No and no.
I'll give a bit more information on the scale. There are 5 different shades of blue which represent the number of X in each country. From lightest to darkest, the shades roughly equate to...
- A few
- Up to around a dozen or so
- A few tens
- Many tens up to a couple of hundred
- Many hundreds to perhaps over 1,000
The white countries, as far as I can ascertain, have no examples, but it's entirely possible that any one of them may have 1 or 2, but not really more than that.
I did have trouble finding exact numbers as different sources were in disagreement, but within those broad classifications I think this is quite close.
