ESRI, the company that is well known for their geo-location and mapping products, has queitly lunched an iPhone app that lets users retrive demographics facts about locations in the United States.
While the app could have some interesting business uses for profesionals, anyone can find themselves comparing their own neighborhood against other neighborhoods or the entire US.
I installed it on my iPhone today and I have been playing with it for a little bit. I think you may find it interesting also.
You can read more about the app at the Business Analyst Blog or download it directly from the Apple app store.
