A self-gravitating, elastic, spherical thick shell model is used to derive the present state of the lateral variations of density and stress within the lunar interior. Density perturbations are generally +/-200 kg/m 3 within the crustal layers, with peaks of up to +/-400 kg/m 3. These perturbations diminish quickly with depth, becoming less than +/-80 kg/m3 by 150 km depth, and generally less than +/-5 kg/m3 by 300 km depth. The major stress differences associated with the mascon basins are found in the upper mantle reaching maximums of 6--8 MPa at about 150 km depth. The introduction of a partially molten layer in the upper mantle increases the stresses in the overlying strata significantly. The stresses for this type of model reach values above 10 MPa beneath the major mascon basins, between the base of the crust to the top of the partially molten layer, at 180 km depth.
