* Haitian Creole is the dominant language: Haitian Creole, a French-based creole language, is the primary language of the vast majority of Haitians. It's spoken by over 95% of the population.
* French is an official language: French is also an official language, mainly used in formal settings like government, education, and certain professional circles.
* Bilingualism is common: Many Haitians are bilingual in both Haitian Creole and French.
Therefore, while French is an official language, it's not widely spoken as a primary language. It's more accurate to say that a large portion of the population is bilingual in Haitian Creole and French.
To get a better idea of language use in Haiti, you could research studies conducted by organizations like UNESCO or the Haitian government.
