Yep, some more awareness to different countries ways of dividing areas , cities and such.
E.G. I come from Denmark , Copenhagen. But I could also say Denmark, Sealand, Copenhagen area, Rødovre which has its own zip code but it is not very big geographic area I only have to move a few km to get out of this area. People might want to write what region they live in or what island they live on or the region they live in. So poepl can search on country and/or city/area or what ever they would like to search on.
Others from Denmark might write it like this
Denmark, west Sealand, Kalundborg here Kalundborg is the city and west sealand is the area or region.
Denmark, Læsø (a island in the middel of nowhere)
Denmark, Jutland, Middel Jutland, Århus
My sugestion is
**This could be anything e.g. I do not officially live in Copenhagen but I am so close it called Stor København (Big Copenhagen) meaning Copenhagen and the suburbs. Or people could mention what island they live on or
