Scientific paper

A simple, though not necessarily unique, model for the cosmic population dynamics of quasars is presented. This model incorporates a double evolutionary trend: a strong luminosity evolution and an evolution of total coordinate density. This double trend is the same as that already found to be applicable to the total radio-source population, if account is taken only of radio characteristics. The predictions of the scheme are compared with five sets of data, covering a wide range of frequencies and flux-density limits, and they are found to give good agreement in all cases.
