The effect of galaxy interactions and other gravitational perturbations on nuclear activity has been investigated using data release five of the Sloan Digital Sky Survey (SDSS). Both the imaging and spectroscopy data products were used to construct a volume-limited sample of relatively nearby galaxies that also produce an AGN spectrum. The sample has been analyzed using the subjective morphological analysis pioneered by Dahari (1984, 1985) and MacKenty (1990). The high-resolution sky coverage of the SDSS allows for definition of a complete and unbiased sample and provides superior multicolor optical imaging of the AGN environments. The results of this student-led project modify the conclusions of previous investigations and indicate that for all AGN gravitational perturbations are always present in the host galaxies.
