Transfer between institutions and gender imbalance (aka missing females)

Just as many Singaporean poly students gripe about the admissions discrimination against them by the local universities (notably NUS), in the US both elite public and private universities are making it harder for community college students to transfer in for their junior and senior years.

Loiseaurebelle wondered about a gender imbalance among Singaporean students here. While I can't comment much about the undergrads, at the grad level I would think that family dissuasion and concerns over being over-aged/over-educated and thus chances of finding a spouse are major factors. I see the same phenomena among peers from the other East Asian countries - notably China, Korea, Japan, Taiwan, Malaysia and Indonesia.

It is slightly more even for the Europeans.
