EPSRC classifies the research it supports by socio-economic theme. This taxonomy has been used to classify all grants current on 1st January 2003 or received after this date.

Please note that the assignment of a theme to a grant indicates that the theme 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 socio-economic theme.
