  Recent results from the WMAP measurements of the cosmic background radiation
yield very tight constraints on the relic density of supersymmetric cold dark
matter. We combine the WMAP constraint with those from the anomalous magnetic
moment of the muon and the b -> s gamma branching fraction in a chi^2
determination over the minimal supergravity model (mSUGRA) parameter space. The
most favored region of mSUGRA parameter space for almost all tan(beta) values
is the hyperbolic branch/focus point (HB/FP) region, with moderate to small
values of superpotential Higgs mass |mu| and large GUT scale scalar mass m_0.
These favored regions of mSUGRA parameter space can be probed by direct search
experiments for supersymmetric dark matter. An exception to the HB/FP region
can occur at very large tan(beta) with positive mu values, where wide regions
allow resonance annihilation of neutralinos in the early universe.
