* Nearly everyone in Chile speaks Spanish: It's the primary language used in everyday life, education, government, and media.
* There's no official census: Chile doesn't regularly conduct surveys solely focused on language usage.
* Indigenous languages: While Spanish is dominant, there are also indigenous languages spoken in Chile, such as Mapudungun and Aymara.
Therefore, it's safe to assume that the vast majority of Chileans speak Spanish, with a figure likely exceeding 95%.
