We highlight the correlation between a galaxy’s supermassive black hole mass and theS´ersic-index of the host spheroid or bulge component. From our bulge-disk decompositions of 10 095galaxies, drawn from the Millennium Galaxy Catalogue, we construct the local (z < 0.18) mass functionof supermassive black holes. We compare our results to those of McLure & Dunlop (2004) and concludethat the mass density of supermassive black holes may be marginally higher than previously supposed.This increase is predominantly due to the inclusion of low mass and later-type bulges. More details willbe presented in a forthcoming paper.
