Theoretical and analytical techniques which permit linking the properties of stars in the solar neighborhood to those in the rest of the Galaxy are explored. Consideration is given to the effects of assuming that the phase-space density of the local stellar population is accounted for by the energy exhibited by the objects, or by the energy and the angular momentum. The implications of both assumptions are discussed in terms of the effects observed when the calculations are performed with a flattened, instead of spherical Galaxy. Solar neighborhood probability densities are examined for their suitability as a guide to estimating the total galactic population of stars as a function of the population within the action space of the solar neighborhood.
