What is a majority-minority district?
A majority-minority congressional district is one in which a racial or ethnic minority group, such as Black, Hispanic, or Asian American voters, makes up more than half of the population or voting-age population. Supporters of such districts say they give minority communities a realistic opportunity to elect candidates of their choice in areas where voting patterns are racially polarized. Critics say drawing lines around voters by race raises constitutional concerns.
How redistricting works
After each decennial census, states redraw their congressional district boundaries to reflect population shifts. In most states, the legislature draws the maps, though some use independent or bipartisan commissions. New maps can be challenged in state or federal court on a variety of grounds, including alleged racial discrimination, partisan gerrymandering under state law, or violations of one-person, one-vote requirements.
The Voting Rights Act framework
Section 2 of the Voting Rights Act of 1965 prohibits voting practices that result in the denial or abridgment of the right to vote on account of race, color, or membership in a language minority group. Under a series of Supreme Court decisions, plaintiffs challenging a map under Section 2 generally must show that a minority group is sufficiently large and geographically compact to form a majority in a district, that the group votes cohesively, and that the white majority votes as a bloc to usually defeat the minority's preferred candidates.
The Equal Protection counterargument
The Fourteenth Amendment's Equal Protection Clause limits the government's ability to classify people by race. In cases such as Shaw v. Reno (1993) and Miller v. Johnson (1995), the Supreme Court held that when race is the predominant factor in drawing district lines, the map is subject to strict scrutiny and may be struck down. Critics of mandated majority-minority districts argue that ordering states to draw lines based on racial composition is in tension with this principle.
Recent Supreme Court action
In its 2023 decision in Allen v. Milligan, the Supreme Court upheld Section 2 as applied to Alabama and ordered the state to draw a second majority-Black congressional district. Black residents make up roughly 27 percent of Alabama's population, and the state has seven congressional districts. On June 3, 2026, the Supreme Court cleared the way for Alabama to use a congressional map that eliminates one of the state's two districts where Black voters made up a majority or near-majority, signaling a continued evolution in how the Court applies the standard.
The case for court-ordered majority-minority districts
Supporters say that in places with a history of racially polarized voting, minority voters can be effectively shut out of representation when their communities are split among several districts or packed into a single one. They argue that judicial enforcement of Section 2 is necessary because state legislatures may have political incentives not to create such districts on their own, and they point to the Voting Rights Act as a long-standing bipartisan response to documented patterns of vote dilution.
The case against court-ordered majority-minority districts
Critics argue that requiring states to sort voters by race, even with the goal of remedying past discrimination, conflicts with the constitutional principle of equal treatment under the law. They contend that race-conscious districting can entrench racial categories in politics, reduce competition, and substitute judges' judgments for those of elected lawmakers. Some also argue that as voting patterns and demographics change, the original justifications for race-based districting are weaker than they once were.
What could change the rules?
The current framework rests on a combination of the Voting Rights Act and Supreme Court precedent. Altering it would require either a new ruling from the Supreme Court reinterpreting Section 2 or the Constitution, or an act of Congress amending the Voting Rights Act. State legislatures can also shape outcomes by how they draw maps in the first place, subject to judicial review.
