Number distributions in period, period first time derivative, surface magnetic field strength, and distance obtained for the whole populations of radio or γ-ray visible pulsars in the simulations (light grey histogram) and in the LAT and radio survey data (thick line). The ATNF radio sample has been restricted to the objects that pass the same position and flux selection criteria as in the simulation. The slot-gap model has been used as an example for the γ-ray simulation. The dark shaded histograms show the distributions of the gamma active subsample of the whole simulated population. The abundances of simulated objects at low P, high Ṗ, and high B are dominated by γ-ray active pulsars. The excess of energetic and nearby simulated objects reflects the set of assumptions adopted for the birth distributions to provide a better match to the LAT data.
