  The EGRET telescope on the Compton Gamma-Ray Observatory detected over 200
sources and the majority of these are still unidentified. At least three
subpopulations of EGRET sources have been associated with the Galaxy: bright
sources lying along the Galactic plane, weaker sources spatially correlated
with the Gould Belt and a high-latitude, halo population. Many of these sources
may be pulsars and there are more than two-dozen radio pulsars in or near EGRET
source error boxes, most of them recently discovered in the Parkes Multibeam
Survey. We present results from several population synthesis studies of pulsars
in the Galaxy, which predict the number of pulsars detected by gamma-ray and
radio surveys assuming models for the high-energy emission beam and its
relation to the radio beam. Future gamma-ray pulsar detections by AGILE and
GLAST together with the recent large rise in the radio pulsar population will
give greatly improved statistics. The relative numbers of radio and gamma-ray
pulsars detected in the plane and in the Gould Belt populations will provide an
important discriminator between models of high-energy emission and will
profoundly affect the numbers and birth rate of pulsars in the Galaxy.
