If Malaysia has 27 million population, then it is about 3.7% was "drained away". If out of 27 million population,  14 million are aged between 21 to 55, then it is about 7.1% was "drained away". Interestingly, most of the "drained away" were Chinese.

What left in the system mainly are the "brain from the drain" - read here.
