Charted: Same-sex households across the U.S. - Axios

Same-sex couples make up about 1% of all U.S. households — a 30% increase since the Supreme Court legalized same-sex marriage nationwide.

Why it matters: Monday is the 8th anniversary of that ruling, Obergefell v. Hodges.

  • The growth in same-sex couples since then has varied from state to state.
  • Washington, D.C. has the highest overall share of same-sex households, followed by states on the East and West coasts.
  • The biggest increases in same-sex households since the court's ruling came in the Mountain West. Wyoming's share more than doubled between 2015 and 2021, and Utah's nearly did as well.
  • Only five states have seen a decrease from 2015 to 2021, including South Dakota, which had a 2021 nationwide low of 0.3% same-sex households.

What we're watching: Anti-LGBTQ+ legislation could slow or reverse these trends in some states.
