Where are your users?

I saw this graphic on Gizmodo and it made me think:
Manhattan’s Population By Day vs Manhattan’s Population By Night

I thought that it would b very interesting to see library user populations in this kind of data visualization. How about plotting the zip or postal codes of your library cardholders on to a map of your community? Does it relate to your branch structure, or not? Do you see differences in daytime commuter and home use? How about plotting local schools into the mix . . .?
This is apparently not too hard using mashups with Google Maps.
Interesting, eh?

    I rather suspect senior library administrators already have a pretty shrewed idea of where the holes are in their branch networks. If they did this type of analysis would they be willing to release the information so that those of us stuck in library deserts could use it to lobby for better service?

    Interesting, and much less grizzly than the interactive New York homicide map (although it is a fascinating application) http://projects.nytimes.com/crime/homicides/map
