It is shown that normal radio pulsars are not distributed symmetrically relative to the galactic plane. In directions toward the galactic center, the plane of symmetry of the pulsars lies an average of 50 pc above the galactic plane, and in directions toward the anticenter, an average of 100 pc below this plane. The distribution of all pulsars relative to the plane of the galaxy can be represented by an exponential function with a characteristic distance from the galactic plane of roughly 300 pc. The characteristic distance ranges from 130–420 pc depending on the age of the pulsars. The distribution of the surface density of pulsars is found to have a maximum at a distance of roughly 3–4 pc from the galactic center. The density of pulsars in the central region of the galaxy is roughly the same as that in the vicinity of the sun.
