How is Mandarin Chinese the most popular language spoken in world?

It's not entirely accurate to say Mandarin Chinese is the "most popular" language spoken in the world. While it's true that Mandarin Chinese has the largest number of native speakers, there are other ways to measure language popularity:

* Number of speakers: Mandarin Chinese is estimated to have over 1 billion native speakers, making it the most spoken language based on this metric.

* Global reach: English is the most widely spoken language globally, used by over 1.5 billion people as either a first or second language.

* Official languages: English is the official language of many countries, while Mandarin Chinese is primarily spoken in China and a few other countries.

* Internet usage: English dominates the internet, with the majority of websites and online content being in English.

Therefore, while Mandarin Chinese has the most native speakers, it doesn't necessarily qualify as the "most popular" language globally. It depends on how you define "popularity."
