Data on in-state vs out-of-state students by State

Kevin Helliker over at the Wall Street Journal (see here) has an article today about states who draws lots of college students from other states (emphasizing the success of North Dakota in drawing students from other states).  It has an interactive data table showing the number (and percentage) of in-state students versus out-of-state students.  According to the data, about 86% of Mississippi public university students are "in-state" and about 14% are not.  The article also contains the map below (click to enlarge).
