10th Anniversary of Marriage Equality in Massachusetts

New research shows that up to 150,000 same-sex couples in the US are legally married

Analyses of survey and administrative data suggest that there are between 100,000 and 150,000 same-sex couples who are legally married in the United States today. This estimate implies that 15-25% of all same-sex couples in the country are legally married.

After 10 years of marriage equality in Massachusetts, analyses suggest that 80% of same-sex couples in the Bay State are married.  Data also suggest that the majority of married same-sex couples are female and that approximately 1 in 5 married same-sex couples live in the South, where marriage for same-sex couples is not widely available.

The Williams Institute analyzed data from Gallup’s Daily Tracking Survey (using data collected from June-December, 2013), Pew Research’s 2013 Survey of LGBT Americans, and administrative data collected from states that allow same-sex couples to legally marry to derive estimates.
