Using a likelihood analysis and EGRET detections , upper limits and diffuse background measurements , we find a best-fit luminosity law L \propto P ^ { -1.7 } B ^ { 1.2 } for the gamma-ray pulsar population . We find that roughly 30 of the 170 unidentified EGRET sources are likely to be pulsars . This is roughly twice the number of known radio pulsars which are plausibly associated with unidentified EGRET sources . We predict that AGILE will detect roughly 70 pulsars as point sources , including 12 which will be able to be detected in blind periodicity searches . GLAST should detect roughly 1200 pulsars ( including only 200 currently known radio pulsars ) , 210 of which will be able to be detected in blind searches . We discuss methods of searching for pulsars in gamma-ray data and present results from our searches for gamma-ray periodicities from new radio pulsars associated with unidentified EGRET sources .
