How difficult is it to get into Weinberg CAS compared to other schools of NU?

I am interested in majoring economics at WCAS and am curious how difficult it is to get into the college.
I have done some research and found out that the early decision admit rate for Northwestern U is a little above 30 percent, but I am curious if that acceptance rate reflects the WCAS acceptance with only slight difference or if that for WCAS is considerably lower or higher, like Cornell whose CAS has a lower admit rate than its overall admit rate.
