 The number of same-sex marriages in Maryland continues to rise. The Census Bureau estimates there were only about 4,400 same-sex married couples in Maryland, 20 in 2012, the year before the state made same-sex marriage legal. That number has grown to 10,500 in 2015 when the Supreme Court ruled that marriage was a fundamental right that could not be denied to same-sex couples. Maryland Matters reporting that the number of married same-sex couples is now over 16,000 in the state. That's around 70% of all same-sex couples in the state.
