Criteria for inclusion: stand-alone college towns with a population less than 90K and a public university larger than 10K enrollment. Dataset may not include every example of this, but diligent efforts have been made to be as complete as possible. The orange line shows the best-fit linear regression model. Any place above the line has more than its projected population based on enrollment. (Added 7:30 PM, June 23, 2023)

Tim Keller (no relation) stated in the article “Guest Commentary: How Big Does Davis Need to Be? College Towns Analysis Part 3 – Long-Term Planning” that “In previous articles we saw evidence that suggests that a population of 120,000 might be entirely appropriate for a university town such as Davis: It is the size of Ann Arbor, Michigan (home of the University of Michigan), Champagne-Urbana (home of the University of Illinois), and Lafayette Indiana (home of Purdue). These are all well-regarded and well-funded research universities of very similar size and character to UC Davis.”
For reference, the 2022 population of Davis was 67,048, and Tim’s number is a huge 179% increase above that.
The so-called “evidence” that he based this on was a very incomplete, cherry-picked, and in some cases factually-inaccurate, list of 17 universities and host towns to compare to Davis.
He stated “The trend that emerges immediately is that the population of a “university town” such as ours tends to be about 3x the size of its student body.”
I have access to a more complete database of 40 public research universities with enrollment of at least 10,000 students (and up to 50,000), located in distinct host towns with populations less than 100,000. Tim ignored the vast majority of these. It turns out that the median population-to-student enrollment ratio of these 40 college towns is almost identical to that of Davis (Davis is slightly higher), which completely undermines his argument that Davis needs massive population growth to support current university enrollment.
If Tim hadn’t approached the exercise with an endpoint in mind—his preconceived notion that Davis need to be much larger than it is—he could have done a more credible analysis. His limited cherry-picked data had some basic facts wrong. The 2022 population of Corvallis was actually 60,956 (not 95,184), and the population-to-enrollment ratio is actually 1.73. And he drastically understated the enrollment for the University of Indiana at 35,253, when Fall 2022 enrollment was actually 47,005. The population-to-enrollment ratio for Bloomington is actually 1.68. With Davis at around 1.9, these two cases, as well as the median of 1.82 for the larger dataset, indicates that Davis has more population per enrollment than the norm.
I won’t get into a critique right now of Tim’s notion that a simplistic and crude comparison of population size to university enrollment should provide prescriptive guidance. But suffice it to say for now that a more through examination of the facts using a more complete dataset of college towns, points to the opposite conclusion that he had.
Should we be surprised that one of the people behind the “Sustainable Growth Yolo” organization is advocating for massive amounts of growth based on faulty analysis and assumptions? I’m not sure why they aren’t more honest and just delete the “sustainable” part.

This will mark the start of a new era with a Davis Vanguard free of housing articles, signed under the Treaty of White, named after our long-departed Innovation Officer, for no reason in particular. Or the color white, I'm not sure.
The Vanguard will now focus on its true passion: cooking with fish. Lots of articles on cooking with fish.
Now if only Ron O. would just get over the notion that Measure J or Rent Control were good ideas.
Oh, well. Baby steps. ;-)
That should elicit an essay for the Davisite. On Housing :-|
What have I done?
