The following points are worth making. First, data on minerals, copyright, software and
R&D are taken from official sources. As mentioned above, preliminary work suggests
an undercounting of copyright spending. Second, data on workplace training are taken
from successive waves of an official government survey, weighted using ONS sampling
weights. Once again one might worry that such data are subject to biases and the like but
this does look like the best source currently available.
