Where Do Your State’s Freshmen Come From?

By Matt Stiles | | Topics: Uncategorized

The Chronicle of Higher Education last month published an interesting piece about competition among universities for out-of-state students. 

Public universities across the country are engaged in an all-out war for out-of-state students. Deep cuts in support are driving the search for revenue, and in many states, a stagnating pool of local applications has pushed colleges to recruit broadly. The winners, like Arizona State, bring in higher out-of-state tuition and get to skim from a larger pool of prospective students.

They also posted several interactives to help tell the story, including maps and treemaps visualizing out-of-state students by campus (in this case for George Washington University): 

The interactive, created by Josh Keller and Alex Richards, also included bar charts showing the percentage of students from various states by campus, allowing users to navigate the data to find their own stories. Campuses in Washington, D.C., for example, had the highest proportion of students from outside. Texas had the lowest rate: 

Nice work, guys.

Spanish Soccer Discipline

Discipline varies widely in the Spanish first-division soccer league, or La Liga. These stats from last season group yellow cards violations by team and player. Real Zaragoza received 63 yellow cards. Sevilla FC, conversely, received just seven. The two marque teams in the league — Real Madrid and Barcelona — received 31 and 9, respectively.

How The American Diet Has Changed Since 1980

By Matt Stiles | | Topics: Uncategorized

Thanks to the U.S. Census Bureau, I learned this week that Americans eat on average about 21 pounds of rice each year — and they wash it down with about 13 pounds of ice cream, apparently.

I wondered, what else do Americans eat, and how has that changed over time? Using the bureau’s “Per Capita Consumption of Major Food Commodities” report, I created this treemap, which visualizes hierarchical data structures that have categories and subcategories.

Red meat, for example, is a category of food that consists of beef, lamb and mutton, pork and veal. The same goes for sweeteners: sugar, corn sweeteners and high-fructose corn syrum. And so forth.

Thanks to Many Eyes, the treemap shows which categories of food are consumed at the highest volumes, and also the proportion of the various sub groups. It also shows how that consumption has changed over time.

This view shows category and food volumes by sizes and change with colors (orange represents growth; blue represent declines):

Right click on a category to zoom in and isolate it on the map. Doing so on sweeteners, for example, shows that we still consume lots of them (173 pounds a year on average), but that sugar consumption has declined by 22 percent since 1980. (That’s largely because it’s imported and expensive). We also see that high-fructose corn syrup consumption has increased 180 percent. (That’s largely because it is widely used as a sugar substitute in processed foods and soft drinks). It’s no wonder that products like the phenq diet pill are so popular in America. Hover over the foods to see values:

Go check out the interactive version, which is easier to understand. Experiment with views by switching the “Category” and “Commodity” tags at the top of the map. You can also change the years to examine change over shorter periods of time.
