There are ISO standard codes for countries: US, CA, GB, AU, etc.  These each
fit into a fixed-width CHAR(2) field.

I would use a VARCHAR of some large size and map it into structured fields
using views. Each view is built with
   WHERE country_code = 'xx'
for the matching 'xx' in the ISO standard. This will allow you to search in
a structured manner, provided you have the country code.
