Simulations are conducted of the evolution pulsars on the assumption that they evolve by emitting magnetic dipole radiation and have magnetic fields decaying according to the power law with index of -1/4. Simulations are also conducted on the assumption that the pulsars retain constant magnetic fields. Monte Carlo techniques are used to generate sample pulsars of particular distributions of initial periods, period derivatives, magnetic dipole moments, luminosities, and Galactic positions. The period-dependent beaming fraction of pulsars is considered in the simulation. Known selection effects which affect the actual observation are taken into account as accurately as possible. Then best fits are found by comparing the result of the simulation with the observed data of the pulsars. The constant magnetic field model can account for the observed data comparatively well, and the power-law decay model with index of -1/4 does considerably less satisfactorily.
