The ubiquity of supermassive black holes in bulge-dominated galaxies, combined with the remarkably tight correlation between bulge properties and central black hole mass, strongly suggest that there is an evolutionary connection between supermassive black holes and their surrounding bulges. I use the demographics of local accreting black holes to investigate this picture in detail. I first discuss ongoing efforts to establish the occupation fraction of black holes in late-type galaxies. I show that galaxies without classical bulges may host black holes, but that the mode of black hole growth seems to be different in this regime. I then turn to luminous narrow-line quasars; in these systems, because the accretion luminosity is obscured, we have an unprecedented view of the host galaxy structure and stellar populations. With these systems, we may have the chance to witness the concurrent growth of black holes and bulges, and place limits on the importance of black hole feedback to the evolution of the host galaxy.
