To account for the multidisciplinary nature of research, and impact, and the fact that research could occur in one FoR and impact be realised in different FoRs, institutions where asked to list additional FoR codes for the impact study.
The data displays the frequency with which additional FoR codes were listed for each primary FoR code. For example, the most frequently listed FoR code for 06 Biological Sciences was 16 Environmental Sciences.
