* Defining "fluent" is subjective: What constitutes fluency? Is it being able to hold a conversation, read literature, or something else entirely?
* Data collection is difficult: There are many different surveys and estimates, but none are universally accepted as completely accurate.
* French is spoken in many countries: It's an official language in 29 countries, and people have different levels of proficiency across those regions.
Here are some general estimates:
* Native speakers: Around 250-300 million people worldwide have French as their native language.
* Total speakers: Including non-native speakers, estimates range from 300 million to 700 million.
However, these numbers should be considered approximate.
