I think you can get a very rough sense of possible changes by comparing the results from different years (as in the first two graphs in the post), but given the difficulties in interpreting these differences I would be wary of presenting these as % changes. Aside from possible differences in the sample across different years, changing categories for causes would also obviously distort things (we start with a fairly strong presumption against changing categories for this reason, but in some cases, the development of Mental Health as a field being one, it’s unavoidable).
