Well, what do you consider to be an Anglophone country, anyways?

1. Areas where English per se is the native language of a majority of the population? (USA, UK, most of Canada, Australia, Aotearoa, Ireland, many territories or dependencies of the aforementioned)
2. Areas where an English-derived creole is the native language of a majority of the population, and where English per se is the language of prestige? (mainly Caribbean islands, including the former socialist state Grenada, where their English proficiency was a major reason for their priority targeting by the US)
3. Areas where English is an official or administrative language that is not the native language of most of the population? (India, Philippines, PNG, Fiji, much of Africa and the Pacific etc — South Africa stands out for its high English proficiency within this group)
4. Areas where English does not have official status, but where the people of the country are nevertheless highly proficient in English? (Nordic region, Benelux, Germany, Austria, Portugal, Croatia, Greece…)
