Abstract. We consider the Anderson model on the lattice $\mathbb{Z}^{d}$ and prove a positive lower bound on the density of states under certain conditions. For example, if the random variables are independently and identically distributed and the probability measure has a bounded density with compact support, and if the Lebesgue density is essentially bounded away from zero on its support, then we prove that the density of states is strictly positive Lebesgue almost every energy in the deterministic spectrum.
