Gender Ratio

One of my foreigner colleagues was asking me on the demographics of the people in the company. The topic naturally progressed to the gender ratio of Singapore. He mentioned that he thought there are more working females in Singapore which I concurred based casually on the fact that I seemed to often see more female passengers in the office lifts.

He thought the female ratio is higher as the males may have left Singapore to skip NS as some of his friends in Australia does. This may be true but I was not so sure it is the main reason as I believe there are not many such "escape" cases. I was wondering whether it could be due to work mobility as in males may be more willing to relocate for work.

Digging further, I went to look for the official statistics as pasted below.



As we can see, at least during the productive working years, there are many more females than males in Singapore.

Under natural birth rate, the ratio of males to female should be higher though with increase in ages, the ratio will creep lower as female has higher life expectancy. Looking at the statistics, during birth, there are more males to female. However the gender ratio turned somewhat dramatically for population between 25-39. I am guessing that it may be due to differences in work mobility for the genders. This is interesting, maybe such numbers are/can be looked if we need to draft some action plans for social issues.
