Only the "Beauty Contest" rankers of ages 6-plus are allowed to be publicly posted. Those figures, though interesting to see, are absolutely worthless when it comes to finding the wheres and whatfors in numbers that mean anything.
Despite how people try. They would be called "wrong" because buyers of the research and those that put the research to good use ignore the "overall numbers" to narrow it down to the "money demos", as David Eduardo has explained in thread after thread, accurately.
Now, Neilsen / Arbitron has gotten tighter in that they only publish stations who subscribe to the research. Anyone else, a #1 station or not that doesn't subscribe to the ratings get's listed only in subsriber's books and not for public use. The subscribing stations are sworn to not share the "inside" of what those numbers show...hence the expense of the book to subscribers. Those numbers, to the public, never see the light of day, lest a subscriber face difficulties in sharing any information. Same with ad agencies which buy the book.
There is nothing, actually, that can be extrapolated from the overall numbers 6-plus except an overall ranker. The audience makeup could be completely different with the demos reported.
