Things are different today, or so everyone says. If you want to see how admit rates have changed over time at any four colleges, this is your chance. Just follow the instructions and take a look to compare how things have changed over four years. The view starts with four similar midwestern liberal arts colleges, but you can compare any four of your choice. (And before you ask, 2016 is the most recent data available in IPEDS).
And, a note: These changes are not all driven solely by demand. Colleges can manipulate overall admit rates by taking a larger percentage of their class via early programs, and admit rates in those programs can be as much as 30 points higher than in regular decision.
