Twenty six years of enrollment at Public Research 1 Universities

A while ago, I made the claim that Oregon State University has the longest streak of consecutive years of fall-over-fall enrollment growth of any public, Research 1 university in America.  A few people have asked me, not exactly doubting the claim, but thinking maybe I had made a mistake, for the source of it.

This started as a curiosity: I knew from our own internal documentation that the last time OSU (the oldest OSU...not the one in Ohio or Oklahoma) had a fall-to-fall enrollment drop was 1996, and I was curious to see if any other institution could make that claim. So I went to the IPEDS Data Center and downloaded the data. 

It's below.  First, a few points: My comparison group is 108 Public, four-year, Research 1 Universities as designated by the Carnegie Commission on Higher Education as of Fall, 2022, the latest IPEDS data available. The R1 designation is actually called "Doctoral Institutions: Very High Research Activity" but the nickname R1 is a holdover from prior years. The category contains those institutions who produce the highest research activity and output among American universities.

What you can't see here is that 2023 showed an increase (it's not yet in IPEDS, but trust me), and that 2024 will also show an increase once our census is final.  So OSU's record is the 26 shown, plus last year, plus this coming year, for a total of 28 years.

There are a couple of small anomalies with the data, as there always seems to be.  First, some institutions missed a year or two in their reporting.  Even if those years had shown an increase, they were already nullified by other decreases. And Penn State has bounced around from being one institution to being several to being one again; this too does not seem to make a difference in the tally.

The first chart here shows all years and all institutions (you'll have to scroll down to see them all using the bar on the right.)  You'll notice that every institution shown (other than OSU) has at least two years with a blue box after 1997, meaning a decrease.  Hover over the box for details.  Orange shows an increase from the prior year.

The second chart shows individual enrollment data for any institution you select, using the filter at the top.  The bars are colored similarly: Orange for increase, and blue for decrease.

If I've missed something or you think these data points are wrong, let me know.  If a university decided intentionally to shrink, for whatever reason, that's interesting, but not the point of this visualization. If you want to look at just graduates or undergraduates or men or women or students of color or some other variable, I encourage you to read my posts here and here about how to download IPEDS data for yourself. 

And as always, leave a comment below if you find something interesting.

    Appreciate this data visualization. And congrats on impressive performance by Oregon State. At quick glance, it seems that -- after OSU -- Mines has the 2nd longer streak of fall UG enrollment gains (with consecutive increases since 2002). And University of Texas Dallas has the fewest number of fall over fall decreases (only 2 years of reported declines) during that time period. (Arkansas, Clemson, Georgia Tech, North Texas, TAMU, UC-Davis, UC-San Diego, UCF, UMass, and Mines all had only 3 years of declines.) Struck me how many land grant (& land grant adjacent [eg, GT, Mines]) institutions (and how few traditional non-Morrill flagships) have demonstrated consistent enrollment growth. Also, not surprising that public universities located on the coasts & within the Sun Belt seem to show more consistent increases than peers within the Great Lakes/ Midwest/ Plains states.

Changes in AP Scores, 2022 to 2024

Used to be, with a little work, you could download very detailed data on AP results from the College Board website: For every state, and for every course, you could see performance by ethnicity.  And, if you wanted to dig really deep, you could break out details by private and public schools, and by grade level.  I used to publish the data every couple of years. Those days are gone.  The transparency The College Board touts as a value seems to have its limits, and I understand this to some extent: Racists loved to twist the data using single-factor analysis, and that's not good for a company who is trying to make business inroads with under-represented communities as they cloak their pursuit of revenue as an altruistic push toward access. They still publish data, but as I wrote about in my last post , it's far less detailed; what's more, what is easily accessible is fairly sterile, and what's more detailed seems to be structured in a way that suggests the company doesn...

The Highly Rejective Colleges

If you're not following Akil Bello on Twitter, you should be.  His timeline is filled with great insights about standardized testing, and he takes great effort to point out racism (both subtle and not-so-subtle) in higher education, all while throwing in references to the Knicks and his daughter Enid, making the experience interesting, compelling, and sometimes, fun. Recently, he created the term " highly rejective colleges " as a more apt description for what are otherwise called "highly selective colleges."  As I've said before, a college that admits 15% of applicants really has a rejections office, not an admissions office.  The term appears to have taken off on Twitter, and I hope it will stick. So I took a look at the highly rejectives (really, that's all I'm going to call them from now on) and found some interesting patterns in the data. Take a look:  The 1,132 four-year, private colleges and universities with admissions data in IPEDS are incl...

Changes in SAT Scores after Test-optional

One of the intended consequences of test-optional admission policies at some institutions prior to the COVID-19 pandemic was to raise test scores reported to US News and World Report.  It's rare that you would see a proponent of test-optional admission like me admit that, but to deny it would be foolish. Because I worked at DePaul, which was an early adopter of the approach (at least among large universities), I fielded a lot of calls from colleagues who were considering it, some of whom were explicit in their reasons for doing so.  One person I spoke to came right out at the start of the call: She was only calling, she said, because her provost wanted to know how much they could raise scores if they went test-optional. If I sensed or heard that motivation, I advised people against it.  In those days, the vast majority of students took standardized admission tests like the SAT or ACT, but the percentage of students applying without tests was still relatively small; the ne...
