We find the corresponding regions of parameters in the minimal supergravity model for which the lightest neutralino is the cdm particle. We then compare with the muon anomalous magnetic moment ($a_μ$) measurement, the mass of the lighter CP-even Higgs boson ($h^0$), the trilepton search at the upgraded Fermilab Tevatron collider, and a direct search for relic neutralinos. The intersection of $Ω_{\rm cdm} h^2$ and $a_μ$ constraints selects $\tanβ\approx 40-45$.10 pages in REVTEX, 2 figuresHigh Energy Physics - PhenomenologyAstrophysicsImplications of New CMB Data for Neutralino Dark Mattertext
