Both Andrea and Alexis are examples of “helicopter parents,” defined by their hovering and readiness with supplies, assistance, and guidance. Their interventions were costly—requiring time, financial reserves, social savvy, comfort with authority figures, and knowledge of higher education—though they had different purposes. While Andrea was a focused on her daughter’s human capital—the skills, credentials, and knowledge that often lead to career success and economic security—Alexis was invested in her daughter’s social and extracurricular activities, consumption, and sorority status. Her husband explicitly told their daughter to “marry rich” in the years after college.

I had the chance to observe these parents—and many others—from 2004 to 2009, when I followed 41 families as their children moved through a public flagship university. (As is typical practice in sociology research, the name of the university will remain anonymous—but it is representative of a typical experience for many public-university students across the U.S.) Parents of college students are rarely studied. However, many U.S. universities, particularly those lacking the deep pockets and extensive resources of elite privates, have come to rely on parents to fill numerous financial, advisory, and support functions.

My focus on parents of daughters was not incidental, as today the majority of college students are women; they enroll in and complete college at higher rates than men. The university these women attended has increasingly catered to out-of-state families who are willing to pay full tuition and board in exchange for a degree from a “name” school. And while the number of families I studied is small, I made up for it with depth of knowledge: All the students started college in same residence hall, where I observed them during their first year, after which I interviewed them every year for five years. As the women approached graduation, I also interviewed both their mothers and fathers.

Most—but not all—of the parents in my sample fell neatly into several categories. About two-fifths were “helicopter” parents like Andrea and Alexis, regarded in the media as among the most reviled figures of 21st-century parenting—pesky interlopers who test the patience of school officials, meddle with university affairs, and raise a generation of “coddled,” “entitled,” and “under-constructed” youth.

Yet intensive parenting is, in many ways, a logical response to the harsh risks facing young people during college and early adulthood. Increasing income inequality, high rates of young-adult unemployment, and a decline in stable and well-paying entry-level jobs loom threateningly in the foreground. Declines in state and federal support for higher education, coupled with rising administrative costs in a complex regulatory environment, have led to skyrocketing tuition. Additionally, the sheer diversity of academic and social options, particularly at large public universities, makes it easy for college students to make costly mistakes. Involved parents provide insurance against risk.
