Facebook API: How can I get geo information from a location?

Question

Facebook

The Facebook API returns location data for a user in the form:
array (
  'name' => 'New York, New York',
  'id' => 108424279189115,
),
The link graph.facebook.com/108424279189115 provides a profile of the city of New York. As far as we know, this information is added by the user themselves, and not by Facebook employees.
Questions:
1) How can you use these data, and in particular id = 108424279189115, to get the data that this is USA / NY / New York ...? To what extent can this data be trusted and are there alternative sources for obtaining this data?
2) Is it possible to download the database from this data somewhere?
