Voter I.D. Requirements Reduce Political Participation, Study Finds
A new report released by Brown University shows that requiring voters to present identification at the polls leads to lower levels of political participation. The research also suggests that voter I.D. policies discourage legal immigrants from becoming citizens. The authors conclude that voter I.D. requirements have a significant political impact – particularly on the Hispanic vote.
PROVIDENCE, R.I. [Brown University] — A new Brown University study reports that U.S. states that require voters to present identification before casting ballots have lower levels of political participation. The research also indicates that voter I.D. policies discourage legal immigrants from becoming citizens, particularly for blacks and Hispanics, reducing odds of naturalization by more than 15 percent. The full study, released by the American Communities Project at Brown’s Initiative in Spatial Structures in the Social Sciences (S4), is available online.
Since 2000, and stimulated by new security concerns after 9/11, there has been an upsurge in state requirements for voter identification. By 2004, a total of 19 states required some form of documentation of a voter’s identity, sometimes in the form of photo I.D. Proponents of such requirements believe identification is a necessary tool to prevent voting fraud, such as voting by noncitizens or people who are otherwise ineligible to register. Others argue that whatever its intention, I.D. policies have the effect of suppressing electoral participation, particularly among minorities.
The report, co-authored by S4 Director John Logan and graduate student Jennifer Darrah, concludes that voter I.D. is one of many factors that negatively influence civic participation in the United States. The report states, “At a time when many public officials express regret that immigrants seem to lag in their participation in mainstream society, even small suppressive effects on naturalization – the formal step to becoming an American citizen – work in the wrong direction and should be taken into account as people evaluate the benefits and costs of more stringent identification requirements.”
The new study extends previous research on I.D. requirements by analyzing not only voter turnout, but also voter registration and – “the key prior step for immigrants” – the decision to become a citizen, across racial and ethnic groups.
Key findings include:
“It is incredibly clear how voter I.D. requirements disproportionately affect and suppress minorities,” said Logan, professor of sociology. “This data shows that if voter I.D. policies had not been in place in 2004, voter turnout would have increased by more than 1.6 million. That is a strong argument in itself for change.”
The constitutionality of voter I.D. provisions is now under review by the U.S. Supreme Court with oral argument scheduled for Jan. 9, 2008. The case, Crawford v. Marion County Election Board, challenges the 2005 Indiana law requiring all voters who cast a ballot in person to present a photo I.D. issued by the United States or the State of Indiana.
This study, supported by a grant from the Russell Sage Foundation, is based on two more extended analyses of naturalization and political participation recently completed by Logan, Darrah, and Sookhee Oh, adjunct assistant professor of population studies. The complete studies, which provide additional technical details and full results of the multivariate models, are available online.
