Using this tool, NCSL tracks and classifies voter ID laws across all 50 states along two dimensions: whether they require voters to present an ID and whether the requirement is strict or non-strict.

Academic paper examining the use of audits following elections to improve voter confidence.
In this paper, authors compare electronic and paper ballot voting systems, examining how election laws directly impact operational efficiency and capacity, and what this means for polling place design and resource allocation.
The biennial comprehensive survey of election administration across all 50 states, five territories, and D.C., covering the 2022 midterm general election—widely seen as a return to normal operations after the COVID-19-disrupted 2020 election. Key in-person voting findings include: 645,219 poll workers assisted with early and Election Day voting, including more than 80,000 first-time poll workers (16.7% of the total); election officials reported that poll worker recruitment was meaningfully easier than in the 2018 midterms; e-pollbook adoption grew significantly, with 2,271 local jurisdictions in 40 states using them (up 60% from 2008); nearly all states (94.6%) reported conducting logic and accuracy testing of voting machines before tabulation; and the 2022 EAVS collected data on drop boxes and ballot curing for the first time, finding nearly 13,000 drop boxes in use nationally. The survey also covers voter registration, UOCAVA voting, absentee voting, provisional balloting, and voting technology across all reporting jurisdictions.
This paper present a case study examining the implementation of Election Day vote centers, finding that successful adoption requires coordination across multiple elements of the election ecosystem.
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.
The SMILE series are instructional videos, based on over 8,000 simulations, that help election officials visualize cost-effective resource allocations for polling locations that keep wait times under 30 minutes. The series covers polling place consolidation, new equipment integration, and allocation of accessible voting technology.
In this paper, authors provide recommendations from disability voting rights advocates on how to improve the physical accessibility of polling locations and the usability of accessible voting equipment.
This paper examines whether minority and Democratic-leaning voters in Florida receive lower poll worker staffing. Using data from multiple elections, authors find evidence of partisan disparities in staffing levels, with Democratic-trending counties receiving worse service relative to Republican-trending counties. They apply operations management methods to document systemic resource allocation inequities in polling place operations.
This report provides practical guidance for conducting tabulation audits, with discussion of audit methods and links to risk limiting audit resources.
This paper challenges the HAVA minimum of one ADA-compliant device per polling location as insufficient and recommends that local election officials determine the number of accessible devices based on the proportion of voters with disabilities in their jurisdiction.
In this PhD dissertation, Schmidt introduces optimization and simulation models to support the design and operation of resilient in-person election voting systems. Three core contributions: (1) a discrete-event simulation of pandemic-resilient polling-place design, with a case study of Milwaukee, WI; (2) the Polling Location Consolidation Problem (PLCP), an integer programming model applied to Richland County, SC; and (3) an optimization model for ballot drop box siting in Milwaukee.
