### Description

The {\sc Majorana Demonstator} will field an array of approximately 60 kg. of high-purity germanium crystals. Some of the crystals will be enriched in the double-beta decaying $^{76}\mathbf{Ge}$ isotope. The {\sc Majorana Demonstrator} will search for the neutrinoless double-beta decay mode, as well as light WIMP dark matter. The primary experimental challenge is the reduction and estimation of residual radioactive backgrounds. This reduction is achieved by a combination of extremely pure and clean materials, an underground location, passive and active shielding, and data-analysis methods. This poster describes the quantitative background model of the {\sc Majorana Demonstrator} that takes into account all known sources of residual background radioactivity and the efficacy of the background mitigation schemes.
