Co-moving number density of the jetted population associated with SDSS J0100+2802 and SDSS J0306+1853 (orange and red squares, respectively), compared to the space density of quasars with L_bol > 10⁴⁷ erg s⁻¹, 2 × 10⁴⁷ erg s⁻¹, and 8 × 10⁴⁷ erg s⁻¹ from Shen et al. (2020, dashed light blue, solid blue, and solid green lines). The densities extracted from the two sources are calculated for viewing angles of 40° and 30°, and the smallest angles, i.e. 13° for SDSS J0306+1853 and 16° for SDSS J0100+2802, are derived from SED fitting. According to these estimates, the whole quasar population is hosted in jetted AGNs at z > 5.
