UCLA sociologist Jennie Brand set out to answer a question that sounds simple but matters enormously: Does college change everyone the same way? After studying 12,686 Americans tracked from their teenage years in 1979 all the way through their early 40s in 2008, she discovered something that challenges how we think about education's promise.
The finding is striking because it reveals an unexpected inequality hidden inside what looks like equal opportunity. College graduates volunteer at the same rates across all social backgrounds—about 15 percent engage with civic, community and youth groups regardless of whether they grew up privileged or disadvantaged. On the surface, this suggests college works fairly for everyone. But the real story emerges when Brand compared college graduates to their non-college peers from identical backgrounds and with similar ability levels.
For disadvantaged students, the difference is transformative. College graduates from underprivileged backgrounds were up to 10 times more likely to volunteer for civic, community and youth groups than non-college graduates from the same circumstances. That's a staggering lift. By contrast, more advantaged college graduates were only twice as likely to volunteer compared to their non-college peers—a substantial boost, but fundamentally different in scale. The gap is so large that Brand describes the college effect for disadvantaged graduates as five times greater than for their advantaged counterparts.
The numbers illustrate why this matters. Just 1.5 percent of disadvantaged non-college graduates volunteer for civic groups, compared with 7.5 percent of advantaged non-college graduates. But once disadvantaged students attend college, they reach 15 percent—matching their more privileged peers exactly. College doesn't just improve their odds; it erases a gap that poverty and limited education would otherwise cement across generations.
Brand's research, published in the peer-reviewed journal Social Forces, examined two categories of volunteering: civic, community and youth groups like the League of Women Voters and Little League, plus charitable and social welfare organizations like the Salvation Army and soup kitchens. The pattern held in both areas, though the effect was most dramatic for community involvement. For charitable work, disadvantaged college graduates proved four times more likely than non-college peers to participate, while advantaged graduates showed no measurable difference from their non-college counterparts.
The mechanisms behind this transformation likely include what Brand calls the "college effect"—exposure to educated peers, expanded social networks, and direct teaching about civic norms and responsibilities. For disadvantaged students, these influences appear particularly powerful, perhaps because they represent a break from environments where such opportunities are scarce.
Brand emphasized that this isn't about disadvantaged graduates becoming more civically minded than privileged ones. Rather, college creates a floor that lifts disadvantaged students out of the significantly lower volunteer rates that characterize their communities overall. Without a degree, economic strain, job insecurity, single parenthood, and health challenges create barriers to volunteering that privileged people navigate more easily. College doesn't eliminate these pressures, but it appears to fundamentally reshape how people in disadvantaged circumstances engage with their communities.
The research suggests that college's real power for equity lies not in making everyone equal, but in breaking cycles. For students from underprivileged backgrounds, a degree becomes not just an economic passport but a gateway to the kind of community participation that strengthens neighborhoods and sustains democratic life.
