The Census Bureau reported Thursday that the nation’s marriage rate is the lowest since 1920, and the first-time inclusion of same sex married couples did little to reverse the decline.

According to Pew Research Center analysis, the marriage rate of Americans 18 and older hit a bottom of 50.3 percent in 2013, down from 50.5 percent in 2012. In 1920, the first year mentioned, 65 percent were married, and the marriage rate hit a high of 72.2 percent in 1960.

The new data did not put a number on the homes hosting same-sex married couples, though the Census last year estimated there were 182,000 households headed by gay couples.

While a big number, Pew noted that it compares with 56 million “headed by opposite-sex married couples,” and that such a small percentage won’t have a big impact on the overall marriage rate.
