Here is the probability you will break up with your partner

Published at Quartz with Dan Kopf for the Valentine’s Day special“breakup week”, I built an interactive “breakup calculator” based on Stanford’s How Couples Meet and Stay Together survey, which tracked real U.S. couples over five years. Readers could input details about their relationship — how long they’d been together, how they met, and how they rated it — and get a personalized probability of still being together in one, two, and five years, turning dry longitudinal data into something personal.
