Cantonese is the language spoken by Canton people, Hong Kong people, people in Macau, and Chinese overseas. There were about 120,000,000 people using this language according to "Ethnologue: Languages of the World, Fifteenth edition".

According to Wikipedia, "The areas of China with the highest concentration of speakers are the provinces of Guangdong and (eastern) Guangxi and the regions of Hong Kong and Macau. There are also substantial Cantonese- and Taishanese-speaking minorities overseas in Southeast Asia, Canada, Australia, France, and the United States."

"Although Cantonese shares much vocabulary with Mandarin Chinese, the two languages are not mutually intelligible largely because of pronunciation and grammatical differences. Sentence structure, in particular the placement of the verb, sometimes differs between the two languages. The use of vocabulary in Cantonese also tends to have more historic roots. The most notable difference between Cantonese and Mandarin is how the spoken word is written..."
