Last summer there was a comp.graphics discussion of geographical databases.
One bottleneck was datasets.
I read in the San Jose Mercury News that the Census Bureau has a hierarchical
geographical database of 106M households in the US and will be selling
parts of it.   It is in something called the TIGER format.

(The Bureau cant release the raw it is collecting from each household for
many decades for reasons of privacy.  It aggregates the results over
several thousand households in the report it releases at the end of the year.)
