An AdWords campaign can be targeted as broadly or precisely as required.
Specify the language of the adverts in the campaign. Specify the country or countries that will see the adverts (all countries is an option).
An advert in a specified language targeted to a specified country, or collection of countries, will be shown to searchers who:
Within a specified country it is possible to refine the target audience to a region or city. But for this to work, the IP address of the searcher must be registered to that region or city. Since most Internet Service Providers work on a national level, it is unlikely that the assigned IP address will reflect the true location of the user.
The solution is to create two campaigns. One that is targeted locally and another that is targeted nationally but contains local location keywords.
This allows you to take the concept of local targeting even further. There are three options:
Again a national campaign with localised keywords should also be set up to overcome the limitations of assigned IP addresses.
