EPSRC classifies the research it supports by industrial relevance/sector. A list of industrial sectors and their meanings are available.
Please note that the assignment of a sector to a grant indicates that the sector may apply in whole or in part to the research activity of that grant. This means that the values of grants within a classification should not be totalled to find the total investment in that area or to compare investment between areas of research. The value shown for each grant is always the total awarded, not the proportion attributed to the individual industrial sector.
