All I can find is 2017.
Common Data Sets are published around March. There is a website where institutions upload financial and enrolment information used by Moody’s and other bond issuers. In the past the public could see it. This year the site layout has changed or that information is no longer available to the public. 
@TomSrOfBoston I was wondering when you would post that info… too bad it is not public anymore.
Thanks @TomSrOfBoston Does that mean it will not be public at all, or will it eventually be on NEU’s website?
Most of that information will be in the CDS for 2018 around March. I will continue to snoop for it though. 
The information was actually posted here in the past by someone else. Maybe s/he will have access to it for 2018.
The 2018 Common Data Set has been published!
https://provost.northeastern.edu/uds/facts/common-data-set/
The Fall 2018 acceptance rate was 19%. The yield was 23%.
The ED acceptance rate was 41%.
The entering class size was 2746 students. It is just shy of the traditional target of 2800 and was likely kept low due to the over enrolment in 2017.
The freshman retention rate was 97% and 6 year graduation rate was 88%.
The transfer acceptance rate was 31% and transfer yield was 41%.
Total full time enrolment undergraduate and graduate was 26,290 students.
Thanks @TomSrOfBoston. I just looked the other day and was wondering if it was ever going to be published!
