There are 4 concentrations in the department. I saw some from health services and maybe bioethics? but not from health and public policy. As far as I know those haven't gone out yet, because they haven't decided the funding offers. I had to ask the office how it works since I won't be getting a normal admission letter since I deferred, and they said it would be similar but it wouldn't be until closer to the end of the month.
Last year there were 12 people admitted across the department: 2 in bioethics, 2 in economics, 4 in health services, and 4 in health and public policy + 1 who deferred from the previous year, so 13 total. I don't know how many it will be total if they are admitting fewer and which concentrations will have fewer students or if it will be all.
