The fact that this only represents mother tongues makes it entirely useless of getting any real picture. In many countries, germany included, english being tought as early as grade school. For me personally and quite a few people i know, english is used 50% or more over the day due to our occupation. I doubt any of the chinese languages are picked up as secondary languages by anything remotely approaching the amount of secondary learners english has. (Consider for example that english is so pervasive and wide-spread in india that india has de-facto its own dialect of english, much like various places in the us or australia.)
