Just throwing this one out there.
Data comes from the first destinations surveys of the respective years, from the Universities Statistical Record in 1991 and by HESA in 2010.
I'd like to include the types of occupation, but the economy was so different in structure there's no way I can do it meaningfully.
But we can do some small comparisons - in 1991, 13.5% of working first degree graduates went into science or engineering R&D. Last year it was 3.5%. In 1991, 17.1% of those employed went into financial roles (and that's not even counting management consultants). Last year - 7.5%. The proportions going into law and into health, education and social care (the latter three combined together into one mammoth category in 1991) are almost exactly the same, on the other hand. In 1991, there was no formal measurement of those going into computing and IT. It wasn't significant enough (although some did go in).
How things change.
