Content: A standard error of 0.1 years is appropriate to measure sampling variability for any of the above estimated median ages at first marriage based on Current Population Survey data. Impact of Legalization of Same-Sex Marriage
The legalization of same-sex marriage in mid-2015 may have resulted in raising the average age of first marriage in the years that followed. Long-committed couples were finally able to be legally wed. One survey in 2017 found that the average marrying age for male-male couples was 46 and for female-female couples was 36. However, the trend had been upwards for male-female couples for decades and there is no obvious change in that rate from looking at the graphs. As those long-committed couples take the plunge, the demographics of same-sex couples getting married for the first time may come to resemble those of the general population. The State of Marriage
Pew Research Center, "marriage continues to lose market share among Americans to other arrangements, such as cohabitation or living alone. According to census data cited in the report, barely half of adults ages 18 and older are married — 51 percent in 2010, compared with 72 percent in 1960. This decline is especially notable for young adults: 20 percent of 18- to 29-year-olds were married in 2010, compared with 59 percent in 1960.
