SCOTUS Challenge to "One Person, One Vote" Will Most Impact These States

Our interactive map shows big potential shifts for California, Texas, and Nevada – home to 8.6 million noncitizen residents.

The Supreme Court this week heard arguments for a case that addresses the fundamental principle of “one person, one vote,” and could affect the political representation of more than 22 million people.

The case, Evenwel v. Abbott, is a challenge to the practice of state legislative lines being drawn in proportion to the number of people—citizens and noncitizens—that live in the state and not by the number of eligible voters.

While the current standard includes children and former felons, who cannot vote, it also includes noncitizens. As City Lab shows, any change would pinch Latinos especially.

Next America analyzed Census data to show which states have the highest noncitizen populations and would be most affected by a change to the law. Hover over each state to learn more about the size of their noncitizen population.
