However, this language family is spoken by millions, especially in populous countries like Indonesia and the Philippines.
Step-by-step explanation:
The question asks about the percentage of the world's population that speaks languages belonging to the Austronesian language family. To answer this, we need to consider the global linguistic demographics. The Austronesian language family is a large and diverse group of languages spoken across the Pacific and in parts of Southeast Asia. This includes languages like Malay, Indonesian, Filipino, and Malagasy, as well as numerous other languages spoken in the Pacific Islands. However, there is no specific figure mentioned in the provided information that directly states the percentage of global speakers of the Austronesian languages. With over 6,000 languages worldwide and a large portion of them having a small number of speakers, the Austronesian language family, while widely dispersed, does not have a single language with over 50 million native speakers, based on the provided information. Still, the languages are spoken by millions of people, particularly in Indonesia and the Philippines, which are populous countries.
