Well allow me to elaborate on this one. Providence according to the Census Bureau is part of Boston's CSA but Providence has its own MSA as well. Not only that it too has its own airport (Theodore Green) and media market. And places like Worcester, MA and Manchester, NH are part of Boston's CSA but they have their own MSA's as well and their own airports to top it off. And if Providence, Worcester, and Manchester didn't have their own airports then Logan would of been a sardine can.

Indeed. We all know that won't happen but there are many CSA's with multiple airports, even in Ohio (Cleveland Hopkins and CAK). Though I do agree there would be a major benefit if RTA and SORTA teamed up for some sort of Southwest Ohio rail-line between Dayton, Middletown, Hamilton, and Cincinnati. That certainly makes sense. As you know Baltimore-Washington is not a proper MSA. Instead it's a CSA, and both the cities still have their own metro areas. Of course Baltimore and Washington do share an airport together, however Washington has two airports for itself. Dulles and Ronald Reagan. And not only that both the cities do have their own media markets and economic identities.

Will I doubt it will get any of that.

And that is exactly what I had in mind. That could be the most likely outcome. You know if Los Angeles and San Diego were to go that length then they could most likely be a CSA and not an MSA. And you are more likely to see the metro areas of Hartford, CT and Springfield, MA merge together than you are of Cincinnati and Dayton together. The same could be said of Columbus, GA and Auburn, AL. Their metro areas are much closer than Cincinnati and Dayton's are.

You can also find the data here if you know how to work it. https://onthemap.ces.census.gov/ Also many people at Ford in Sharonville where I work lives in the Dayton metro. 10.7% of Dayton workers(33,388) work in the Cincinnati Metro. 11.2% of Dayton workers(36,861) live in the Cincinnati Metro. 21.9% is the exchange rate of the two metros involving 70249 workers. 2014 data I did not use all workers such as farming or the number would be greater. I used primary workers. Will somebody certainly managed to scoop up some actual statistics, but as stands out only a small percentage of such residents make such commutes.

About commuting patterns, most people in the Cincinnati MSA don't commute to anywhere in the Dayton MSA, or vice versa. And as it stands out only a certain part of the Cincinnati MSA commute to the Dayton area, namely the West Chester-Liberty Township area. You see I live in the Cincinnati MSA, and I certainly do not commute to Dayton, nor do any people I know who live in my vicinity. Also about the article you cited, it really seems to be based on pure speculation because I found numerous articles dating back a several years ago, and it said it could happen in the next census, but it didn't actually happen, so again it all seems to be based on pure speculation. There could also but speculation that the metro areas of Los Angeles and San Diego could merge together, and the chances of Cincinnati and Dayton's metro areas coming together are as likely as that. Let me cite an article: *http://www.bizjournals.com/cincinnati/stories/1998/11/09/story3.html from 1998 and expected to happen in the 2000 census, but didn't.

Will let's look at Cleveland-Akron. That's a CSA, and yet Cleveland and Akron are closer to each other than Cincinnati and Dayton are. Also Dayton does possess it's own economic identity. It has it's own airport and media market, and that can be comparable to Washington-Baltimore.

Um, that is a popular article and not an official document, and I suspect Cincinnati-Dayton is more likely to become a CSA than a proper MSA, which would be comparable to Washington-Baltimore.

If Cincinnati and Dayton do merge it would most likely be a Combined Statistical Area aka CSA and not an MSA. You see Dayton still possess it's own economic identity. It has it's own airport and media market, so Dayton will somehow always be separate from Cincinnati. Contrary to popular belief, Washington and Baltimore do not share the same metro area. They are still separate. Yes I know there's Baltimore-Washington Airport but Washington has two airports of its own. Dulles and Ronald Reagan. And both cities have their own media markets as well.
