Peterson's, and Collegeview: Where do they get their information?

NOTE: Thanks to commenter below-I should have pointed out, there are more than 1100 faculty at WCC, and therefore the info given to Collegeview must refer only to full-timers. So, why?  Who left out the majority of the faculty? More later.

Ok here's another, and my query:

I am an adjunct prof at Westchester Community College (WCC) and elsewhere. Your faculty numbers for WCC are not correct. There are more than 1100 faculty at WCC, but your numbers indicate a total of only 174. Where did you get your numbers from? This is a serious difficulty. I am sure that the WCC Office of Institutional Research and Planning can help you correct this. 

I hope other people are looking at their colleges. On these types of sites and, by the way, at the Bureau of Labor Statistics—don't get me started, I have to grade a zillion exams!—there are strong hints of very dicey reporting practices, for many colleges and institutions, not just WCC

Do you know what your institutions are telling the public, and state and federal government?
