This question refers to 4 markets: Los Angeles, Riverside-San Bernardino, Washington, and Baltimore, so hopefully this forum is the best one for me to learn this aspect of Arbitron Radio Metro Markets.
This flows from these threads on 2 separate forums.

I believe that I have learned these things so far
1. The fairly new Arbitron policy is that, in the publicly released 12+ numbers, Arbitron no longer lists any non-subscribing stations, whether in-market or out-of-market.
2. Even a subscribing station will only be listed for the specific market(s) for which it is considered “subscribed” by Arbitron.
3. Many stations are under group contracts or agreements for various markets.
Have I got it right so far?
Then, these situations are what I find so counter-intuitive.
No commercial Baltimore station subscribes to the Washington, DC book, and vice-versa. The only 2 stations listed in the public ratings in both markets are WAMU-FM and WGTS-FM, which Huff explains “Those two stations are non-commercial and are licensed to show publicly in any book by virtue of a national licensing arrangement with the Radio Research Council”.
Huff also informs that “There is significant overlap of DC stations in Baltimore, with nearly a dozen Washington stations pulling at least a 1.0 share on average. Far fewer Baltimore stations show in the Washington book, with much lower listening levels.”
Central Baltimore to Central Washington is roughly 36 miles as the crow flies, and about 39 miles driving.
They are very close, the listening overlaps quite a bit, and yet not one commercial station in either market subscribes in the other market.
Contrast this situation with Southern California.
Riverside is closer to Los Angeles than is San Bernardino, and is about 49 miles as the crow flies, and approximately 59 miles driving. So, best case, at least 10 miles further apart than Washington is from Baltimore.
But it is more different than that. These 2 SoCal markets are considered so separate for Radio purposes that they have a No-Man’s-Land between them.
What DavidEduardo has described as “the foothill area of San Bernardino County from the LA County border through Fontana and Rancho Cucamonga and to Rialto”, which Arbitron labels San Bernardino County West Outer, is part of no market at all, an orphan, a No-Man’s-Land, and which David has estimated has about 800,000 persons. This has to be by far the most populated urban/suburban area in the USA which is excluded from any Arbitron Radio Market; I do not believe there is any area of similar density of even one-quarter the population which is not a part of any Arbitron Radio Market -- truly one-of-a-kind.
And yet, there are 11 stations (excluding XEWW-AM Rosarito) which are publicly released in both markets, which means these stations are subscribed for both markets. DavidEduardo has indicated that it is most likely because those stations are part of group contracts, such that these 11 stations are considered by Arbitron to be “subscribed” in both markets (David, I am paraphrasing here, so please let me know if it’s not 100% what you have meant).
So, here’s what I cannot make sense of.
Washington and Baltimore: closer to each other, relatively flat terrain between them, more signal overlap, some stations getting a sizeable share in the other market, the market boundary is adjacent for many miles, but not one commercial station is considered “subscribed” by Arbitron for the other market, and thus none are shown in the publicly released ratings.
Los Angeles and Riverside-San Bernardino: farther apart by about 10 miles, more topography interference, supposedly less signal overlap, not adjacent but separated by a No-Man’s-Land, but 11 stations are considered “subscribed” by Arbitron for the other market, and thus all 11 are shown in the publicly released ratings in both markets.
The only possible explanation that I can dream up is that NONE of the commercial stations in either the Washington or Baltimore markets belongs to an ownership group such that by a corporate contract they would be automatically shown in the publicly released ratings in both markets, as seems to be the case in the 2 Southern California markets.
Is this actually possible?
Or what do I still not understand?
