  We analyze the counts of low-redshift quasar candidates selected using
nine-epoch SDSS imaging data. The co-added catalogs are more than 1 mag deeper
than single-epoch SDSS data, and allow the selection of low-redshift quasar
candidates using UV-excess and also variability techniques. The counts of
selected candidates are robustly determined down to g=21.5. This is about 2
magnitudes deeper than the position of a change in the slope of the counts
reported by Boyle et al. (1990, 2000) for a sample selected by UV-excess, and
questioned by Hawkins & Veron (1995), who utilized a variability-selected
sample. Using SDSS data, we confirm a change in the slope of the counts for
both UV-excess and variability selected samples, providing strong support for
the Boyle et al. results.
