We have performed Monte Carlo simulations of the Galactic supernova (SN), supernova remnant (SNR) and pulsar (PSR) populations, and find that even if every SN forms a fast-spinning pulsar, the number of shell type remnants which are expected to have an associated pulsar is even less than observed. We conclude that most shell SNRs will not have a detectable pulsar associated with them, and that many claimed associations are merely geometric projection.
