  We make use of a previous well tested Galactic model, but describing the
observational behavior of the various stellar components in terms of suitable
assumptions on their evolutionary status. In this way we are able to predict
the expected distribution of Galactic White Dwarfs (WDs), with results which
appear in {\em rather good} agreement with recent estimates of the local WD
luminosity function. The predicted occurrence of WDs in deep observations of
selected galactic fields is presented, discussing the role played by WDs in
star counts. The effects on the theoretical predictions of different White
Dwarfs evolutionary models, ages, initial mass functions and relations between
progenitor mass and WD mass are also discussed.
