At Big Think Ross Pomeroy reports on another study of the monetary value of a college education. Here are the results:
Zhang and his co-authors also pored through 2009–2021 data from the U.S. Census Bureau’s American Community Survey. Specifically, they compared the incomes of 2.9 million individuals with college bachelor’s degrees, ages 18 to 65, to the incomes of 2.9 million individuals with only high school diplomas.
“The earnings gap between college and high school graduates is around $14,000 annually,” Zhang told Big Think. “This gap is initially lower, then increases to about $20,000, and slightly decreases as they near retirement.”
Knowing the cost of attending a four-year university and the considerable income bump that comes with it, the researchers were then able to calculate the value of a college degree. They found that investment in a college education yields a return of about 9.1% for men and 9.9% for women. The higher rate for women is because female high school graduates earn far less than males. Over a 40-year career, these rates of return translate into millions of dollars of extra income.
While prepared to believe that graduating from college provides monetary value, I wish the article provided more information about the study. Unfortunately, the study itself appears to be restricted. Among my questions are:
- Did they calculate total income net of the cost of attending college? Or did they just compare incomes?
- Did they consider the extra years of income for those not attending college?
- Did they exclude individuals who went on after obtaining a four year college degree to attend medical school? A top law school? Get an MBA from a top school?
There are others.

Together, they estimated the total cost of attending a four-year college, using data from 1,160 public, 480 private nonprofit, and 230 for-profit institutions. Grant awards, tuition and fees, books and supplies, room and board, transportation, and opportunity costs from not working were accounted for in the tabulations. This brought the overall cost of college to roughly $140,000, Zhang told Big Think in an email.
makes me think they did consider the first two in their study but I’m not sure.
Any of those issues could render the study meaningless or at best change the results drastically.
Early in my career my college degree got me very little if anything and my having graduated from an elite school got me literally nothing. Bizarrely, no one cared about my post-graduate degree until recently.
