This chart means that the governerate with a higher percentage of university graduates is more likely to vote no in the last referendum.

You can access referendum results here.

UPDATE: I uploaded an excel file with data from referendum and numbers of university graduates from CAPMAS. The data from CAPMAS is from 2006.

This is just a dump of one correlation found. I am trying to look for other interesting bits in this data.

Professor Tarek Masoud found a weaker correlation "between illiteracy and the likelihood that people voted yes on the constitutional referendum."
