In 2007, Americans opposed legalizing same-sex marriage by a margin of 54% to 37%.
This is also not most people's first rodeo—many of them had two serious relationships before finding their spouse.
One factor driving this change is that Americans – particularly men – are staying single longer. Marriage declined most among those with a high school diploma or less education. The number of Americans living with an unmarried partner reached about 18 million in 2016, up 29% since 2007.
In 1990, 63% of this group were married; by 2015, that had dropped to 50%. marriage rate has declined, divorce rates have increased among older Americans. Roughly half of cohabiters are younger than 35 – but cohabitation is rising most quickly among Americans ages 50 and older. In 2013, 23% of married people had been married before, compared with just 13% in 1960.
A total of 15% of American adults have used online dating sites and/or mobile dating apps, according to a 2015 Pew Research Center survey, up from 11% who reported doing so in 2013.
Roughly four-in-ten Americans (41%) know someone who uses online dating, and 29% know someone who has entered a long-term relationship via online dating.
