Hard to give a good suggestion, but for others to suggest something correct, please let me give explanations abou thow this is calculated: -for each language supported in Debian, I included two numbers in the reference file (attached): - the number of language speakers, according to Ethnologue (www.ethnologue.com) - the "estimated" number of language speakers, calculated from an estimation taken from various sources (including translators) "speakers" mean "people with the given language as a "mother tongue", ie a language they learnt in their childhood The second number is often a correction of the first one, when the first one is obviously underestimated. For instance, take a few examples: -Dutch has 17M, according to Ethnologue. According to Frans, and indeed everybody with a brain, Dutch can be understood by at least the entire population of the Netherlands (the number of people who don't have Dutch as mother tongue and are Dutch is easily compensated by those who have Dutch as mother tongue and aren't Dutch. As a consequence, the number becomes 21M, which is approximately the population of the Netherlands plus the Dutch speaking part of Belgium, if I'm correct (unverified as of now ;-)) -German is listed for 95M as first number, which we corrected to 101M, which is roughly the cumulated pop of Germany/Austria/Switzerland (german speaking part) -There are many special cases, such as avoiding to count Catalan people for both Catalan and Spanish So, the second number tries to be a good representation of "people who are comfortable with the said language" and also avoid counting people for two languages (which explains why English has only 309M so roughly the number of inhabitants of English speaking countries, without citizens of India where other languages are the real street language while English is among the official languages, who are counted for Hindi/Gujarati/Tamil/etc. I would say something like "We estimate that 57% of the world population will be able to install Debian in a language they're familiar with since their childhood".
