Tuition and Income in the States

Whoa, you might say as you look at this. It's way too funky for me. That's OK; I'm going to show you a new feature in the data visualization tool, Tableau, that I use that will make this all make sense. Hang on.

I wondered: Do states with higher median income levels charge more for tuition?  So I began to explore.

On each dashboard, median family income is displayed on the top chart, and college tuition on the bottom.  The view starts with four-year publics, but you can change it using the filter. The first dashboard shows only the rank of the states, from 1 to 5, with 1 being the high value in each.

If you can't make sense of it, don't worry: Use the little box in the upper right hand corner to select any single state, and that state's data will be instantly highlighted on both the income and the tuition chart.  You can see where a state stands on both measures.

The second dashboard (using the tabs across the top) shows the actual inflation-adjusted values (that is, $57,894 dollars in median family income, or $11,592 of tuition, both set to 2013), but the ranks are also displayed.  Use the state highlighter the same way, and hover over the dot for details. Note on this income chart I've broken one of my cardinal rules by not starting the y-axis at zero, for the sake of clarity.

You can get a sort of affordability index by looking at income ranks in comparison to tuition ranks, and you can see trends in both over time by state.

What do you notice here?



OK.  So maybe that's too funky.  Here's the same view, colored by red (high rank) to blue (low rank). If you like the original, it's below.

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

On Rankings, 1911, and Economic Mobility

If you're alive today, you have lived your whole life with college rankings.  Yes, even you.  You may not have knows you were living in the time of college rankings, but indeed, you have been, unless you were born before 1911 (or maybe earlier.)  If you're interested, you can read this Twitter thread from 2020 where I discuss them and include snippets of those 1911 rankings as well as those from 1957, written by Chesley Manly. You can read for yourself, or you can trust me, that in fact the rankings as we know them have been surprisingly consistent over time, and most people would have only minor quibbles with the ratings from 1911.  Perhaps that's because they have always tended to measure the same thing. But what if we did different rankings?  No, not like the Princeton Review where they make an attempt to measure best party school, or best cafeteria food, or worst social life.  Something more quantifiable and concrete, although still, admittedly, a hard thing to get rig

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
