I'm not sure on the exact sizes but I think its something along the lines of:
Biggest:
CDE and EMD
Policy
Middle:
Management
Environmental
Smallest:
Biostats
SBS
My advice: Apply where you belong and you have a better chance of being accepted than trying to play games with applying to concentrations just because of their size and the effect you think that will have on you getting in.
