A hypothesis involving spindown due to radiation and spinup due to accretion is proposed to explain why some pulsars have very small period derivatives. It is argued that the assumption that all pulsars are produced close to the galactic plane and are moving away from it is valid only for a subset of pulsars. A classification scheme is outlined, according to which three types of pulsar are distinguished on the basis of mode of formation. Pulsars produced by supernova explosions of single stars are designated type S; these are formed close to the galactic plane and acquire large velocities due to asymmetries in the explosion. Pulsars produced by supernova explosions in close binaries are designated type L if the binary is not disrupted or type D if disruption ensues. It is suggested that type L and type D pulsars are produced at large vertical distances from the galactic plane, that type L pulsars are neutron stars 5 to 7 million years old, and that the Crab pulsar is type D.
