KDBN/WNNX PPM

I have a question about the latest ratings for FM9.3 in D/FW vs. 100.5 in Atlanta. They are both home of The Reguolar Guys and are for the most part identical formats... My question is why does WNNX have a cume of 423,600 and a 1.9 while KDBN has a cume of 408,800 and only a 0.4???

Cume is a number based on the population 6+ of the market. Dallas is a bigger market than Atlanta. But the 1.9 and 0.4 are share numbers... only indirectly related to cume.

Arbitron measures only Cume and Time Spent Listening. That is, the meter detects what stations the metered panelist hears, and it also records how long each is listened to.

The tabulated data allows the derivation or calculation of rating, share and AQH persons, which all come from the same source.

Share is a percentage of those listening to radio. To get a high share, you need a good cume and a good TSL. In the case of the show you mention, we don't know the TSL. But we know that the station gets a lower percentage of the population to cume it (listed as cume rating) in Dallas. So, everything else being equal, it has to get a lower share. My assumption is that part of the difference is a lower cume rating in Dallas, but it's also apparent that the show does not get the TSL in the Dallas market it gets in Atlanta.

So in Dallas, there was a lower cume as a percentage of the population, and lower TSL. Result: lower share.
