  Among the current sample of over 2000 radio pulsars known primarily in the
disk of our Galaxy, millisecond pulsars now number almost 200. Due to the
phenomenal success of blind surveys of the Galactic field, and targeted
searches of Fermi gamma-ray sources, for the first time in over a decade,
Galactic millisecond pulsars now outnumber their counterparts in globular
clusters! In this paper, I briefly review earlier results from studies of the
Galactic millisecond pulsar population and present new constraints based on a
sample of 60 millisecond pulsars discovered by 20 cm Parkes multibeam surveys.
I present a simple model of the population containing $\sim 30,000$ potentially
observable millisecond pulsars with a luminosity function, radial distribution
and scale height that matches the observed sample of objects. This study
represents only a first step towards a more complete understanding of the
parent population of millisecond pulsars in the Galaxy and I conclude with some
suggestions for further study in this area.
