This is also needed in the Search section. I can see the request came from the United States, the City Region is Middletown. There are many towns/cities caled Middletown across the US, and without the aid of a placement on a map, you have no way of knowing.
Maybe it should be a 3 way break down:
Country > State/Region > City
I can see how this would be very useful for ecommerce sites who are targeting specific states/regions, so they could use the granularity to be able to list them all by state.
Maybe add a "View Search Results on Map view" would also be handy here, so you can visualize your own sort of cluster maps based on your search criteria.
