Can I get info (say a map) on the cost of living in different areas?

I was just doing some thinking about where I might want to be, things like that. I was wondering how much it might cost to live in one area, versus where I am now, and so on. I’m sort of struggling in an expensive area. It would be very helpful if there was a map that showed what the cost of living was in different areas.

Now, there are different aspects of the cost of living. Property value is a huge one, and just that would help. Income levels might be relevant. I’m sure there are some overall cost-of-living indices that are computed. Anyway, is there any place where you can browse a map that is simply color-coded according to costs, something like that? I realize it might depend on whether things are averaged out by county, or neighborhood, or what.

I think the Economist publishes a yearly survey on the cost of living in different cities all over the world, you might want to check that out.

That’s an awesome reference. Does anyone know of anything similar that compares at the city level nationwide? I ask because I currently live in the NYC area, but come from Upstate NY, where life is relatively cheap (at least compared to here).
