Recent Sloan Digital Sky Survey data from observations of over 590 spectroscopic plates yield more than 20,000 spectroscopically confirmed QSOs with at least one emission line having FWHM > 1000 km/sec. The quasar target selection algorithm (Richards et al., 2002) selects low-redshift quasars (z<3) and FIRST sources to i=19.1, as well as high-redshift quasars (z>3) to i=20.2. We apply the selection function in (redshift, magnitude) space to the QSO sample to determine the density and luminosity evolution of quasars. We present the comoving space density, as a function of absolute magnitude and redshift. Funding for the SDSS is provided by the Alfred P. Sloan Foundation, NASA, NSF, DOE, Monbukagakusho, the Max Planck Society and the member institutions. The SDSS web site is http://www.sdss.org/.
