Roundabouts are rare to find in North America. You might come across some in Singapore and Hong Kong in Asia, maybe India, but those were former British Colonies, and traffic policy more or less copied the UK for as long as they could.
I think South Africa has roundabouts in the larger, built up cities, but again, that's more for them mirroring the UK's traffic policies for a long time.
Overall, the countries which have embraced roundabouts are either European countries, or the former colonies of European countries. North America has experimented with them, but doesn't quite get them, and Asia just doesn't like them, preferring to go with signalled junctions.
Africa isn't known for infrastructure....
South America will probably have them in the large cities of Rio, Sao Paulo, Santiago and Buenos Aires.
