College Costs Linked to Risky Teen Behavior

New research links the cost of community college tuition rates with drinking and drug use by teenagers.

Why do some teenagers engage in risky behavior such as drinking, drug use and multiple sex partners? Washington State University economist Ben Cowan has discovered a startlingly simple correlation that provides at least part of the answer.

The more it costs to attend community college, the more likely it is that teens will act in self-destructive ways.

“I find that lower college costs in teenagers’ states of residence raise their subjective expectations regarding college attendance and deter teenage substance use and sexual partnership,” Cowan writes in the Economics of Education Review.


Cowan analyzed data from the 1997 cohort of the National Longitudinal Study of Youth, which features behavioral information on a cross section of Americans who were between the ages of 12 and 16 in 1996. His final sample featured nearly 5,000 young adults.

He compared those findings with state-by-state data on community college tuition rates. The cost to attend two-year schools varies tremendously, from $4,000 to $5,000 for a full-time student in New York and Massachusetts to under $2,000 in seven states. (The figures are from the 2009-10 school year.)

Cowan controlled for a wide range of factors, including family income, parents’ education level and stability of family life (measured by whether the child was living with both biological parents at age 12). Taking all that into account, he found that “teens living in states in which two-year college is relatively inexpensive engage in lower levels of sexual activity, smoking, heavy drinking and marijuana use.”

What’s more, he found community college tuition rates have “the largest effect on youths who are plausibly closest to the college enrollment margin.” In other words, those kids who may or may not attend college are more likely to ultimately enroll in two-year facilities — and they are the ones whose behavior is most strongly impacted by tuition rates.

“These findings suggest that the often-studied correlation between schooling and health habits emerges in adolescence because teenagers with brighter college prospects curb their risky behavior in accordance with their expectations,” Cowan writes.

To turn that statement around: Kids who see the prospect of a college education, and the better life it promises, slipping away from them have little incentive to check their self-destructive impulses.

“For policymakers wishing to discourage teenage drug use and risky sexual activity, my results imply that tuition policy may be an effective way to do so,” Cowan concludes. Of course, many states are moving in the opposite direction, raising community college tuitions to deal with their budget deficits.

Cowan admits lowering rates would be expensive, in that there are more than 6 million students enrolled in public two-year colleges in the U.S. But he adds that targeting youth “near the college-decision margin” could make such an effort more cost effective.

His research adds to the evidence that cutting funds for higher education has unseen costs that will negatively impact society in the long run. The cliché “Do you want to fund colleges, or prisons?” can be amended to also ask: “Do you want to fund colleges, or drug rehab centers?”
