My “facts” are taken from different sources all over the Internet. Many of them may be slightly outdated, because my sources were published in different years and all of these statistics change all the time. But I think that many of them are changing for the benefit of the English language.
English is the native language for about 380 millions of people.
English has the richest vocabulary compared to all the other languages in the world. There are 500,000 words in the Oxford English Dictionary, and there are about similar number of words, mainly technical terms still uncatalogued.
Three-quarters of all e-mails in the world are written in English.
More that half of scientific and technical periodicals are in English.
About 80% of data stored on computers all over the world is in English.
About 89% of schoolchildren in the European Union are learning English as a foreign language.
I searched for quite long on the Internet for information about the number of English learners in the world and I didn’t find the amount of current ones. The most frequently cited and reliable information was published on the British Council website. According to this information over 1 billion people were learning English in 2000. It is so outdated. I find some predictions that in last decade this number should have been doubled. So it is possible that there are 2 billion people learning English now. But this is only a presumption and I found other theories that said that 2 billion people will be learning English in 2020.
So there is a lot of information on English on the Internet, but not enough (or the information is too buried on the web).
