Using over 10000 galaxies between 0.05 < z < 0.095 and brighter than Mr = -20.0, we find at least ~20% of these galaxies possess an unambiguous detection of an AGN. This fraction could be as high as ~40% after we model the ambiguous emission line galaxies in our sample. We have studied the spatial distribution of these AGN and show that they exist in all environments (from dense to sparse) and that their two-point spatial correlation function is identical to the general galaxy population. We compare this correlation function to recently developed models. We conclude that the presence of an AGN is independent of the disk component of a galaxy. Our observations are consistent with the hypothesis that a supermassive black hole resides in the bulge of all massive galaxies and ~40 holes are seen as AGNs in our sample.
