If you eat a lot of data it leaves you feeling hungry



After looking at some data suggesting that in at least one case, overall staffing at a university was overwhelmingly non-academic two questions arose: 1) What do they all do?  2) What proportion would be appropriate?  The data here (which has been partially discussed here) has some answers.

Page 38 of  the Equality in Higher Education: Statistical Report 2012, Part 1 Staff classifies non-academic staff into groups. Within the classifications of the data, non-academics in a university fill these sorts of roles:

Laboratory, engineering, building, IT and medical technicians (including nurses); Student welfare workers, careers advisors, vocational training instructors, personnel and planning officers; artistic, media, public relations, marketing and sports occupations, library assistants, clerks and general administrative assistants; Secretaries, typists, receptionists and telephonists; chefs, gardeners, electrical and construction trades, mechanical fitters and printers; Caretakers, residential wardens, sports and leisure attendants, nursery nurses and care occupations; Retail and customer service occupations; Drivers, maintenance supervisors and plant operatives; Cleaners, catering assistants, security officers, porters and maintenance workers.

There. That is what they do, at least in broad categories. Question 1 answered.

Is there anything to help with the question 2? Yes. Consider page 19 of the report. It shows that the proportion of academic staff in UK HEIs has grown over the last ten years. This is a good trend. 

Why?

It is good, because as important as chefs, gardeners, and drivers are, people do not pay to go to university to eat, look at grass, or drive stuff around. They are unlikely to go to a university where they can’t eat, where the landscape looks like a tip (a dump for Americans), and everything stays in the loading dock, so, yes, these roles are important, but not the purpose of the organisation. Students and their families do not envision “Operations Support Officers in the Student Experience Team” when they sign up to ~£30k of debt.  What they want are highly qualified experts in their fields who can teach. So, the trend is encouraging.

The growth has been slow, from 44.4% to 47.5% over roughly a decade but this is positive change. Professional and support staff is still the majority and this sector average seems reasonably healthy. 

What about the variance? You may have heard about the statistician who drowned in a river with an average depth of 3 feet.

Alas, this information is missing. Like all statistical studies, those 222 pages make you realise that one bit of information you want has been left out. The standard deviation is missing. Individual institution data is absent so you can’t compute it yourself. However, it is clear that within a sector averaging 47.5% academic staff, any institution with 17-34% academic staff is a long way from the norm.

What about the underlying mechanism producing the change? Is the change because all the cleaners are being let go and replaced by an external contractor? Are institutions focusing (albeit slowly) on their teaching and research missions, and hiring more academic staff and using the others more efficiently? I don’t think anyone knows. 

That is the bad thing about data, it always leaves you hungrier for more. Good thing brains don’t get fat because I have been eating data like a pig.
