This recent Bloomberg/Businessweek article notes that the number of women taking the GMAT exam from China, Taiwan, Vietnam and Thailand is now greater than men.  Last year, 57% of all examinees from Taiwan were women.  These Asian female applicants to MBA programs are likely the reason female enrollment in many programs has increased in recent years.  Ten years ago MBA programs generally had about 25% female enrollment, but now in many programs female enrollment accounts for over 30% of all students.
