When it comes to falling in love, it’s not just fate that brings people together—sometimes it’s their jobs. We scanned data from the U.S. Census Bureau’s 2014 American Community Survey—which covers 3.5 million households—to find out how people are pairing up. Some of the matches seemed practical (the most common marriage is betweengrade-school teachers), and others had us questioning Cupid’s aim (why do female dancers have a thing for male welders?). High-earning women (doctors, lawyers) tend to pair up with their economic equals, while middle- and lower-tier women often marry up. In other words, female CEOs tend to marry other CEOs; male CEOs are OK marrying their secretaries.
