There appears to be continuing confusion as to whether or not counts of extragalactic radio sources are compatible with the steady state theory. Ryle and Clarke found considerable discrepancies between the observed counts and those predicted on the basis of steady state. Hoyle argues that the source counts are in agreement with the steady state theory except for a deficiency of only 5 sources per steradian at the bright end. I present here an explicit derivation of source counts expected in the steady state on the basis of identifications and redshifts of a complete sample of radio galaxies and quasi-stellar sources.
