Interracial marriage in the United States has been legal throughout the United States since at least the 1967 U.S. Supreme Court (Warren Court) decision Loving v. Virginia (1967) that held that anti-miscegenation laws were unconstitutional via the 14th Amendment adopted in 1868. Chief Justice Earl Warren wrote in the court opinion that "the freedom to marry, or not marry, a person of another race resides with the individual, and cannot be infringed by the State." The number of interracial marriages as a proportion of new marriages has been increasing from 3% in 1967 to 19% in 2019.
