There are several hundred languages in the People's Republic of China. The predominant language is Standard Chinese, which is based on Beijingese, but there are hundreds of related Chinese languages, collectively known as Hanyu (simplified Chinese: 汉语; traditional Chinese: 漢語; pinyin: Hànyǔ, 'Han language'), that are spoken by 92% of the population. The Chinese (or 'Sinitic') languages are typically divided into seven major language groups, and their study is a distinct academic discipline. They differ as much from each other morphologically and phonetically as do English, German and Danish, but speakers of different Chinese languages are taught to write in Mandarin (written vernacular Mandarin) at school and often do to communicate with speakers of other Chinese languages. This does not mean non-Mandarin Sinitic languages do not have vernacular written forms however (see written Cantonese). There are in addition approximately 300 minority languages spoken by the remaining 8% of the population of China. The ones with greatest state support are Mongolian, Tibetan, Uyghur and Zhuang.
According to the 2010 edition of Nationalencyklopedin, 955 million out of China's then-population of 1.34 billion spoke some variety of Mandarin Chinese as their first language, accounting for 71% of the country's population. According to the 2019 edition of Ethnologue, 904 million people in China spoke some variety of Mandarin as their first language in 2017.
