In this paper we review our results on the properties and evolution of isolated neutron stars. We calculate space distributions of these objects for different assumptions about the kick velocity and show, that the distribution has a torus-like structure. We calculate the evolution of isolated neutron stars with and without magnetic field decay and give characteristic parameters for these cases with applications to ROSAT X-ray sources. And finaly, our most recent results are connected with the type distribution of isolated neutron stars in the Galaxy. We show, that for kick velocities about several hundred km/s (as it is proposed by radiopulsars observations) most neutron stars are not at the Accretor stage but at the Ejector stage and can not be observed as X-ray sources.
