The 11 confederate states plus the three border states that, at least in part, supported the confederacy or divided on the issue had a total of 116 colleges between them. It could also be noted that at the time of the war there were 34 states. From this we may observe that:
1. The 11 CSA states made up 32% of the total number of states yet had 36% of the colleges.
2. The non-border yankee states made up 59% of the total number of states yet had only 50% of the colleges.
Put another way, the south had a disproportionately higher number of colleges to its total number of states than the north, which ran a disproportionate deficit.
Border States were not part of the Slaver political empire and did not share its cultural void. They remained part of the Union.
Again I do not consider the educational potential the same from one college to another. Neither do authorities on this issue.
