Nobody knows how many colleges there are

If you ask the average person how many colleges there are in the US, the answer you get will depend on who that person is: If they work at the Wall Stree Journal or New York Times, they might say, "No more than 20." If you ask someone who thinks in terms of traditional post-secondary options where there is a campus quad and residence halls, you might hear "about a thousand." 

But how many are there, really? Now you might get close to the answer.  And, of course, the answer will depend on your definition. 

For Fall, 2019, IPEDS lists 6,527 post-secondary institutions in the US. There are more, but not every college in the US has to report to IPEDS. If an institution doesn't administer Title IV aid, it can operate without reporting data to the government. But the vast majority are there and ready for you to explore. 

This visualization is pretty simple: Two charts, one at the bottom which is static and shows the full 6,527 as a constant; and one at the top that changes as you make your selections along the right. Choose only four-year publics, for instance, and you'll see there are just over 800.  Add in two-year publics, and the number goes to 1,755.  The filters work in combination with each other, so you can get as granular as you'd like.

You can also split the view by using the control at the top.  Once you select the 1,685 four-year private colleges and universities, you can see where they are located by selecting "region" in the top control.

Play to your heart's content.  Reset using one of the left-pointing arrows.

And as always, let me know what you see.

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...

Freshman Migration, 1986 to 2020

(Note: I discovered that in IPEDS, Penn State Main Campus now reports with "The Pennsylvania State University" as one system.  So when you'd look at things over time, Penn State would have data until 2018, and then The Penn....etc would show up in 2020.  I found out Penn State main campus still reports its own data on the website, so I went there, and edited the IPEDS data by hand.  So if you noticed that error, it should be corrected now, but I'm not sure what I'll do in years going forward.) Freshman migration to and from the states is always a favorite visualization of mine, both because I find it a compelling and interesting topic, and because I had a few breakthroughs with calculated variables the first time I tried to do it. If you're a loyal reader, you know what this shows: The number of freshman and their movement between the states.  And if you're a loyal viewer and you use this for your work in your business, please consider supporting the costs...
