As described in this Github issue:
While describing the particular geographic area(s) that a grant benefit is very useful, some additional data might help classify and help users understand the scope to which this grant applies.
International - a grant applicable to the world/global
National - a grant applicable to a whole country
Regional - a sub region of a country (e.g., London in UK context)
District - (local authority in UK context)
Local - (ward level)
A focus would be to properly describe the above (proposed) codes, without slipping into UK specifics
This, however, brings us again to the question of codelists.
Should this field help to add more context to beneficiary location?
