It is a report from Ethnologue.
You can see the report here:
https://www.ethnologue.com/insights/ethnologue200/It is the 14th most spoken language in the world right now.
The report is for all countries in the world. Hausa, Yoruba and Igbo and other languages are also there. Visit the above link to search if the language that you are speaking is there, but I think just English, Pidgin, Hausa, Yorùbá and Igbo are there that is related to us.
I won't be surprised if foreigners start speaking Nigerian Pidgin. Pidgin sounds so sweet and is widely understood among Nigerians. It would be better if the federal government made Nigerian Pidgin an official language in Nigeria like other countries do, like China, India, and others that make their languages official to speak and write. It could also bring development to the country because people from other countries will learn pidgin and make communication with one another easier. and it will also make easier most especially people in rural areas or trades to communicate with anyone across the country.
