Newspaper circulation, education level and number of bookstores as a function of population would seem to be better indicators of literacy. I would certainly put Washington, D.C. above Miami, FL, in any comparison. Any survey that is missing Minnesota, and Minneapolis, in particular, is highly suspect. Minnesota ranks #1 in the U.S. with the highest average SAT score (1778). Think about that when deciding where to live, or raise a child.
