More than 36% of American women between the ages of 18 and 34 lived with their parents or other relatives last year. That’s the most since 1940. According to one Millennial who moved back home: “There was that element of frustration and feeling like a failure. But then the logical side of me kicked in and said, ‘It’s just fiscally responsible.'” (I’d move back home with my parents in a second if they’d stop asking for tech support.)
