Rough approximation using only the top 100 users. Only a very few of them have filled the gender parameter, so, it is not a good approximation:

• /English Wikipedia: 1 woman per ~9 men
• /French Wikipedia: 0 women

    • Yep, nobody in the top 100 is defined as "female" : ) (but obviously there are some of them). Using top 10,000 I got better results. emijrp (talk) 01:09, 16 March 2011 (UTC)

Global digital divide, minorities Language gap Low language presence on the Internet

Language shapes our world. Every language is a different way to understand the universe. There are between 5000 and 10000 languages in the world (see Lists of languages for detailed lists) but only 279 Wikipedias (2.79–5.58%). So biased.

• How many people do not understand any Wikipedia?
