the numbers behind Jake and Maria
Jake and Maria are drawn, but the numbers around them come from the How Couples Meet and Stay Together survey, which the Stanford sociologist Michael Rosenfeld and his colleagues published in PNAS in 2019, from Pew Research Center, and from a 2017 paper by the economists Josué Ortega and Philipp Hergovich called The Strength of Absent Ties.
In that survey, 2 percent of straight couples who got together in 1995 had met online, a share that climbed to 22 percent by 2009 and 39 percent by 2017, while the share who met through friends fell from 33 percent to 18 percent over the same years.
The two lines crossed in 2013, at 30 percent online against 20 percent through friends, and by 2024 The Knot's survey of couples put the online share at 60 percent, while for same-sex couples meeting online was already the most common route in 2009, at 61 percent, and reached 65 percent by 2017.
Of the couples who met online, 89 percent had no friend in common before they met, according to the 2017 wave of the same survey, which is the whole point of this story, because no cousin or colleague could have put a man in Ohio in touch with a woman in Lisbon.
The share of American newlyweds marrying someone of a different race or ethnicity rose from 3 percent in 1967 to 19 percent in 2019 in the Pew figures this page uses, and when Ortega and Hergovich modelled a society in which strangers start meeting through apps, their model predicted a rise in interracial marriage of exactly this kind.
