JohnLodge - It's not nonsensical to say that urban areas, cities, attract the young creative class. It's a known FACT.

Historically, and to this day, this is a major selling point OF cities. It's a place where people can get together, share ideas and become active. Of course, other factors are there, such as efficient use of space, entertainment, transportation hubs and convenience.

It's been well documented that young professionals seek out urban areas.

IN FACT, research has shown than most graduates, straight out of college, will chose WHERE they want to live, BEFORE they have a job. You pair that with the known fact of these young professionals preferring urban areas, and you get your support for why ad agencies in major cities may have a better chance of finding clients.

Michigan has been witnessing a "brain drain" for a while now, although exacerbated due to the poor economy. It's been documented in the Freep and Detnews that this is due to lack of jobs, and vibrant city centers. [[We all know Michigan does not support its cities, as evidenced by the large amount of failed cities)

Having a vibrant city attracts the ever so important, and attractive [[to employers) young professionals. This can help persuade businesses to move to the city where they are located. Where there are young and ambitious employees, there will be fresh new and exciting ideas. So, it is definitely possible that urban ad agencies have a better chance of attracting clients, due to having more young professionals employed.
