In May 2024, RAND released a landmark report examining the impact of the freedom to marry for same-sex couples on American families and society at large. The two-section report offers groundbreaking analysis and original research evaluating the causal effects of changes in marriage policy across states with regard to marriage rates, divorce rates, and other outcomes in the general population. 

In October 2024, Boston Consulting Group released a new report to measure the personal and financial impacts of the freedom to marry for same-sex couples. The study is based in part on a survey of nearly 4,000 people in the US on the topic of marriage equality, with responses from a socioeconomically, racially, and geographically diverse cross-section of married and unmarried same-sex and different-sex couples

Using data from the American Community Survey and advanced statistical modeling, The Williams Institute estimated the number of couples currently married and examines their demographic and socioeconomic characteristics, finding that there are an estimated 823,000 married same-sex couples in the U.S. as of June 2025, more than double the number of married same-sex couples in June 2015 when Obergefell was decided. These couples are raising nearly 300,000 children. The percentage of married same-sex couples has increased over the past decade, with approximately 60% cohabitating same-sex couples being married today. Obergefell has had the most profound impact on the South, where the percentage of same-sex couples who are married increased most profoundly since 2015.
