Whoever "itsMeItsMe" is is dead-on about this ratings sample. Horribly out-of-balance. On top of having over half the book based on those aged 55 and up, only 20% of the tabs came back from 25-44 year olds. Folks, that's 40% of the area's population barely accounted for. That meant that contemporary stations (pop, urban, HAC, even country, modern rock) were left fighting for half the sample they should've been represented by; and since Arbitron only got half of what they should've gotten from that portion of the population, whatever they got, they over-weighted. It was a crap shoot. A complete gamble. Less books had more influence.
If not Arbition, FREQDEV asks, then what? Well, I was never an advocate before of the once-a-year Nielsen approach Cumulus has embraced, but since this is a two-book average market, anyhow, you have to live with whatever numbers you get for a year, anyhow. So if Nielsen's going to do a better, more thorough job, I'd be all for it. Just my two cents.
And to dismiss the facts, FREQDEV, is to accept blissful ignorance, friend. If Arbitron does its job well, and thorougly, nobody'd have a beef, correct? If the 25-44 demo's in-tabs represented 40% of the diary, and the over-55 demo were fairly represnted based on their population weight in the market, it's hard to argue that the results would be the same.
