- The European Union is a supranational union composed of 28 member states. The combined total English-speaking population (2012) is 256,876,220 (out of a total population of 500,000,000, i.e. 51%) including 65,478,252 native speakers and 191,397,968 non-native speakers, and would be ranked 2nd if it were included. English native speakers amount to 13% of the whole Union population, while the percentage of people that speak English "well enough in order to be able to have a conversation", either as first (32%), second (11%) or third (3%) foreign language, was 38%.
- When taken from this list and added together, the total number of English speakers in the world adds up to around 1,200,000,000. Likewise, the total number of native English speakers adds up to around 350,000,000. This implies that there are approximately 850,000,000 people who speak English as an additional language.

- Statistics on second language speakers are inevitably not precise; partly because there is no widely agreed definition of second language speakers – there is no differentiation between countries where English is the lingua franca and those where it is not.

- For a credible source pertaining to this data, please see: The Times of India], . Their article explains the difference between the 350 million number mentioned in a previous version of this Wikipedia article and the current number:
“ "Wikipedia's India estimate of 350 million includes two categories – "English Speakers" and "English Users". The distinction between the Speakers and Users is that Users only know how to read English words while Speakers know how to read English, understand spoken English as well as form their own sentences to converse in English. The distinction becomes clear when you consider the China numbers. China has over 200 million users that can read English words but, as anyone can see on the streets of China, only handful of million who are English speakers." ”
- An analysis of the 2001 Census of India, published in 2010, concluded that approximately 86 million Indians reported English as their second language, and another 39 million reported it as their third language. No data was available whether these individuals were English speakers or users.

- Before mistakenly correcting the percentage again, please note that there are fewer people aged 5 years or more in any country than there are people in that country, because some people are toddlers or infants. In other words, no, the numbers will not automatically add up. 63.71% is what the cited source, text above Figure 7, a report from the 2000 census, really says. This multiplied by the 2010 census's total population over 5 produces the number in the chart. The 2010 number comes from Philippines in Figures, 2013, Chapter 5, Demography, table 5.1 or 5.6
- From mid-2009 to late 2013 this entry overstated the number of native speakers by roughly 100fold, and inflated the number of total speakers, on the alleged basis of material in "Philippines". Ethnologue. 1999-02-19. Retrieved 2013-10-16.. In fact, Ethnologue as of 24th December 2013 simply repeats the number of native speakers, 20,000, reported in Crystal 2003, on the basis of an old (pre-1995) census, and does not address total speakers at all. This attempt to correct these errors in turn perpetrates both error and original research, by applying the old percentages listed above, 63.71% of people over 5 as total speakers in 2000, and .04% of people as native speakers in 1995, to the 2010 totals from Philippines in Figures, 2013, Chapter 5, Demography, tables 5.1 and 5.6. Andrew Gonzalez passed away in 2006; someone else's attention to the 2010 census figures, which appear not to be online and may not have been printed yet in adequate detail, is needed to produce reliable, more or less current, numbers.
