I'll go by this stat...
GMAT Registrations January-May 2007 106,571
GMAT Registrations January-May 2008 118,684
11.37% increase in GMAT registratins this year. I think that's the best proxy for the application increase.
Oh and another interesting stat. For all the talk of the US recession and layoffs on Wall Street leading to the surge in applicants. It's just not true. The real surge is coming from the same place it's been coming from the last few years.... international applicants.
Increase in US GMAT registrations (same time period as above) 4.88%
Increase in Intl GMAT registratiosn (same time period as above) 22.97%
As we all know, most of the MBA programs already have a higher proportion of international applicants than international students. With the top schools already pushing 40% international, I don't think the proportion of the student body that's international is going to increase. For that reason I think the competition among international applicants will be intense this year. For US applicants, despite all the talk about the effect of the recession, GMATs are only up 5%. So, while it will still probably be the toughest year for domestic applicants since 2002, it will be even tougher for international applicants.
