What is the sample size used in the Arbitron M 25-54 subcategory? 1/10,000 of that demographic? 1/25,000 ? 1/50,000 1/100,000 ? How minute, insignificant, and unreliable is this sample size?
A panel is supposed to be proportional on all the stratification variables it covers... in this cases, age cells, gender, ethnicity, county of residence in the metro, income levels, language preference among Hispanics, etc. The target sample for any cell in PPM should be around one meter for every thousand to 1500 persons in the universe
Why does Arbitron post 12 + cumulative ratings if they are so meaningless?
.]It is apparently good promotion for the product and increases awareness of the brand as THE sp.oóurce for ratings.
[./quote]Why would an advertiser not acknowledge that station A gets 625,000 listeners and station X gets 370,000 listeners. [/quote]
Advertisers don't acknowledge listeners. They simply buy the listeners in their core demo that the station offers if the price is right. Just like I go into a store with blue and gray pants, and only buy a blue one. I buy what I need.
[./quote]That is ridiculous . So a 55 y.o. M is irrelevant. 24 y.o \M irrelevant. The entire female gender irrelevant.

Most campaigns focus on delivery of 25-54 adults. Next comes 18-49 and 18-34, and the gender and ethnic subsets of each.
It's not uncommon to find campaigns aimed at 25-44 English dominant Hispanic Females in household with over $50 k annual income.
In other words, you fish where the fish are.
