Top: average environmental densities of radio-quiet quasars, Seyfert galaxies, FR I radio galaxies, and flat-spectrum radio galaxies as a function of redshift. Bottom: average environmental densities of radio galaxies in three luminosity bins as a function of redshift. Densities are in units of mean densities and the errorbars show the standard errors of the average.
