Voting is a constitutionally protected right for eligible American citizens, but the path from eligibility to casting a ballot is not equally clear for everyone. Research consistently shows that certain groups face structural and practical obstacles that make voting more difficult, even when no law explicitly bars them from participating. Understanding those barriers requires looking at where they appear, who they affect most, and how they compound one another over time.
One of the most significant barriers is voter registration itself. Every state except North Dakota requires citizens to register before voting, yet millions of eligible Americans remain unregistered. In 2016, approximately one in seven voting-age citizens reported not being registered. Registration gaps fall disproportionately along racial, economic, and age lines: 69 percent of Black Americans and 57 percent of Hispanic Americans were registered that year, compared to 72 percent of white Americans, and a 20-point gap exists between the lowest and highest income brackets.
Registration deadlines create additional obstacles for many Americans. In 2014, arbitrary deadlines prevented an estimated 4.1 million people from registering, and in 2016, nearly a quarter of unregistered 18 and 19-year-olds reported missing their state's deadline. For Americans who move frequently, maintaining registration presents its own challenge. Black Americans, young people, and those living below the poverty line move at higher rates than other groups, leaving many voters removed from the rolls without realizing it.
Access to polling places shapes participation as well. Polling place closures and consolidations reduce convenience and create long lines that deter voters. In Maricopa County, Arizona, a 70 percent reduction in polling places during the 2016 primary forced voters to wait up to five hours. Long lines deterred at least 730,000 Americans from voting in 2012. These closures fall unevenly: in 2016, North Carolina had 158 fewer early polling places in counties with large Black communities, and Black voters nationally wait in line nearly twice as long as white voters on average.
Felony disenfranchisement laws remove voting rights from approximately 6 million Americans, a barrier that falls sharply along racial lines. In 2010, one in 13 Black Americans could not vote due to a felony conviction, compared to one in 56 non-Black Americans. Florida, Kentucky, and Iowa prohibit anyone convicted of any felony from ever voting again, even after completing their sentence. Some jurisdictions also fail to provide pretrial detainees with absentee ballots, disenfranchising people who have not yet been convicted of any crime.
Voter ID laws add another layer of complexity to the voting process for many eligible Americans. 36 states require voters to show some form of identification at the polls, and requirements vary widely, with 23 states specifically requiring photo ID. Laws requiring a physical street address can exclude Native Americans living on reservations and low-income residents who move frequently and may only have a P.O. box address. Voters who arrive to vote without acceptable identification may be required to cast a provisional ballot, and in strict ID states, must return with valid identification within a few days after the election for that ballot to be counted.
Young voters and college students face a distinct set of structural obstacles. Residency laws in some states require out-of-state students to either return home or establish legal residency in a new state, and ID requirements can compound this challenge for students who lack documentation tied to their college address. Young people also move more frequently and are more likely to hold jobs with unpredictable schedules that conflict with voting. Those aged 18 to 29 make up nearly 22 percent of the voting-age population but represented only 13 percent of the electorate in 2018.
Barriers related to language, disability, and access to information affect millions more. In 2016, people with disabilities participated at a rate more than 6 points lower than those without, and 60 percent of observed polling places had at least one physical impediment. An estimated 735,000 potential voters were blocked from registration in 2012 due to language barriers, and many first-time voters lack basic information about deadlines, polling locations, and identification requirements. In a 2017 survey, 6 percent of respondents said they were not registered simply because they did not know how to register.
Surveys show that most nonvoters cite disengagement rather than direct obstruction as their reason for not voting. In a post-2020 election poll, 35 percent of nonvoters said nothing would encourage them to vote, and 38 percent of unregistered nonvoters said they simply were not interested. But disengagement itself is shaped by the experience of repeatedly encountering systems that feel difficult to navigate, and for many Americans, those two things are impossible to separate.
