Africa: 400,000 people out of 1.1 billion get fluorides in there water.
Asia: close to none in China (didn't find any hard numbers), none in India, less than 1% in Japan. Only Malaysia is doing it at any resonable scale.
Europe: 2% of the population get it, roughly 14 million people with 10.5 million of those being in the UK and Ireland.
So that leaves North America, with the exception of Mexico which jas high natural fluoride levels and fluorides salt, Australia and Latin America.
Going by these numbers, the majority of people get fluoride through different means from drinking water. Afroca of cpurse has a lot of other issues regarding drinking water, starting with the exostince of clean drinking water itself.
You left out Australia 70%, New Zealand 60%, Brazil 41%, Chile 70% etc.
Japan, China, India, and much of Europe have many areas with natural levels of fluoride in the water near or even above the recommended level. Which seriously distort their numbers as proponents of adding fluoride to water supplies don’t want to increase it arbitrarily only to safe and effective levels.
China has some really interesting data as in one location removing fluoride quickly resulted in “the incidence of dental caries among 4-year-old children had increased by 62%.”
Asia: close to none in China (didn't find any hard numbers), none in India, less than 1% in Japan. Only Malaysia is doing it at any resonable scale.
Europe: 2% of the population get it, roughly 14 million people with 10.5 million of those being in the UK and Ireland.

So techinicalls you are correct, overall much less so.
