Overseas Chinese

I recently came across this interesting article on overseas Chinese:

http://en.wikipedia.org/wiki/Overseas_Chinese

A question arose regarding the population numbers used in the article, so someone clarified it here:

http://en.wikipedia.org/wiki/Talk:Overseas_Chinese#The_numbers_are_from.3F

Keeping in mind that these numbers are from a couple of years ago, that they're approximate, and that the actual figures are always changing, it is still interesting to note that if we for argument's sake say that there are now about 65 million Chinese outside of mainland China, and that there are about 1.3 billion Chinese inside mainland China (see this page, top left corner), that means that only about 5% of all the Chinese in the world are outside mainland China.
