Biggest French-Speaking Cities

Sorry to be a bore, but most of these cities listed don't speak French as a mother tongue. Kinshasa for instance. Barely nobody in that city speaks French as a native language. They speak native tribal languages that existed thousands of years before the French arrived, including Kituba, Swahili, Lingala and Tshiluba.

French is merely an "official" language of the Democratic Republic of the Congo. That doesn't mean people speak it natively, or even speak it at all.

Same goes for Abidjan, located in Ivory Coast, where the vast majority of people speak native tribal languages, but where roughly 30% of people have learned French as a 2nd language, due to the fact that it is a designated "official" language of Ivory Coast.

Official language doesn't mean they speak it.

Fun fact, the United Kingdom doesn't even have an official language, yet 95% of people speak English natively.

Right - I really wonder how these were determined by whoever posted them on whatever Wikipedia site. Some where French is an official language (e.g. Port au Prince) don't appear, which makes it seem like someone has tried to account for what Haz says. But then there are some inclusions that really make you wonder. There's no way that there are more French speakers than Malagasy speakers in Tana.
