Who lives here
Most of this district's voting-age residents (84.6%) belong to minority groups. The largest are Black (45.9%) and Hispanic or Latino (32.4%). The Voting Rights Act can require districts that keep a minority community together so it can elect candidates it prefers, and those districts can be irregular on purpose. A district like this isn't necessarily drawn for that reason, and the site doesn't know whether this one was. Figures are from the 2020 Census. How these are counted
