| Abstract: | Based on a large volume of statistical data it is shown that the spatial distributions of radio pulsars in the galaxy with
characteristic ages T ≤ 10
6
years and T > 106 years differ significantly. The overwhelming majority of the pulsars with T ≤ 10
6
years lie within a narrow band of width 400 pc around the galactic plane. A large portion of the pulsars with T > 106 years is concentrated outside this zone. In the case of younger pulsars, a larger fraction of them lies within the confines
of the above mentioned zone. It is also shown that pulsars with T ≤ 10
6
years and the remnants of supernova explosions have essentially the same spatial distribution. These facts support the existence
of a relationship between pulsars and supernova remnants, as well as the acquisition of high spatial velocities by pulsars
during their birth.
