We present the Bright Quasar Survey (BQS) consisting of 114 objects to an average limiting magnitude B = 16.16 over an area of 10,714 deg/sup 2/. There are 92 quasars with M/sub B/<-23 in the sample. We use the BQS and complete samples from published surveys to derive models of the statistical evolution of quasars. The increase of space density with redshift depends strongly on absolute luminosity, being close to zero for low-luminosity quasars. Detailed predictions are given for the distribution of redshifts and magnitudes and for the total counts based on the evolution models.
