My own estimate,about 400,000 singapoore citizens are not in SingapooWhat you talking about, aren't you an ex-Sporean
I know alot of ex-Sporeans who've voted with their feet: relatives, ex-classmates, friends,ex-colleagues.... I know alot of people who plan to leave & those who wish they could leave.
In terms of percentage,it is about 16%
It means that for the Philippines,there should be about 14 millions
The actual no of Pinos overseas is obviously less than that number!not to mention PRC(1.3 billions) and India(1.2 billions+)
