  On the basis of theoretical evolutionary expectations, we develop a Galactic
model reproducing star counts and synthetic color-magnitude diagrams of field
stars, which include the white dwarf (WD) population. In this way we are able
to evaluate the expected occurrence of WDs in deep observations at the various
photometric bands and Galactic coordinates, discussing the contribution of the
WDs of the various Galactic components. The effects on the theoretical
predictions of different WD evolutionary models, ages, initial mass functions
and relations between progenitor mass and WD mass are discussed.
