examines an unintended consequence of automatic voter registration: effects on party registration. Examining the state of Oregon, a state with back-end AVR, the analysis documents a significant decreases in partisan voter registration rates.

Using data from Orange County, CA, this research finds that a variation of automatic voter registration that targets existing registrants as opposed to eligible nonregistrants—termed automatic reregistration (ARR)—increases turnout by 5.8 percentage points.
