Enrolments at Australian universities increased 56% in 2002-2015, but only 32% in STEM due to a crash of 23% in IT numbers.
Taken separately the sciences and engineering appear to fare better than average, with growth of 67% and 73%. However, this better than average performance is due entirely to overseas student enrolments. Take them out, and domestic student enrolments increased only by the university average of 56% in the sciences. In engineering the increase is well below, at 43%.
These figures and much more are contained in the report, STEM in Australia: The statistical patterns of university science and technology in the twenty-first century, the latest in a series by Dr Ian Dobson, commissioned by the ACDS.
