Almost one-third of married couples on Facebook were college sweethearts, according to a new study. And 15 percent of Facebook marrieds attended the same high school. The numbers come from Facebook's data science team, which analyzed anonymous data of U.S. couples over age 25 who classified themselves as "married" on Facebook. Couples who attended both the same high school and college were tallied as having met in high school.
"The count is a rough proxy for the chance of finding a spouse at the school,” said Facebook researcher Sofus Attila Macskassy. Though couples included in the study had to have attended high-school or college within four years of one another, there's no way to tell from the data whether they met/started dating while in school or after. The statistics also reflect primarily heterosexual married couples, Macskassy notes.
Interesting social patterns emerged from the data: Married couples who met in high school were more likely to come from rural than urban areas. Couples who met in college were more likely to come from small, conservative and religious colleges. More than half of Brigham Young University graduates on Facebook went "from classmates to soulmates," as Macskassy writes in a post about the research. Here are the rankings for which colleges were most likely to produce graduates with same-school spouses:
